Hi there, today is day 2/50 of me making a post talking about semiconductor electrophysics and integrated circuits. The Importance of Extrinsic Semiconductors There are Intrinsic and extrinsic types of semiconductors. The major reason why the switch from Intrinsic to Extrinsic is important is that the intrinsic limitation is limited electrical conductivity, which makes it unsuitable for electronic devices. This switch actually happens by doping, which means adding impurities to Intrinsic materials, thereby making them Extrinsic materials, which in turn have enhanced electrical properties. The Advantages : ·      Improved Conductivity: By doping a semiconductor with specific elements, the charge carrier concentration can be improved. Good examples include doping Silicon with Phosphorus which results in an n-type semiconductor, while dopin that same silicon with boron will result in a p-type semiconductor. ·      Versatility: Extrinsic semiconductors can be used for various range of applications, from low-power devices to high-frequency communication systems and this is due to their high adaptability. Compound Semiconductors and their uses 1.      Gallium Arsenide (GaAs): · High-frequency devices such as microwaves, switches, and detectors. ·      Optoelectronic devices such as photodetectors, and laser diodes amongst others. 2.      Indium Phosphide (Inp): ·      High-speed electronics such as transistors, amplifiers, and switches. ·      Optical communication systems like optical amplifiers. 3.      Gallium Nitride (GaN): ·      Power electronics like transistors, amplifiers, and switches. ·      RF and microwave applications like detectors, amplifiers, and switches.

⚡️THE MICROELECTRONICS DIARIES : 50 DAYS OF DEVICES , CIRCUITS AND INNOVATIONS!⚡️ Day 2/50 NEED FOR EXTRINSIC SEMICONDUCTORS Intrinsic semiconductors, like pure silicon or germanium, have limited conductivity and are not suitable for most electronic applications.

🔧 Resistivity vs. Doping Concentration: Insights into Semiconductor Behavior In semiconductors, resistivity (p) is a key parameter that determines how easily current flows. This graph showcases how (p) changes with doping concentration (Na) for silicon (Si), germanium (Ge), and gallium arsenide (GaAs). 📊 Key Observations: 1️⃣ Inverse Relationship: As doping increases, resistivity decreases. This is because adding dopants increases free carrier concentration, improving conductivity. 2️⃣ Material Comparison: - GaAs has the lowest resistivity for a given doping level, thanks to its high electron mobility. - Ge follows closely due to its superior mobility compared to Si. - Si, while widely used, shows higher resistivity due to relatively lower mobility. 3️⃣ Why It Matters: - Understanding resistivity helps engineers design devices like transistors, diodes, and solar cells with precise electrical properties. This simple yet powerful relationship drives the innovation in semiconductor technology powering modern electronics! 🌟 What do you think of these trends? #Semiconductors #ElectronicsEngineering #MaterialsScience #Innovation IEEE IEEE Circuits and Systems Society (CASS) IEEE Education Society (EdSoc)

SiC chips & HF Litz Wire: Perfect symbiosis for more efficiency Silicon carbide, or SiC for short, is becoming increasingly important. In the electronics industry there is even talk of the “SiC revolution” and chip manufacturers worldwide are increasing their production capacities for semiconductors made from the diamond-like material. Handelsblatt calls silicon carbide “the material of the future” and the semiconductors made from it “energy-saving chips”. Not only the automotive and energy industries now rely on SiC semiconductors, but also all industries in which modern power electronics are required. This is because SiC semiconductors have a significantly higher energy density, better thermal conductivity, higher switching power and lower switching losses than conventional silicon semiconductors. They not only set new standards in switching voltage, switching speed and switching losses, but also make power electronics components significantly smaller and lighter. With our high-frequency Litz Wire made of enamelled copper wire, we have another booster for power electronics up our sleeves: The combination of SiC semiconductors with HF Litz Wire plays the following trump cards: - Further reduction of power losses thanks to lower resistance and loss values of copper - Further improved heat dissipation thanks to the excellent thermal conductivity of copper - Minimization of parasitic effects such as oscillations and resonances thanks to the low inductance of HF Litz Wire Are you looking for ways to make your power electronics components even more efficient with SiC semiconductors?

Sometimes I think I need to stop and reflect on the amazing progress which has been made in power semiconductors over the last two decades. When I first starting working in power electronics (ok, a long time ago!) Silicon Carbide (SiC) and Gallium Nitride (GaN) power devices were not available. We had MOSFETs which seemed great at the time but SiC and GaN offer performance levels a world apart now. The plot below is captured from a hard-switched, GaN based power stage running at 500kHz, with switch voltage of 48V and switch current of ~50A. The PCB layout is very tight and we didn't use any snubbers. OK, we may need to add some to meet EMC but the point is this switching waveform is so natively clean, especially considering the timebase here is just 500ns/div. So, why is this good? Well, switching behaviour this clean is indicative of power devices which are moving closer to the perfect switch. This allows us to push to higher switching frequencies which can allow us to shrink the power converter size. Efficiency levels are well above 95% and, guess what, the vast majority of the total converter loss is in the magnetics now, not the semiconductors. My younger self would have been amazed to see this level of progress in semiconductor technology. This sort of technology coupled with real-time digital control is what underpins the electrification of many aspects of our lives. #emobility #stem #digitalcontrol #GaN #SiC
