Abstract
Summary form only given.Summary from only given. Recently the GaAs multiple quantum well (MQW) transverse-field structures were investigated by means of DC photo-EMF effect, which is excited by moving interference pattern at /spl lambda/=1064 nm. Below we present the first results on investigation of similar and longitudinal-filed structures by means of alternating photo-EMF currents (excited by vibrating interference pattern) at shorter wavelengths, which ensure efficient generation of photocarriers of both types.
