Energy band mismatch

Webthe computer program corrected the mismatch between the curves, allowing the extraction of correct data of the interface states density distribution as a function of the energy along the silicon bandgap. 1. Introduction The analysis of the high and low frequency capacitance-voltage curves is a traditional way to WebQuite simply, recombination occurs when electrons in the conduction band fill holes in the valence band. As a result, a kind of “no carrier's land” or so-called space charge region is created. It is also known as a depletion region, because both the mobile electrons and holes are depleted within it.
