摘要
Electron wavefunctions confined in a logarithmic potential well formed in the inversion layer of a metal oxide semiconductor field-effect transistor (MOSFET) are given on the basis of generalized Airy functions. The charge centroid of electrons in the inversion layer has been calculated to derive the quantum mechanical inversion-layer capacitance by taking into account higher subband states. It is shown that the present analytical model can quantitatively explain the experimentally observed inversion-layer capacitance.
