Statistical Disorder in MBE-Grown AlGaAs/GaAs Superlattices for Quantum Bragg Mirrors using Synchrotron X-ray Diffraction
Mateus T. Souza, Germano M. Penello, Guilherme A. Calligaris +1
AlGaAs/GaAs superlattices grown by Molecular Beam Epitaxy (MBE) are foundational for advanced optoelectronic devices, including Quantum Bragg Mirror (QBM) infrared detectors. The p…
Periodic strings: a mechanical analogy to photonic and phononic crystals
R. S. Pitombo, M. Vasconcellos, P. P. Abrantes +3
We study a periodic vibrating string composed of a finite sequence of string segments connected periodically, with each segment characterized by a constant linear mass density. The…
Ion-beam modification of the magnetic properties of GaMnAs epilayers
E. H. C. P. Sinnecker, G. M. Penello, T. G. Rappoport +5
We study the controlled introduction of defects in GaMnAs by irradiating the samples with energetic ion beams, which modify the magnetic properties of the DMS. Our study focuses on…
