Quantum Theory of Spontaneous Emission from Exciton-Electron-Phonon Complex in Solid: Quantum Interference and Many-Body Effect
Shi-Jie Xiong, S. J. Xu
A full quantum mechanical theory for the spontaneous emission from excitons simultaneously coupled to electronic excitations and anharmonic phonons in solid is developed. Origin of…

Temperature dependent photon emission spectra of free excitons in phonon field of GaN
S. J. Xu, G. Q. Li, S. -J. Xiong +1
Temperature-dependent radiative recombination of free excitons involving one or two LO phonons in GaN is investigated in detail. It is found that both phonon sidebands possess asym…

Experimental Observation of Kondo-Fano Resonant Tunneling in Silicon-Doped GaAs/AlAs Multiple Quantum Wells
S. J. Xu, S. -J. Xiong, J. Liu +2
We report experimental observation of Kondo-Fano resonant tunneling in Si-doped GaAs/AlAs multiple quantum wells. The spectrum of differential tunneling conductance at low bias sho…
