量子棒中极化子基态能量的杂质效应
Impurity Effects of Ground State Energy of Polaron in Quantum Rods
摘要
Abstract
The Hamiltonian of a quantum rod with an ellipsoidal boundary is given after a coordinate transformation that changes the ellipsoidal boundary into a spherical one.We then study the ground state energy of the weak-coupled impurity polaron in a quantum rod.The effects of the ellipsoid aspect ratio,the transverse and the longitudinal effective confinement lengths,the Coulomb bound potential and the electron-phonon coupled strength are taken into consideration by using the linear combination operator method.It is found that the ground state energy will increase rapidly with decreasing confinement lengths.These can be attributed to the interesting quantum size confining effects.The ground state energy is a decreasing functions of the Coulomb bound potential,the ellipsoid aspect ratio and the electron-phonon coupled strength.关键词
