MEMS Gyroscope: Sensitive Structure | Detection Circuit | Integrated Package MEMS gyroscope is a kind of MEMS inertial sensor which uses Coriolis effect to detect the rotational angular rate of objects. It can integrate the sensitive structure and peripheral measurement and control circuit on the same silicon chip, and has the advantages of low cost, small size, light weight and low power consumption. The sensitive structure is the core component of MEMS gyro sensor, which is directly related to the performance of the gyroscope such as scale factor, zero bias and anti-vibration. This paper will introduce the basic knowledge of MEMS gyros in detail from the sensitive structure, detection circuit and integrated package of MEMS gyroscope.

🧮 Accurate and predictive first-principles calculations of spectral properties of materials, such as the band gap of semiconductors, are key to understanding, discovering and designing materials for countless applications including electronics, energy harvesting, and photonics. ✍️ In a new article published in the journal Physical Review Research, Antimo Marrazzo from SISSA, and Nicola Colonna, from the Paul Scherrer Institute in Villigen, Switzerland, advocate for a paradigm shift by introducing a new functional approach that allows calculating band structures of semiconductors in a simple way and at low computational cost, even in presence of spin-orbit coupling or complex magnetic configurations. 🔎 This development will make computational screenings of materials databases much more efficient and accurate, and enable simulating complex materials under more realistic conditions, such as in presence of defects or at finite temperature. 📑 Read more about this research in our latest press release: https://lnkd.in/epup2d9Z

Vintage collection! You recognize this instrument? Around 1993 Raith and Orsay Physics built a very early and special FIB-SEM system for the Paul Scherrer Institute, Zurich, Switzerland. In this case, the FIB with ExB filter was top mounted and the SEM came from the back under an angle. One requirement was, that the chamber vacuum should reach „nearly“ ultra high vacuum. As a „one off“, I would not say that it was a very mature solution, but already an impressive piece of engineering at that time. Products may not be successful because they were ahead of their time, or too special, or not mature enough, or – even worse – killer applications weren´t well understood, like those in semiconductor failure analysis. But some „seeds“ were laid down for the companies success in FIB later.

New Publication This study explores advanced photoactive CO-releasing materials using heterocyclic structures. It reveals strong Mn(CO)₃-heterocycle interactions in ground states and weakened CO binding in excited states, facilitating CO release. Quantum chemical and AIM analyses confirm changes in electron density and bond elongation, highlighting the potential of these molecules for efficient CO delivery. The work was in collaboration with Anik Sen GITAM Deemed University #researchinGITAM #GITAM #CTC #ComputationlChemistry

I am pleased to share our most recently published paper on the optoelectronic properties of penta-NiN2. We investigate them including quasiparticle effects within many-body perturbation theory, employing the #YAMBO code. Check this out! https://lnkd.in/dcsNJcnS

Our latest article on SiC. If you are working on WBG semiconductor based electronics then this article may be helpful to you. This paper studies the temperature-dependent electrical transport properties of nickel (Ni) and nickel–chromium (Ni–Cr) sputtered on n-type 4 H-SiC substrate. Barrier inhomogeneities have been found to affect the electrical parameter of the Schottky barrier diode (SBD) from 323 to 423 K temperature range, We have done current–voltage characterization of Ni and Ni–Cr Schottky junctions. The barrier height , reverse saturation current , ideality factor and series resistance were obtained from I–V characteristics of Ni and Ni–Cr and these parameters are observed to be highly dependent on temperature. It has been observed that Ni–Cr contact has exhibited better electrical characteristics as well as thermal sensitivity as compared to Ni. Detailed discussion is available in the article.

Dear Colleagues, We are delighted to invite you to contribute to the Special Issue “Metal Oxide Semiconductors: Synthesis, Structure, and Applications”. Oxides find applications in many areas of technological relevance. This stems from their abundance and their many beneficial properties (structural, electronic, magnetic, etc.) which make them potential candidates for many applications. This Special Issue is dedicated to recent developments in the synthesis of oxidic materials, their relationship with synthesis routes, their structure (e.g., at the electronic level), and their performance in operando. This Special issue aims to report on efficient characterization techniques, both at theoretical and experimental levels, of different class of oxides, including bulk and material systems with low dimensions (2D, 1D, and 0D), that allow a rational design of, and provide fundamental insights into, key properties governing their performance in operando. In this Special Issue, original research articles, communications, and reviews are welcome. Research areas may include (but are not limited to) the following: surface science, heterogeneous catalysis, energy conversion, electronics, optoelectronics, spintronics, corrosion, environmental science, and tribology. I look forward to receiving your contributions. Dr. Stephane Kenmoe Guest Editor To contribute to the special issue : https://lnkd.in/ecZ2xdiR
