Charge control in laterally coupled double quantum dots
American Physical Society (2011-07-27)We investigate the electronic and optical properties of InAs double quantum dots grown on GaAs (001) and laterally aligned along the [110] crystal direction. The emission spectrum has been investigated as a function of a ... -
Electrons, holes, and excitons in GaAs polytype quantum dots
American Institute of Physics (2016)Single and multi-band k⋅p Hamiltonians for GaAs crystal phase quantum dots are used to assess ongoing experimental activity on the role of such factors as quantum confinement, spontaneous polarization,valence band mixing, ... -
Origin of two-hole triplet splitting in circular quantum dots
Elsevier (2012-05)Recent photoluminescence spectra of positively charged excitons in InAs/GaAs quantum dots have revealed the existence of large splittings between the View the MathML sourcep-shell triplet sublevels of holes. We provide an ... -
Quantum mechanical modeling of excited electronic states and their relationship to cathodoluminescence of BaZrO3
American Institute of Physics (AIP Publishing LLC) (2013)First-principles calculations set the comprehension over performance of novel cathodoluminescence (CL) properties of BaZrO3 prepared through microwave-assisted hydrothermal. Ground (singlet, s*) and excited (singlet s** ... -
Two-dimensional Bloch electrons under strong magnetic modulation
American Physical Society (2011-01-13)The band structure of a high-mobility two-dimensional electron gas patterned with a square lattice of holes (antidots) is studied theoretically under the influence of a magnetic modulation consisting of perpendicular ...
