THE EMA FOR A 2-BAND SPATIALLY DISORDERED SYSTEM - COMPARISON OF SIMULATION WITH THEORY

Abstract:
An approximate but soluble single-site theory for the density of states of a two-band spatially disordered system, the single super-chain approximation/effective-medium approximation (SSCA/EMA), is compared with direct simulations on and off-diagonally disordered, two-level tight-binding model. The theory reproduces the simulations remarkably well.
