Abstract:	The band structures of (001), (111), and (110) InAs/GaSb superlattices in the semimetal regime are studied using a modified bond orbital model. The anti-crossing behavior between the sub-bands as well as the semiconductor-semimetal transition will be analyzed in detail, and is shown to be strongly dependent on the growth direction. The effects of interface hetero-bonds (In-Sb and Ga-As) on the InAs/GaSb superlattices are also discussed.
