Subject RIV: BM - Solid Matter Physics ; Magnetism

SI GaAs based photodetectors were studied by photocurrent and current-voltage methods. Features observed in photocurrent spectra of the detectors with Gd top contact indicate special properties of this kind of the metallization and, possibly, a formation of 2D system near the contact.
