AN AUGMENTED-SPACE RECURSIVE TECHNIQUE FOR THE CALCULATION OF ELECTRONIC-STRUCTURE OF RANDOM BINARY-ALLOYS

We present here a computationally feasible and fast technique for obta ining the electronic structure of random alloys which allows us to inc orporate effects like clustering, short-range order and off-diagonal d isorder arising out of size mismatch and consequent lattice distortion s. The method combines the augmented-space technique with the recursio n method and the tight-binding LMTO. AgPd alloys are studied to illust rate our procedure.
