Electron transport in mesoscopic devices fabricated from indium antimonide/aluminum indium antimonide heterostructures grown by molecular beam epitaxy .
(2004)
Among all binary III-V semiconductors, InSb has the highest intrinsic electron mobility, the narrowest band gap, and the smallest electron effective mass (m* = 0.0139m0). These characteristics make InSb quantum wells (QWs) ...
Molecular beam epitaxy and characterization of indium antimonide/aluminum indium antimonide heterostructures.
(1998)
Two-dimensional electron systems were realized in InSb quantum wells with Al0.09In0.91Sb barrier layers delta-doped with Si. Measured electron mobilities in multiple quantum well structures grown on GaAs(001) substrates ...
Magneto-exciton and strain studies in indium antimonide quantum wells.
(2006)
The motivation for the exciton studies was based on interest in material characterization and study of the band structure of the InSb quantum wells. In this thesis, we have presented spectroscopic studies of InSb quantum ...
Quasi two-dimensional accumulation layer on n--type InAs in tipped magnetic fields /
(1984)
With the magnetic field parallel to the surface, non-periodic structure in the transconductance is observed and attributed to the total depopulation of the subbands as they are pushed up in energy above the Fermi level. ...
Fabrication and characterization of ordered arrays of nanostructures.
(2005)
In this thesis, a combination of bottom-up and top-down approaches is explored to fabricate ordered arrays of nanostrucutures. The bottom-up approach involves the growth of self-organized porous anodic aluminum oxide (AAO) ...
Intervalley Scattering in III-V Heterostructures and its Application to Valley Photovoltaic Hot Carrier Solar Cells
(2022-12-16)
The efficiency limit of 33% for a single gap solar cell is not fundamental. Mitigation of thermalization losses which occur when high energy ‘hot’ carriers are only extracted at the same energy as low energy carriers is a ...
Interaction effects in generalized Dirac systems
(2018-07)
Interaction effects in condensed matter systems with chiral quasiparticles at low energy are studied. A prominent example in the category of such systems is monolayer graphene, which has low energy massless Dirac excitations ...
Impurity scattering in a two-dimensional electron gas subject to a perpendicular magnetic field.
(1998)
We have calculated the Landau level (projected) Green's functions and the density of states of a two-dimensional electron gas in a perpendicular magnetic field as effected by impurity scattering using several different ...
