本文研究了高纯p型CdTe中两种不同的中性受主束缚激子复合物(Ag,X)和(Cu,X)的线性和二次塞曼效应。对于这两种复合物,结果是一致的束缚激子基态J= 1 - 2的Td对称性。相应的电子g值是电子的g e=− 1.77±0.02,空穴参数的K=+ 0.61±0.04和L=− 0.04±0.02分别描述了各向同性和各向异性的塞曼效应。观察到的中性受体束缚激子复合物的抗磁位移很好地解释了赝施主模型。
The linear and quadratic Zeeman effects have been studied for two different neutral-acceptor—bound-exciton complexes,(Ag, X) and (Cu, X), in high-purity p-type CdTe. For both complexes, the results are consistent with a bound-exciton ground state J= 1 2 in T d symmetry. The relevant electron g value is g e=− 1.77±0.02 for the electron, and K=+ 0.61±0.04 and L=− 0.04±0.02 for the hole parameters describing the isotropic and anisotropic Zeeman effects, respectively. The diamagnetic shift observed for the neutral-acceptor—bound-exciton complex is well explained in terms of the pseudodonor model.
