SiC wafer can be used to manufacture BJT (bipolar junction transistor) devices with low conduction resistance and high blocking voltage up to tens of kilovolts. For applications with a blocking voltage of 4.5kV and higher, bipolar SiC power devices will have more practical application value than unipolar SiC power [...]

This letter describes the heteroepitaxy of InP on Si by MOCVD. A new epitaxial structure with a thin GaAs intermediate layer (InP/GaAs/Si) is proposed to alleviate the large lattice mismatch (8.4%) between InP and Si. Using this structure, a 4-inch InP single crystal with [...]

Near-band-edge luminescence in heavily doped gallium arsenide
The near-band-edge photoluminescence at 80K of heavily tellurium-doped degenerate liquid-phase-epitaxial gallium arsenide layers (n=2*1018 cm-3) is investigated. The layers are compensated with shallow germanium acceptors (the values of the degree of compensation are K=0.05-0.7) during the epitaxial growth process. [...]
