Sweeney, V and Burbridge, C R and Leadbeater, M and Lambert, C J (1996) Theory of geometry induced quantum transport. Czechoslovak Journal of Physics, 46 (s5). pp. 2515-2516. ISSN 0011-4626Full text not available from this repository.
We present theoretical results for the geometry-dependence of the electrical conductance of a phase-coherent two-dimensional electron gas (2DEG). As an example, we examine a staircase-shaped 2DEG formed from a periodic array of rectangular cells joined near their corners and compare the differential conductance G(E) at voltage V, with the density of states N(E) at energy E = eV. By evaluating the multi-channel Landauer formula, we demonstrate that near the band tails, geometry-induced structure persists, even in the presence of disorder.*
