Abstract: The reverse current-voltage characteristics of surface-barrier diodes based on $n$-CdTe with a surface modified by treating in an aqueous solution of alkali metal salts have been investigated. The reverse current is found to have a tunneling nature at low biases and be caused by avalanche multiplication of carriers as a result of impact ionization at high biases.
