DOI: 10.1063/5.0204063

Abstract: We report on transport characteristics of field effect two-dimensional electron gases (2DEGs) in 24 nm wide indium arsenide surface quantum wells. High quality single-subband magnetotransport with clear quantized integer quantum Hall plateaus is observed to filling… read more here.

DOI: 10.1080/09500340.2017.1423410

Abstract: Abstract In this work, we consider the advantages and challenges of using free-standing two-dimensional electron gases (2DEG) as active components in atom chips for manipulating ultracold ensembles of alkali atoms. We calculate trapping parameters achievable… read more here.

DOI: 10.1103/physrevb.95.205101

Abstract: We describe a variational theory of multi-band two-dimensional electron gases that captures the interplay between electrostatic confining potentials, orbital-dependent interlayer electronic hopping and electron-electron interactions, and apply it to the d-band two-dimensional electron gases that… read more here.

DOI: 10.1126/sciadv.adp8208

Abstract: By introducing first-order quantum phases as topological invariants, recent symmetry analysis–based theories have reinvigorated magnetic quantum oscillations as a versatile quantum probe for unfolding the Fermi surface topology along with the geometry information, i.e., topo-Fermiology.… read more here.

DOI: 10.7567/1882-0786/ab512c

Abstract: We report a comparative study of the mobility of two-dimensional electron gases (2DEG) formed at AlGaN/GaN heterostructures by simultaneously growing on substrates with very different dislocation densities. The mobility is seen to depend on the… read more here.
