WebWhen the potential V s is equal to 2 F, V G = V T the inversion regime starts, i.e. the Si surface becomes to have a n-type behavior rather than a p-type one. Such a behavior is enhanced as the flat band voltage is increased. In the inversion regime the WebCorrelation between the flat band potential and electron affinity of semiconductors: (1) equation including the effect of the solvent donor numbers
