First-principles study of the lattice and electronic structures of TbMnO
Chenjie Wang, Guang-Can Guo, Lixin He
The structural, electronic and lattice dielectric properties of multiferroic TbMnO are investigated using density functional theory within the generalized gradient approxim…
Electronic structure of self-assembled InAs/InP quantum dots: A Comparison with self-assembled InAs/GaAs quantum dots
Ming Gong, Kaimin Duan, Chuan-Feng Li +3
We investigate the electronic structure of the InAs/InP quantum dots using an atomistic pseudopotential method and compare them to those of the InAs/GaAs QDs. We show that even tho…
Direct observation of excitonic polaron in InAs/GaAs quantum dots
Ming Gong, Chuan-Feng Li, Geng Chen +7
Excitonic polaron is directly demonstrated for the first time in InAs/GaAs quantum dots with photoluminescence method. A new peak () below the ground state of exciton () com…
Ferroelectricity driven by the non-centrosymmetric magnetic ordering in multiferroic TbMn_2O_5: a first-principles study
Chenjie Wang, Guang-Can Guo, Lixin He
The ground state structural, electronic and magnetic properties of multiferroic TbMnO are investigated via first-principles calculations. We show that the ferroelectricity…
Calculation of near-field scanning optical images of exciton, charged excition and multiexciton wavefunctions in self-assembled InAs/GaAs quantum dots
Lixin He, Gabriel Bester, Zhiqiang Su +1
The near-field scanning optical microscopy images of excitonic wavefunctions in self-assembled InAs/GaAs quantum dots are calculated using an empirical pseudopotential method, foll…
