TRANSIENT DOUBLE INJECTION IN GERMANIUM

Abstract

Some new features of the step‐voltage transient behavior of an electron‐hole plasma injected via contacts into a long bar of p‐type germanium are observed and explained theoretically. When the leading edge of the propagating plasma reaches the anode there is a cusp in the time derivative of the current, and thereafter the current increases with time essentially as constant x[1 ‐ exp (−t/τ)], where τ is the recombination time.
