摘要

The sampe was a silicon glass with conducting films (ITO) evaporated by reactive ion sputtering on its both slides. The internal electric field was created by applying a negative polarizing voltage U_(pol) to field electrode. The investigations wer performed in the vacuum of the order 10~(-6)Pa. As a result of applying U_(pol) and illumination, photoelectrons are released and enter electron multiplier. The electrons create voltage pulses in the multiplier which are recorded in the multichannel pulse amplitude analyzer. The amplitude spectra were mesured for unilluminated samples and illuminated by a quartz lamp.
