Rough surface scattering in many‐mode conducting channels: gradient versus amplitude scattering
Rough surface scattering in many‐mode conducting channels: gradient versus amplitude scattering
We study the effect of surface scattering on transport properties in many-mode conducting channels (electron waveguides). Assuming a strong roughness of the surface profiles, we show that there are two independent control parameters that determine statistical properties of the scattering. The first parameter is the ratio of the amplitude of …
