Symmetry Constraints and the Electronic Structures of a Quantum Dot with Thirteen Electrons
G. M. Huang, Y. M. Liu, C. G. Bao
Abstract
The symmetry constraints imposing on the quantum states of a dot with 13 electrons has been investigated. Based on this study, the favorable structures (FSs) of each state has been identified. Numerical calculations have been performed to inspect the role played by the FSs. It was found that, if a first-state has a remarkably competitive FS, this FS would be pursued and the state would be crystal-like and have a specific core-ring structure associated with the FS. The magic numbers are found to be closely related to the FSs.
