چکیده

Spin density functional theory is used to calculate the ground state electronic structures of circular parabolic quantum dots. We find that such dots either have a spin configuration determined by Hund’s rule or make a spin-density-wave-like state with zero total spin. The dependence of the spin-density-wave amplitudes on the density of the two-dimensional electron gas is studied. [S00319007(97)03740-X]

Spin-Density-Functional Theory of Circular and Elliptical Quantum Dots

Using spin-density-functional theory, we study the electronic states of a two-dimensional parabolic quantum dot with up to N = 58 electrons. We observe a shell structure for the filling of the dot with electrons. Hund’s rule determines the spin configuration of the ground state, but only up to 22 electrons. At specific N , the ground state is degenerate, and a small elliptical deformation of th...

Vertically coupled quantum dots in the local spin-density functional theory

We have investigated the structure of double quantum dots vertically coupled at zero magnetic field within local-spin-density functional theory. The dots are identical and have a finite width, and the whole system is axially symmetric. We first discuss the effect of thickness on the addition spectrum of one single dot. Next we describe the structure of coupled dots as a function of the interdot...

Exact diagonalization and Quantum Monte Carlo studies of quantum dots

We report exact diagonalization and diffusion quantum Monte Carlo calculations of quantum dots (QDs) in which energetics due to electron-electron interactions, magnetic field, and geometrical factors compete and induce interesting ground state configurations. The geometrical effects are generated by different confining potentials such as parabolic shaped, ring shaped, and disordered potentials....

Addition Energy Spectra of Semiconductor Quantum Dots

Advances in the semiconductor technologies allow the realization of quantum dot structure in which a finite number of electrons are confined by an artificial potentials [1–3]. The number of electrons in a quantum dot, denoted N , which can also be controlled experimentally, affects many physical properties of the quantum dot. By changing the quantum dot size and the number of electrons, far-inf...
