Abstract:In this thesis, we investigate the control of the hyperfine interaction between a conduction electron and a P-impurity nuclear spin in a symmetric metal-oxide semiconductor structure with face-to-face gate oxide layers. We solve the Poisson equation for the device electronics and the Schrodinger equation for the quantum states in the Si - layer by taking into account the nonisotropic effective mass of silicon at each of the six degenerate minima in the conduction band. It is shown that the double gate device leads to better performance, in terms of higher wave function amplitude modulation and consequently higher nuclear magnetic resonance frequency compared to single gate devices for relatively short impurity distances from the oxide layers.
