  "abstract": "Electronic transport through a 2D deca-nanometer length channel with correlated and anti-correlated surfaces morphologies is studied using the Keldysh non-equilibrium Green function technique. Due to the pseudo-periodicity of these structures, the energy-resolved transmission possesses pseudo-bands and pseudo-gaps. Channels with correlated surfaces exhibit wider pseudo-bands than their anti-correlated counterparts. By surveying channels with various combinations of material parameters, we found that a smaller transport mass increases the channel transmittivity and energy bandwidth of the pseudo-bands. A larger quantization mass yields a larger transmittivity in channels with anti-correlated surfaces. For channels with correlated surfaces, the dependence of transmittivity on quantization mass is complicated by odd-to-even mode transitions. An enhanced threshold energy in the energy-resolved transmission can also be observed in the presence of surface roughness. The computed enhanced threshold energy was able to achieve agreement with the experimental data for Si[110] and Si[100] devices.",
