从紧束缚模型出发 ,发现周期性排列的两种金属卤化物材料可以形成超晶格和多量子阱 (线 )结构 ,并进一步研究了这种新型结构的性质随单体材料势垒和势阱宽度的变化规律 ,发现由金属卤化物形成的周期性结构表现出明显的量子阱 (线 )特征 ,对掺杂电荷的约束作用也非常强 ,从而证明了可以研制和开发基于金属卤化物的多量子阱 (线 )材料与器件 Based on the tight-binding model, we found that the two metal halide materials with periodic arrangement can form superlattice and MQW structure, and the properties of the new structure are further studied with single material barrier and potential well The results show that the periodic structure formed by metal halide shows the obvious quantum well (line) characteristics and the strong constraint on the doping charge, which proves that it is feasible to develop and develop the multi-layer structure based on metal halide Quantum Well (Wire) Materials and Devices
