Interface reaction and formation of La- silie gate

Silicon Carbide (SiC) is one of the IV-IV group element semiconductor, which was first artificially synthesized by Acheson in 1882. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Electronic appliions of SiC as light-emitting diodes (LEDs) and detectors in early radios were first demonstrated around 1907.
