摘要：

The effects of surface and quantum confinement on nano-LaFeO3 surface adsorbed by the sensor gas are probed by vacuum adsorptive surface photovoltage technique. The quantum confinement effect depends exponentially on the pressure of the sensor gas. There are two main ways of charge transfer transition on the adsorbed nano-LaFeO3 surface.
