#snsinstitution #snsdesignthinkers #designthinking Hey Connection, I had glad to say about the semiconductor Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium, or compounds such as gallium arsenide or cadmium selenide. Semiconductors are an essential component of electronic devices, enabling advances in communications, computing, healthcare, military systems, transportation, clean energy, and countless other applications. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called "metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common semiconductor and is used in laser diodes, solar cells, microwave-frequency integrated circuits, and others. semiconductor is a material that has electrical resistance more than conductors and less than insulators so that it can conduct current not as fast as conductors but does not restrict the flow of current as insulators. So it kind of “semi” conducts the current P-type semiconductors are doped with acceptors since they can accept electrons while n-type semiconductors are doped with donors since they 'donate' the free … N-type semiconductors have an excess of electrons, while p-type semiconductors have an excess of "holes" where an electron could exist. Semiconductors are devices that have conduction between a conductor and insulators and are used in everyday life in many devices like transistors, zener diodes, solar panels, switches, electric circuits, etc. Semiconductors are divided into two types, intrinsic semiconductors, and extrinsic semiconductors semiconductor substance lies between the conductor and insulator. It controls and manages the flow of electric current in electronic equipment and devices. As a result, it is a popular component of electronic chips made for computing components and a variety of electronic devices, including solid-state storage.

**50 DAYS 9F MICROELECTRONICS AND SEMICONDUCTORS** Hey there.. It's me again. Abdullah Tiamiyu is my name. I'm keeping my promise, and this is my new release. Do stay with me. *WHY DO WE NEED EXTRINSIC SEMICONDUCTORS IN THE INDUSTRY?* Extrinsic semiconductors play a vital role in modern electronics because they give us the ability to control a material's conductivity with incredible precision—something intrinsic semiconductors alone can't achieve. Intrinsic semiconductors rely solely on naturally occurring electron-hole pairs, which limits their conductivity and current-carrying capacity. By introducing specific impurities into these materials—a process known as doping—we can create extrinsic semiconductors with significantly enhanced conductivity. Depending on the impurity used, we can add extra electrons (n-type) or create additional holes (p-type), allowing us to fine-tune their properties. This level of control is the backbone of modern technology, enabling the creation of diodes, transistors, and integrated circuits—the core components of virtually every electronic device we use today. Without extrinsic doping, the advanced electronics that define our world would simply not exist. How about a bonus? Here you have it.. Semiconductor compounds are the backbone of modern technology, each with its own strengths tailored to specific applications. 1. Silicon (Si) is everywhere in electronics, powering transistors, integrated circuits, and solar panels. It’s the go-to material for microelectronics. 2. Gallium Arsenide (GaAs) shines in high-frequency devices like microwave circuits and laser diodes, making it essential for communication systems. 3. Silicon Carbide (SiC) is perfect for high-power needs, especially in electric vehicles and energy-efficient converters. 4. Indium Phosphide (InP) is the hero of fiber optics, enabling fast data transfer and precise imaging. Together, these materials drive innovation across countless industries. @Nivas Ravichandran @Kayne McGladrey @Gloria W.

Day 5 of 50: Exploring Compound Semiconductors in Microelectronics Today, let’s dive into the world of compound semiconductors, a fascinating class of materials that have significantly advanced modern electronics and optoelectronics. Unlike silicon, which is an elemental semiconductor, compound semiconductors are made from two or more elements, often from groups III-V or II-VI of the periodic table. Their unique properties, such as tailored bandgaps and high electron mobility, make them indispensable in cutting-edge applications. Let’s take a closer look at six prominent compound semiconductors: GaAs, GaN, SiC, InP, ZnSe, and IGZO. Gallium Arsenide (GaAs) features a direct bandgap of 1.43 eV, making it highly efficient for light emission and absorption. It’s widely used in high-speed electronics, solar cells, LEDs, and laser diodes. Gallium Nitride (GaN), with a direct bandgap of 3.4 eV, is known for its excellent thermal stability and high electron mobility. GaN is a key material for blue and white LEDs, power devices, and RF amplifiers, particularly in 5G communication systems. Silicon Carbide (SiC), on the other hand, has an indirect bandgap ranging from 2.3 to 3.3 eV depending on its polytype. Its ability to handle high temperatures and voltages makes it ideal for power electronics, EV inverters, and industrial motor drives. Indium Phosphide (InP), with a direct bandgap of 1.34 eV, is the cornerstone of high-speed communication systems, especially in fiber optics and satellite technologies. Zinc Selenide (ZnSe) is a direct bandgap material (2.7 eV) widely used in green and blue laser diodes, medical imaging, and infrared optics. Finally, IGZO (Indium Gallium Zinc Oxide) stands out for its transparency and low power consumption. It’s a game-changer for TFTs in modern displays and flexible electronics. These materials form the backbone of everything from power devices to cutting-edge displays, demonstrating the versatility and importance of compound semiconductors in today’s world. #ieee #semiconductors #microprocessors #microelectronics

DAY 2 : 50 DAYS DISCUSSION ON MICROELECTRONICS DEVICES AND CURCUITS Extrinsic semiconductors are essential in microelectronics because they enhance the electrical properties of intrinsic semiconductors, making them more suitable for various applications. By adding impurities, or dopants, to the semiconductor material, we can create either n-type or p-type semiconductors. This process allows for better control over the conductivity and enables the formation of p-n junctions, which are critical for diodes, transistors, and other electronic components. The ability to tailor the electrical characteristics of semiconductors is fundamental to the performance of microelectronic devices. In terms of compound semiconductors, three notable examples include gallium arsenide (GaAs), indium phosphide (InP), and silicon carbide (SiC). GaAs is widely used in high-frequency applications and optoelectronics, such as LEDs and solar cells, due to its direct bandgap and high electron mobility. InP is known for its application in high-speed and high-frequency devices, particularly in telecommunications, as it offers excellent performance in the infrared range. SiC, on the other hand, is valued for its high thermal conductivity and electric field breakdown strength, making it ideal for power electronics and high-temperature applications. These compound semiconductors play a crucial role in advancing microelectronics, enabling the development of faster, more efficient, and more reliable devices. As we continue our 50-day discussion on microelectronics devices and circuits, it's fascinating to explore how these materials contribute to the innovation and performance of modern technology.

"Two-dimensional (2D) semiconducting materials have distinct optoelectronic properties that could be advantageous for the development of ultra-thin and tunable electronic components. Despite their potential advantages over bulk semiconductors, optimally interfacing these materials with gate dielectrics has so far proved challenging, often resulting in interfacial traps that rapidly degrade the performance of transistors. Researchers at King Abdullah University of Science and Technology (KAUST), Soochow University and other institutes worldwide recently introduced an approach that could enable the fabrication of better performing transistors based on 2D semiconductors. Their proposed design, outlined in a paper in Nature Electronics, entails the use of hexagonal boron nitride (h-BN) dielectrics and metal gate electrodes with a high cohesive energy." #2Dsemiconductor #optoelectronic
