金属纳米颗粒阵列与一维纳米线耦合的超晶格

It mainly studies the coupling of one-dimensional metal nanoparticle arrays with electrons in nanowire with the external laser field. The period potential is formed by the induced plasmonic excitations in the metal nanoparticle arrays. The potential field is coupled to the electrons in the nanowire, and this system can be thought of as a one-dimensional superlattice. The periodic potential and energy band structure of this system are theoretically calculated, and the influence of system parameters and electric field intensity on it is observed. It is found that the parameters such as the separation distance of metal nanoparticles and the intensity of the light field can significantly affect the energy band structure of the electron. Studying the behavior of electrons under periodic fields is an important part of condensed matter physics. The system constructed in this paper can easily adjust parameters and become a good platform for studying related phenomena.
