Electronic Structure of Zinc-Blende CdS Quantum Dots:A New Approach Under Tight-Binding Approximation*
摘要
Abstract
We have developed a new approach to calculate the electronic structure of zinc-blend CdS quantum dots under the frame of tight-binding approximation (TBA), which is compared with the effective mass approximation (EMA). This approach is rather concise because the calculation is performed in K-space instead of in real space, but the results are justified by the results calculated in real space. The TBA theoretical results could give good explanation of the experimental data over a large range. Our results demonstrate that the method of calculation in K-space is simple and effective, which can be extended to other materials with different structure.关键词
