  • 确立了柱状纳米系统电子势能随距离的变化关系,以HgS/CdS/HgS柱状纳米系统为例,讨论了层间作用对电子能谱的影响.结果表明:电子能量随势垒宽度和波矢的增大而增大,随势阱宽度的增大而减小;层间互作用会增大电子能量,但不会改变电子能量随势阱和势垒以及波矢的变化趋势.
    The variation of the electronic energy in a columnar nanometer system with the i ncrease of radius is established, and the HgS/CdS/HgS nanometer system is used to discuss the influence of the layer_to_layer interaction energy on the electr onic energy spectrum of electrons. Some important results indicate that the ene rgy of the electronic energy increases with the increase of the potential barrie r width and the wave vector, while the potential well width and the layer_to_la yer interaction energy makes the electronic energy larger, but it doesn't effec t the variation of electronic energy with the potential well width, potential ba rrier or the wave vector.
