Abstract
In1-xTlxSb is proposed as promising infrared material. A number of opt ical and structural properties are studied within local density-functi onal theory. The alloy at x = 0.09 is estimated to have a gap of 0.1 e V. Although T1Sb is found to favor the CsCl structure, the zinc blende alloy is stable for low x values. A phase diagram is calculated to es timate the regions of stable phases and explore the conditions for gro wing narrow-gap In1-xTlxSb alloys.
