The directional properties in coupled MOS channels are studied using a non-equilibrium Green's function (NEGF) method coupled with Poisson equation for self-consistency. Acoustic scattering and lowest order inter-valley optical scattering are included through self-energy terms in Green's function. The simulations show that, by changing the voltage on control gates, carrier conductance can be switched from one channel to the other with an on/off ratio of up to ≈ 105.
