摘要:
An optical image can be stored in the slow surface states of Ge and can be read out by the separated medium acoustoelectric effect with a surface wave on LiNbO3. It is found that the surface is sensitive to an optical pattern with optical power less than 1 &mgr;W/mm2at 368 nm wavelength. The memory time is considerably long due to the ’slow’ property of the surface states on Ge.
