  • 通过详尽的第一性原理计算, 提出了一类新型的二维III族金属硫族化合物MX (M = Al, Ga, In; X = S, Se, Te)的同素异形体. 这类化合物的结构是由正方形和八边形环构成的. 计算得到的结合能和声子谱表明, 所有的结构都同时具有能量和动力学稳定性. 所有结构都是间接带隙半导体, 其带隙大小随X原子由S到Se到Te的变化而减小. 计算结果表明这类材料具有很广的带隙范围, 从1.88到3.24 eV, 同时它们的能带结构可以通过双轴应变进一步调节. 这些结构具有丰富的电子结构性质和可调的带隙, 有可能被用于未来纳米电子学领域.
    Single-layered III-VI compounds have potential applications in many fields, such as highly sensitive photodetectors, field effect transistors, and electrochemical sensors, due to their wide range photosensitivities and excellent electronic properties. This paper presents a new two-dimensional tetragonal allotrope (called haeckelites structure) of single layered group III monochalcogenides MX (M = Al, Ga, In; X = S, Se, Te), which are constructed from the square and octagon rings. The first-principles calculations are performed using the Vienna ab initio simulation package (VASP) based on density functional theory (DFT). The cohesive energy of the haeckelite structure MX is positive and a little smaller than that (0.07—0.10 eV) of the hexagonal MX. The phonon spectra for the haeckelites structure MX have basically no imaginary frequencies in the whole Brillouin zone. The calculated binding energy and phonon spectrum show that these structures are energetically and dynamically stable. For all the compounds, the charge density isosurfaces show that most electrons are localized at the positions of X and M atoms, indicating that the M—X bond is ionic and M—M bond is covalent. All of haeckelite structure MX are indirect bandgap semiconductors, and their band gap sizes decrease with the X atom changing from S to Se to Te. For example, the band gaps of InS, InSe, and InTe are 2.42, 2.07, and 1.88 eV, respectively. The calculation results show that these materials have a wide band gap range from 1.88 to 3.24 eV. We find that the band gaps of AlS, AlSe, and GaS are relatively large with the values of 3.08, 3.03, and 3.24 eV, respectively. This may make them suitable for optically transparent devices. The band structures of GaSe, InS, InSe, and InTe can be further modulated by the biaxial strains. Their band gaps decrease linearly with the strain increasing. The band gap of AlS and AlSe both first increase and then decrease with the strain increasing.
