| 内容記述 | Recently, Goto et al. have discovered the anomalous elastic softening due to vacancy in crystalline silicon in the low-temperature ultrasonic measurements. To investigate the quantum state of the silicon vacancy, we introduce a cluster model which includes both the Coulomb interaction between electrons in the dangling bond and the coupling between the electrons and Jahn-Teller phonons. We solve the model by using the numerical diagonalization method and find that the V + state which has spin S = 1/2 is stable with the trigonal mode phonon while unstable with the tetragonal mode phonon. The obtained result is consistent with the newly observed experiment. | |||||
