Disorderfree localization around the conduction band edge of crossing and kinked silicon nanowires
(A I P Publishing LLC, 2015)We explore ballistic regime quantum transport characteristics of oxideembedded crossing and kinked silicon nanowires (NWs) within a largescale empirical pseudopotential electronic structure framework, coupled to the ... 
Electronic and optical properties of 4.2 μm"N" structured superlattice MWIR photodetectors
(Elsevier, 2013)We report on the development of a new structure for type II superlattice photodiodes that we call the "N" design. In this new design, we insert an electron barrier between InAs and GaSb in the growth direction. The barrier ... 
HartreeFock approximation of bipolaron state in quantum dots and wires
(Springer, 2010)The bipolaronic ground state of two electrons in a spherical quantum dot or a quantum wire with parabolic boundaries is studied in the strong electronphonon coupling regime. We introduce a variational wave function that ... 
Landau levels in lattices with long  range hopping
(American Physical Society, 2013)Landau levels (LLs) are broadened in the presence of a periodic potential, forming a barrier for accurate simulation of the fractional quantum Hall effect using cold atoms in optical lattices. Recently, it has been shown ... 
Mn2+doped CdSe/CdS core/multishell colloidal quantum wells enabling tunable carrierdopant exchange interactions
(American Chemical Society, 2015)In this work, we report the manifestations of carrierdopant exchange interactions in colloidal Mn2+doped CdSe/CdS core/multishell quantum wells. The carriermagnetic ion exchange interaction effects are tunable through ... 
Pairing and vortex lattices for interacting fermions in optical lattices with a large magnetic field
(The American Physical Society, 2010)We study the structure of a pairing order parameter for spin1/2 fermions with attractive interactions in a square lattice under a uniform magnetic field. Because the magnetic translation symmetry gives a unique degeneracy ... 
qGaussian trial function in high density BoseEinstein condensates
(Elsevier Science B.V., 2003)We study the groundstate static properties of BoseEinstein condensates in the high density regime using a trial wave function of the form of a qGaussian. The flexibility afforded by a qGaussian trial function yields ... 
Time resolved photoluminescence study of magnetic CdSe/CdMnS/CdS core/multishell nanoplatelets
(SPIE, 2017)Colloidal semiconductor nanoplatelets (NPLs) are quasi 2Dnanostructures that are grown and processed inexpensively using a solution based method and thus have recently attracted considerable attention. We observe two ... 
Twoelectron singlet states in semiconductor quantum dots with Gaussian confinement: A singleparameter variational calculation
(Institute of Physics Publishing, 2007)The problem of two electrons in a threedimensional quantum dot with Gaussian confinement is investigated for the singlet pairing by a variational method with a very simple wavefunction containing only a single parameter ...
