Structure of a possible silicon-based MOSFET. The n--region is the voltage-sustaining part of the device and has most influence on its conduction properties. 2 1) For the sake of simplicity, E max is treated here as a constant, although it depends on factors such
Energy bands - University of Colorado Boulder
Band structure of silicon As an example we consider the band structure of silicon as shown in the figure below: Figure 2.3.12.: Simplified E-k diagram of silicon. Shown is the E-k diagram within the first brillouin zone and along the (100) direction. The energy is
The Quartz Page: Quartz Structure
To get an idea of quartz crystal structure and its symmetry properties, most figures show the crystal when viewed in the direction of either the a-axis or the c-axis (a and c in Fig.1.01). This corresponds to a projection of the atoms onto the a-plane and the c-plane, and not to a slice of the crystal: the atoms one sees actually lie in different planes along the a- and the c-axis.

Calcium carbide - Wikipedia
Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of Ca C 2.Its main use industrially is in the production of acetylene and calcium cyanamide. CaC 2 Molar mass 64.099 g/mol Appearance White powder to grey
The thyristor or silicon controlled rectifier, SCR has a structure that consists of four layers: it contains a PNPN sandwich. The thyristor structure is relatively straightforward and normally relies on processes that are well established. As a result thyristors are plentiful
CeramCool® Sandwich Heat Sink
Schematic diagram of the double-sided structure: in this system, the upper heat sink is soldered to the upper side of the chip so that the chip is cooled from both sides. To meet the growing demands in the power electronics field, it is necessary to reduce the thermal resistance between chip and heat sink, which is made possible by the “Chip-on-Heat sink” technology .
Phase Diagram - Industrial Metallurgists
Under these conditions it is possible to have phases missing or present compared to what is indied by the phase diagram. Therefore, it is also important to understand the kinetics of phase transformations, i.e. the effects of temperature, time, cooling rate, and heating rate on phase changes within an alloy.

This has been fueled by an increased focus on saving energy, reducing the size of devices, and improving the long term reliability of …
PCIM: First trench SiC mosfet is 2x better
Trench structures will halve the on-resistance of silicon carbide power mosfets, claimed Rohm. “Compared to existing planar-type SiC mosfets, on-resistance is reduced by 50% in the same chip size, making it possible to significantly decrease power loss,” said the firm.

Growth Mechanism of Cubic-Silicon Carbide Nanowires
Cubic-SiC nanowires were synthesized using activated carbon powder and Si substrate in vacuum at 1200–1350°C for 1–4 hours. The nanowires were grown according to the following proposed mechanisms: (1) diffusion of C/CO into Si substrate, (2) weakening of Si bond and atomic kick-out, (3) formation of Si-C in vapor phase, (4) formation of saturated SiC layer, (5) formation of pyramid-like
