In order to understand dislocations in GaN grown on silicon using metal organic chemical vapor deposition (MOCVD), two samples with different film thickness were grown. The distribution of dislocations and its influence on epitaxial layer were studied. Wet etching can effectively reveal the dislocations in GaN, [...]

Silicon carbide has very stable characteristics, so that it can work stably in some harsh environments. Because of the stable chemical bonds, the technical threshold for silicon carbide production is very high. The growth conditions of silicon carbide crystal ingots are harsh, requiring high temperature (~2600℃) and high [...]

Germanium was an early transistor material. Now its charge-carrying abilities and advanced fabrication technology make it an attractive material for future chips. As a proof of concept, our team used germanium-on-insulator wafers to construct inverters containing first planar transistors and then FinFETs
Germanium was first [...]
