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…
Excitonic Polaron States and Fano Interference in Phonon-Assisted Photoluminescence of Bound Excitons in ZnO
Shi-Jie Xu, Shi-Jie Xiong, Shen-Lei Shi
We report a photoluminescence observation of robust excitonic polarons due to strong coupling of exciton and longitudinal optical (LO) phonon as well as Fano-type interference in h…
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…
Anti-Resonance and the 0.7 Anomaly in Conductance through a Quantum Point Contact
Ye Xiong, X. C. Xie, Shi-jie Xiong
We investigate the transmission of electrons through a quantum point contact by using a quasi-one-dimensional model with a local bound state below the band bottom. While the comple…
