Abstract

P doping of Si during growth by molecular beam epitaxy (MBE) has been investigated in the temperature regime 700 oC to 870 oC. By designing a growth sequence that fully accounts for the P deposited in a delta-doped layer, and then tracks the P as it segregates into the undoped Si and traps the surface P in a low temperature Si cap, it was determined that the onset of significant P evaporation during growth occurred at a substrate temperature of 663  10 oC. The P sublimation process had an activation energy of 199  22 kJ/mole.
