利用精确对角化方法,研究了抛物势双层量子点中带负电荷激子的1S态和3P态的关联能与量子点的束缚势大小的变化关系,以及1S态对应几个不同的量子点间点与点的距离的束缚能随束缚势大小的变化关系,计算了电子与空穴质量比为σ=0.677和σ=0.197的缚能随束缚势大小的变化关系. Using the accurate diagonalization method, the relationship between the bond energies of the 1S state and the 3P state of a negatively charged exciton in a parabolic double-layered quantum dot and the binding energy of a quantum dot is studied, and several different quantum states corresponding to the 1S state The bound of the distance between the point and the point can be calculated as the relationship between the bound energy of the binding energy with the mass ratio of electron to the hole of σ = 0.677 and σ = 0.197 with the variation of the bound potential.
