Orbital magnetic properties of quantum dots: the role of electron-electron interactions
L. G. G. V. Dias da Silva, Caio H. Lewenkopf, Nelson Studart
We study the magnetic orbital response of a system of N interacting electrons confined in a two-dimensional geometry and subjected to a perpendicular magnetic field in the finite t…
Intersubband plasmons in quasi-one-dimensional electron systems on a liquid helium surface
Marcos R. S. Tavares, G. -Q. Hai, F. M. Petters +1
The collective excitation spectra are studied for a multisubband quasi-one-dimensional electron gas on the surface of liquid helium. Different intersubband plasmon modes are identi…
Electron-phonon interaction in quantum-dot/quantum-well semiconductor heterostructures
F. Comas, Nelson Studart
Polar optical phonons are studied in the framework of the dielectric continuum approach for a prototypical quantum-dot/quantum-well (QD/QW) heterostructure, including the derivatio…
Magnetoresistance of nondegenerate quantum electron channels formed on the surface of superfluid helium
Yu. P. Monarkha, S. S. Sokolov, G. Q. Hai +1
Transport properties of quasi-one-dimensional nondegenerate quantum wires formed on the surface of liquid helium in the presence of a normal magnetic field are studied using the mo…
