Abstract
In1−xTlxSb is proposed as promising infrared material. A number of optical and structural properties are studied within local density‐functional theory. The alloy at x=0.09 is estimated to have a gap of 0.1 eV. Although TlSb is found to favor the CsCl structure, the zinc blende alloy is stable for low x values. A phase diagram is calculated to estimate the regions of stable phases and explore the conditions for growing narrow‐gap In1−xTlxSb alloys.Keywords
