三体类正电子素激子复合物束缚态性质的质量依赖性
Mass-dependencies of the bound state properties for three-body positronium-like exitonic complexes
摘要：
本文研究了轻的双电子激子复合物（或团簇）$Z^{+} e^{-} e^{-}$中束缚态性质的质量依赖性，其中$m_e \le m_Z \le 2 m_e$。这些激子复合物（或模型离子）在现代固态物理中起着重要作用，因为这些复合物描述了许多半导体中的光吸收。我们还推导和测试了一些准确的质量插值公式，这些属性。一般来说，我们的质量插值公式允许人们预测（快速和准确）这些束缚态性质的数值在“新”激子复合物，即，在三体激子复合物与新的质量比。
英文摘要：
Mass-dependencies of a number of bound state properties are investigated in some light two-electron exitonic complexes (or clusters) $Z^{+} e^{-} e^{-}$, where $m_e \le m_Z \le 2 m_e$. These exitonic complexes (or model ions) play a great role in modern solid state physics, since such complexes describe optical absorption in a number of semiconductors. We also derived and tested a number of accurate mass-interpolation formulas for these properties. In general, our mass-interpolation formulas allow one to predict (fast and accurately) numerical values of these bound state properties in the `new' exitonic complexes, i.e., in three-body exitonic complexes with new mass ratios.
