Nanoscale science and technology is a young and burgeoning field that encompasses
nearly every discipline of science and engineering. With rapid advances in areas such as …

In quantum-dot laser devices containing a quasi-two-dimensional wetting layer, a pump
process initially populates the wetting-layer states. The scattering of carriers from these …

Coulomb correlations in the optical spectra of semiconductor quantum dots are investigated
using a full-diagonalization approach. The resulting multi-exciton spectra are discussed in …

The hole system in InAs quantum dots was investigated by frequency-dependent
capacitance–voltage spectroscopy. Up to eight distinct charging peaks could be observed …

通过有效质量近似和变分法, 研究了垂直磁场下透镜型量子点中类氢杂质基态能量,

A general method for evaluating the energy levels and wavefunctions of symmetroidal
quantum dots is proposed, via solving the three-dimensional time-independent Schrödinger …

We investigated theoretically the effects of the one-dimensional barriers on the electronic
states in a quantum dot grown on a nonplanar substrate. These peculiar barriers drastically …

We have studied the single-electron and two-electron vertically assembled quantum disks in
an axial magnetic field using the effective mass approximation. The electron interaction is …

The concept of dynamical symmetries is specified for quantum dots under strong Coulomb
blockade. It is shown that the electron cotunneling through quantum dots may be described …

We report on an optical study of excited states in single CdTe quantum dots (QDs). Micro-
photoluminescence excitation (μPLE) measurements first reveal the existence of confined …
