Laser-dressed-band approach to shallow-impurity levels of semiconductor heterostructures
(Pergamon-elsevier Science LtdOxfordInglaterra, 1998)
Influence of nonmagnetic impurity scattering on spin dynamics in diluted magnetic semiconductors
(American Physical Society, 2017-01)
The doping of semiconductors with magnetic impurities gives rise not only to a spin-spin interaction between quasifree carriers and magnetic impurities but also to a local spin-independent disorder potential for the carriers. ...
Influence of the spin-orbit interaction in the impurity-band states of n-doped semiconductors
(Elsevier Science, 2012-08)
We study numerically the effects of an extrinsic spin-orbit interaction on the model of electrons in n-doped semiconductors of Matsubara and Toyozawa (MT). We focus on the analysis of the density of states (DOS) and the ...
Laser dressing effects in low-dimensional semiconductor systems
(Pergamon-elsevier Science LtdOxfordInglaterra, 2000)
Spin-relaxation time in the impurity band of wurtzite semiconductors
(American Physical Society, 2017-09-18)
The spin-relaxation time for electrons in the impurity band of semiconductors with wurtzite crystal structure is determined. The effective Dresselhaus spin-orbit interaction Hamiltonian is taken as the source of the spin ...
Magnetic field effects on donor transitions in quantum wells
(Pergamon-elsevier Science LtdOxfordInglaterra, 1996)
Substitutional Ta-doping in Y2O3 semiconductor by sol-gel synthesis: Experimental and theoretical studies
(IOP Publishing, 2017-07)
The Pechini sol-gel method has been employed for the synthesis of pure and (181Hf→)181Ta-doped Y2O3 nanopowders. We performed a structural characterization from the micro to the subnanoscopic scale by means of scanning ...
Finite-difference calculation of donor energy levels in a spherical quantum dot subject to a magnetic field
(Elsevier B.V., 2015-02-01)
The ground and excited states of a donor impurity at the center of a spherical quantum dot subject to a magnetic field are calculated within the effective-mass approximation. The barriers are infinitely high and the ...
