| 摘 要： | 用线性组合算符法、LLP变换法和量子统计的方法,研究了温度对磁场中抛物量子点内弱耦合磁极化子的影响,得到了磁极化子基态能量和基态束缚能量与量子点的受限强度、回旋频率和温度的依赖关系。数值计算结果表明,磁极化子的基态束缚能量 Eb 随回旋频率ωc的增加而增大,随温度参量γ的增加而减小, Eb 随γ的增加而减小的幅度,不仅与γ的取值范围有关,而且还与ωc有显著关系, Eb 显著变化的γ范围随ωc的增加而减小。

| Abstract: | Quantum dot system has attracted a lot of attention as a possible candidate for the parts of an apparatus of quantum function,due to the potential applications foreground and a great deal of novel optoelectronic and transport properties.But owing to the research of electronic properties in quantum dot being very important,so more and more researchers started to study the quantum dot properties both theoretically and experimentally.However,for the convenience,in those works,people only confine themselves to ... |
