In 1 −xTlxP被认为是一种很有前途的红外探测器材料。在局域密度泛函理论中研究了一些关键的光学和结构性质。x=0.67时的In 1 −xTlxP和x=0.15时的In 1 −xTlxAs的带隙估计为0.1 eV。它们的结合能大于InSb，并且发现它们形成稳定的锌-锑合金。In 1 −xTlxP与InP几乎晶格匹配，并提供了集成探测器阵列和读出电路的潜力。
In1−xTlxP is proposed as a promising material for infrared detectors. A number of key optical and structural properties are studied within local density‐functional theory. In1−xTlxP at x=0.67 and In1−xTlxAs at x=0.15 are estimated to have a gap of 0.1 eV. Their binding energies are larger than that of InSb, and they are found to form stable zinc‐blende alloys for all x. In1−xTlxP nearly lattice matches to InP, and offers the potential to integrate detector array and read‐out circuit.
