文摘

C and Si delta doping in Ge is investigated using RPCVD system by CH3SiH3 exposure.

Atomically flat C and Si delta layers are fabricated at 350 °C.

Incorporated C and Si doses are saturated at one mono-layer below 350 °C.

CH3SiH3 adsorption occurred without decomposing Csingle bondSi bond.

Adsorbed C is desorbed due to dissociation by hydrogen during postannealing at 550 °C.
