Optical transitions and nature of Stokes shift in spherical CdS quantum dots
D. O. Demchenko, Lin-Wang Wang
We study the structure of the energy spectra along with the character of the states participating in optical transitions in colloidal CdS quantum dots (QDs) using the {\sl ab initi…
Photoluminescence pressure coefficients of InAs/GaAs quantum dots
Jun-Wei Luo, Shu-Shen Li, Jian-Bai Xia +1
We have investigated the band-gap pressure coefficients of self-assembled InAs/GaAs quantum dots by calculating 17 systems with different quantum dot shape, size, and alloying prof…
Calculating Quantum Transports Using Periodic Boundary Conditions
Lin-Wang Wang
An efficient new method is presented to calculate the quantum transports using periodic boundary conditions. This new method is based on a method we developed previously, but with…
Quantum Transport Calculations Using Periodic Boundary Conditions
Lin-Wang Wang
An efficient new method is presented to calculate the quantum transports using periodic boundary conditions. This method allows the use of conventional ground state ab initio progr…
Coulomb interaction in a quantum dot
Lin-Wang Wang
One approximation is made to describe a M+1 electron many-body wavefunction by a M electron many-body wavefunction and a single electron wavefunction. Under this approximation, we…
