2-20.Linear Crystallographic Defects
2-20.Linear Crystallographic Defects Crystalline solids exhibit a periodic crystal structure. The positions of atoms or molecules occur on repeating fixed distances, determined by the unit cell parameters. However, the arrangement of atom or molecules in most crystalline materials is not perfect. The regular patterns are [...]

5-6-4-2 SiC High-Power Switching Transistors
5-6-4-2 SiC High-Power Switching Transistors Three terminal power switches that use small drive signals to control large voltages and currents (i.e., power transistors) are also critical building blocks of high-power conversion circuits. However, as of this writing, SiC high-power switching transistors are not yet commercially [...]
