摘要 利用精确对角化方法计算了外加磁场下类氢施主杂质量子点中的激子的束缚能,发现系统的束缚能随着量子点的束缚势的增大而减小,随着外加磁场的增大而减小. An investigation of exciton under magnetic field indicate with inc that the binding ene binding energy of a hydrogenic donor in a parabolic quantum dot with is calculated by using the matrix diagonalization method. The results rgy decreases with increasing confinement strength and also decreases reasing the magnetic field strength.
