Structural, magnetic, and nanoacoustic characterization of Co/Pt superlattices
E. R. Cardozo de Oliveira, C. Xiang, C. Borrazás +7
Superlattices presenting a spatial modulation of the elastic properties appear as a main tool to reach the THz regime in nanoacoustic devices. The exploration of alternative materi…
Elliptical micropillars for efficient generation and detection of coherent acoustic phonons
Chushuang Xiang, Anne Rodriguez, Edson Rafael Cardozo de Oliveira +5
Coherent acoustic phonon generation and detection assisted by optical resonances are at the core of efficient optophononic transduction processes. However, when dealing with a sing…
Effects of surface roughness and top layer thickness on the performance of Fabry-Perot cavities and responsive open resonators based on distributed Bragg reflectors
Konstantinos Papatryfonos, Edson Rafael Cardozo de Oliveira, Norberto Daniel Lanzillotti-Kimura
Optical and acoustic resonators based on distributed Bragg reflectors (DBRs) hold significant potential across various domains, from lasers to quantum technologies. In ideal condit…
Topological Nanophononic Interface States Using High-Order Bandgaps in the One-Dimensional Su-Schrieffer-Heeger Model
Anne Rodriguez, Konstantinos Papatryfonos, Edson Rafael Cardozo de Oliveira +1
Topological interface states in periodic lattices have emerged as valuable assets in the fields of electronics, photonics, and phononics, owing to their inherent robustness against…
Perspectives on high-frequency nanomechanics, nanoacoustics, and nanophononics
Priya, Edson R. Cardozo de Oliveira, Norberto D. Lanzillotti-Kimura
Nanomechanics, nanoacoustics, and nanophononics refer to the engineering of acoustic phonons and elastic waves at the nanoscale and their interactions with other excitations such a…
Probing Gigahertz Coherent Acoustic Phonons in TiO Mesoporous Thin Films
E. R. Cardozo de Oliveira, C. Xiang, M. Esmann +7
Ultrahigh-frequency acoustic-phonon resonators usually require atomically flat interfaces to avoid phonon scattering and dephasing, leading to expensive fabrication processes, such…
Spin dependent analysis of homogeneous and inhomogeneous exciton decoherence in magnetic fields
V. Laurindo, E. D. Guarin Castro, G. M. Jacobsen +9
This paper discusses the combined effects of optical excitation power, interface roughness, lattice temperature, and applied magnetic fields on the spin-coherence of excitonic stat…
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…
Type II InAs/GaAsSb Quantum Dots: Highly Tunable Exciton Geometry and Topology
José M. Llorens, Lukasz Wewior, Edson R. Cardozo de Oliveira +5
External control over the electron and hole wavefunctions geometry and topology is investigated in a p-i-n diode embedding a dot-in-a-well InAs/GaAsSb quantum structure with type I…
Thermal Effects on Photon-Induced Quantum Transport
M. O. Assunção, E. J. R. de Oliveira, J. M. Villas-Bôas +1
We theoretically investigate laser induced quantum transport in a two-level quantum dot attached to electric contacts. Our approach, based on nonequilibrium Green function techniqu…
A semiquantitative approach to the impurity-band-related transport properties of GaMnAs nanolayers
E. J. R. de Oliveira, E. Dias Cabral, M. A. Boselli +1
We investigate the spin-polarized transport of GaMnAs nanolayers in which a ferromagnetic order exists below a certain transition temperature. Our calculation for the self-averaged…
