Experimental analysis of charge carrier equilibration and distribution in silicon inside MOSFET using surface photovoltage spectroscopy (SPS)
Abstract
The charge carrier equilibration and distribution in silicon inside MOSFET was analyzed using surface photovoltage spectroscopy (SPS). Chemically treating the surface resulted to not well-defined states and transitions, and thus, keeping the samples under the dark after illumination with intense white light made the samples more responsive to illuminating light. Moreover, from the results obtained, the MOS structure of MOSFETs can be used as an alternative to the conventional Kelvin probe method in doing SPS analysis.
