Abstract

Abstract:

The variation of the energy for the ground states of single electron concentric quantum ring with its radius and potential barrier was obtained, which was analyzed via dynamics and uncertainty relation. Electronic probability distribution of the ground states was demonstrated via the density functions. The result indicates that when the ground\|state energy is less than the potential barrier, electronic probability in the potential barrier is not zero.

Key words: concentric quantum ring, ground state, energy, probability
