Abstract

We describe the influence of hard-wall confinement and lateral dimension on the low-temperature transport properties of long diffusive channels and ballistic crosses fabricated in an InSb/In1-xAlxSb heterostructure. Partially diffuse boundary scattering is found to play a crucial role in the electron dynamics of ballistic crosses and substantially enhance the negative bend resistance. Experimental observations are supported by simulations using a classical billiard ball model for which good agreement is found when diffuse boundary scattering is included.
