The influence of the ‘hi’ doping level on the performance of hi-lo high-efficiency structures is considered. Computed results show the variations of various quantities as functions of ‘hi’-region doping density. These results enable estimates to be made of the maximum permissible ‘hi’ doping level for a range of frequencies, current densities and applications.
