Electronic properties of quantum-dot superlattices

Effect of electron–electron interactions in a quantum dot with a tapered constriction

“…A set of discrete states can be clearly associated with each region, identified by the locations of their well-localized charge distributions. These localized characteristics have also been implied in a calculation of an open quantum system [16]. Because the RHS is more confined than the LHS (Fig.…”

Low temperature magnetoresistance of GaAs/AiGaAs corrugated-gate wires

“…The wires are produced using a conventional split-gate geometry, in which one gate includes a corrugation that produces a set of coupled quantum dots in the wire [4,5]. In this paper, we discuss the geometry-induced transport behavior that occurs as a result of the corrugated-gate, which confines the trajectories of the electrons inside the wire.…”

Spin-polarization-dependent quantum transport through a quantum-dot array

“…For example, we can get the conductance of the devices from the transmission probability with the help of the Laudauer-Bu¨ticker formulas G ¼ ð2e 2 =hÞT, where e is the electron charge, h the Planck's constant, and T the transmission probability of the devices. Various methods have been developed for numerical calculations of the transmission probability T, such as mode-matching methods [7][8][9][10][11], recursive Green's function technique [12][13][14][15][16][17][18][19] and the scattering matrix [20].…”
