Ion drift in the electric field of a depleted region has been studied
at about room temperature in intentionally Cu-doped p-type Hg0.3Cd0.7T
e bulk materials. Capacitance-voltage measurements have mainly been us
ed to investigate the drift of interstitial copper. Diffusion data of
copper has been obtained using classical theoretical models based on t
he dissociation-formation of acceptor-donor complexes (A(s)D(i)). The
possibility of junction creation by this ion manipulation under a stro
ng electric field is discussed.
