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