摘要: In the framework of the effective mass theory, this paper calculates the electron energy levels of an InAs/GaAs tyre-shape quantum ring (TSQR) by using the plane wave basis. The results show that the electron energy levels are sensitively dependent on the TSQR's section thickness $d$, and insensitively dependent on TSQR's section inner radius $R_1$ and TSQR's inner radius $R_2$. The model and results provide useful information for the design and fabrication of InAs/GaAs TSQRs.
