Chemical Vapor Deposition of ?-Boron Layers on Silicon for Controlled Nanometer-Deep p+n Junction Formation

Nanometer-thick amorphous boron (?-B) layers were formed on (100) Si during exposure to diborane (B2H6) in a chemical vapor deposition (CVD) system, either at atmospheric or reduced pressures, at temperatures down to 500°C. The dependence of the growth mechanism on processing parameters was investigated by analytical techniques, such as...
