摘要
Micro-Raman spectroscopy was used to characterize beveled Zn delta (delta)-doped GaAs structures. By adapting procedures previously developed for the study of Si delta-doped GaAs structures, Zn-doping profiles were obtained for a set of structures prepared with different doping levels. Values of the doping spike concentration and the full-width at half-maximum of the doping profile were compared with the values obtained by the electrochemical capacitance-voltage (EC-V) and secondary ion mass spectroscopy (SIMS) methods. The good correspondence between this Raman procedure and other well-known methods proves the validity of the technique for determining doping profiles in Zn delta-doped GaAs structures.
