摘要:
We examine the effects of like atom bonds on the electronic density of states (DOS) of amorphous binary compounds. This is done explicitly using the empirical pseudopotential method to study various complex crystalline structures with different fractions of like‐atom bonds distributed in varying configurations. Our results show marked differences in the regions in the DOS that are most affected by like‐atom bonds. In particular we sketch the DOS of a typical amorphous system with 10% like‐atom bonds and show a plot of the charge density of a like and unlike atom bond.
