Ap. Chernushich et al., MODULATION OF OPTICAL RADIATION BY REFLEC TION FROM A FILM STRUCTURE UNDER THE CONDITIONS OF EXCITATION OF AN INTERFACE POLARITON AT A METAL-SEMICONDUCTOR BOUNDARY, Kvantovaa elektronika, 21(10), 1994, pp. 949-951
A numerical calculation is reported of the reflection coefficient of a
plane electromagnetic wave incident on a multilayer asymmetry planar
metal-semiconductor structure, which forms a Schottky barrier at the i
nterface. The slope of the modulation characteristic of the reflection
coefficient is calculated for the case when the thickness of a deplet
ion layer in the contact region is controlled by an external voltage.
This slope is shown to be considerably less than the value reported by
other authors. An explanation is given of this discrepancy and method
s for increasing the slope of the modulation characteristic are sugges
ted.
