Abstract
Appearance of a transverse photocurrent at local excitation, by an optical beam, of the surface of n-p-n-structure realized on the basis of a two-dimensional electron gas is studied theoretically. It is shown that the magnitude and sign of the photocurrent depend on the coordinate of the center of light spot. Conditions of linearity of this dependence are found demonstrating the suitability of two-dimensional bipolar structures for use in position-sensitive detectors with high spatial resolution.
