Thermally Tunable Surface Acoustic Wave Cavities
André Luiz Oliveira Bilobran, Alberto García-Cristóbal, Paulo Ventura dos Santos +2
We experimentally demonstrate the dynamical tuning of the acoustic field in a surface acoustic wave (SAW) cavity defined by a periodic arrangement of metal stripes on LiNbO3 substr…
Topology driven g-factor tuning in type-II quantum dots
J. M. Llorens, V. Lopes-Oliveira, V. López-Richard +8
We investigate how the voltage control of the exciton lateral dipole moment induces a transition from singly to doubly connected topology in type II InAs/GaAsSb quantum dots. The l…
The generalized plane piezoelectric problem: Theoretical formulation and application to heterostructure nanowires
H. T. Mengistu, A. García-Cristóbal
We present a systematic methodology for the reformulation of a broad class of three-dimensional (3D) piezoelectric problems into a two-dimensional (2D) mathematical form. The sole…
Optical properties of wurtzite GaN/AlN quantum dots grown on non-polar planes: the effect of stacking faults in the reduction of the internal electric field
J. A. Budagosky, N. Garro, A. Cros +3
The optical emission of non-polar GaN/AlN quantum dots has been investigated. The presence of stacking faults inside these quantum dots is evidenced in the dependence of the photol…
LDA+U and tight-binding electronic structure of InN nanowires
A. Molina-Sánchez, A. García-Cristóbal, A. Cantarero +2
In this paper we employ a combined {\it ab initio} and tight-binding approach to obtain the electronic and optical properties of hydrogenated InN nanowires. We first discuss InN ba…
Finite Size Effects on the Optical Transitions in Quantum Rings under a Magnetic Field
Tatyana V. Bandos, Andres Cantarero, Alberto Garcia-Cristobal
We present a theoretical study of the energy spectrum of single electron and hole states in quantum dots of annular geometry under a high magnetic field along the ring axis in the…
Resonant hyper-Raman scattering in spherical quantum dots
E. Menendez-Proupin, C. Trallero-Giner, A. Garcia-Cristobal
A theoretical model of resonant hyper-Raman scattering by an ensemble of spherical semiconductor quantum dots has been developed. The electronic intermediate states are described a…
