Photovoltaic displacement current in the piezoelectric semiconductor Bi12GeO20
Lazarev V. G., Fridkin V. M., Shlenskii A. L.
The displacement component of the bulk photovoltaic current was detected experimentally for the first time by measuring its Hall component in the magnetic field. The temperature and spectral dependences of the mobility of nonthermalized electrons in the piezoelectric semiconductor Bi12GeO20 were measured.
