Polarization-sensitive photoresponse of the CuSe/Se nanocomposite prepared by vacuum thermal deposition

•The CuSe/Se bilayer consisting of nanocrystalline CuSe and amorphous Se films was synthesized.•Polarization dependent photocurrent was observed in the CuSe/Se bilayer irradiated with femtosecond laser pulses.•It was found that the photoresponse of the CuSe/Se bilayer is helicity sensitive.•The polarization-sensitive photoresponse of the CuSe/Se bilayer originates from the surface photogalvanic effect.
