The electric and magnetic field effects on the energy spectrum, the charge distribution and the electric dipole moment induced by the electron released from an off-axis donor confined inside the thin shell layer is studied by using the double Fourier series expansion method. The density of states exhibits strongly marked Aharonov-Bohm oscillations induced by the magnetic field, while the electric field modifies the charge distribution. The average electron-donor distance increases slowly as the electric field increases from zero, but then it rises sharply as the electric field exceeds a threshold value forming a giant permanent dipole moment.

电场和磁场作用下核壳纳米线中的类氢供体

利用双傅里叶级数展开法研究了由薄壳层内部离轴供体释放出的电子所感应的电场和磁场对能谱，电荷分布和电偶极矩的影响。态密度显示出由磁场引起的强烈标记的阿哈罗诺夫-鲍姆振荡，而电场则改变了电荷分布。电子给体的平均距离随着电场从零开始缓慢增加，但随着电场超过阈值而急剧增加，从而形成巨大的永久偶极矩。
