Abstract
Oscillations of space charge limited currents in short doped p-quantum well bases of ballistic diodes as a result of a negative effective ma ss region in the quantized hole dispersion relation are considered. De tails of contact design (contact shape and Fermi-energy of injected ba llistic holes) strongly affect the generation regime. This regime has a maximum voltage range for flat contacts and for an optimal Fermi-ene rgy that would provide a quasineutral region in the diode base.
