关键词:
摘要: It is shown that a metallic state can be induced on the surface of SrTiO3 crystals by electron beam evaporation oxygen deficient alumina or insulating granular aluminium. No special preparation nor heating needed. Final states obtained depending pressure during process. Photoconductivity and electrical field effect are also demonstrated.
