Funneling-current transients produced in semiconductor devices are predicted to occur on a picosecond time scale. The authors measured these transients using a high bandwidth sampling system. Measurements were made on 1, 3, and 10 ..cap omega..-cm silicon low capacitance diode and 10/sup 16/ cm/sup -3/ Te-doped GaAs diodes. The data is compared to the Hsieh, Murley and O'Brien, the McLean and Oldham, and the Messenger models. Risetime versus doping density, peak current, total charge, and amplitude versus bias were measured. Also, current transients and prompt charge versus energy are presented.
