摘要
We have experimentally studied the dynamics of impact-ionization switching in semiconductor structures without p-n junctions when subnanosecond high-voltage pulses are applied. Silicon n (+)-n-n (+) type structures and volume ZnSe samples with planar ohmic contacts exhibit reversible avalanche switching to the conducting state within about 200 ps, which resembles the well-known phenomenon of delayed avalanche breakdown in reverse-biased p (+)-n-n (+) diode structures. Experimental data are compared to the results of numerical simulations.
