J. Pultorak et al., INFLUENCE OF THE CURRENT-DENSITY AND INTERNAL ELECTRIC-FIELD ON THE EXCLUSION OF EXCESS CARRIERS IN LONG SEMICONDUCTOR SAMPLES, Semiconductor science and technology, 10(4), 1995, pp. 395-404
Long, exponentially inhomogeneous germanium structures with two l-h ju
nctions are used as modulators of infrared radiation working in the ex
clusion regime. An analysis of excess current carrier transport in the
se structures in conditions of an internal electric field is given. Ty
pical distributions of excess carriers and current-voltage characteris
tics are calculated and presented.
