Probing Interface-Driven Mechanisms of Non-Classical Light in van der Waals Heterostructures
Bárbara L. T. Rosa, Lara Greten, Raphaela de Oliveira +7
Single-photon emitters in two-dimensional semiconductors offer a versatile platform for integrated quantum photonics, yet their performance is strongly influenced by local dielectr…
Correlative Analysis of Iron-Driven Structural, Optical, and Magnetic Properties in Natural Biotite Crystals
Raphaela de Oliveira, Yara Galvão Gobato, Ronei C. de Oliveira +9
Biotite crystals are phyllosilicate trioctahedral micas with the general chemical formula K(Mg,Fe)3AlSi3O10(OH)2 that form a solid-solution series with iron-poor phlogopite and iro…
Interplay of energy and charge transfer in WSe2/CrSBr heterostructures
José Roberto de Toledo, Caique Serati de Brito, Barbara L. T. Rosa +12
Van der Waals heterostructures (vdWHs) composed of transition-metal dichalcogenides (TMDs) and layered magnetic semiconductors offer great opportunities to manipulate exciton and v…
Charge transfer and asymmetric coupling of MoSe valleys to the magnetic order of CrSBr
C. Serati de Brito, P. E. Faria Junior, T. S. Ghiasi +13
Van der Waals (vdW) heterostructures composed of two-dimensional (2D) transition metal dichalcogenides (TMD) and vdW magnetic materials offer an intriguing platform to functionaliz…
Phyllosilicates as earth-abundant layered materials for electronics and optoelectronics: Prospects and challenges in their ultrathin limit
Ingrid D. Barcelos, Raphaela de Oliveira, Gabriel R. Schleder +10
Phyllosilicate minerals are an emerging class of naturally occurring layered insulators with large bandgap energy that have gained attention from the scientific community. This cla…
Distinctive g-factor of moire-confined excitons in van der Waals heterostructures
Y. Galvão Gobato, C. Serati de Brito, Andrey Chaves +7
We investigated experimentally the valley Zeeman splitting of excitonic peaks in the photoluminescence (PL) spectra of high-quality hBN/WS2/MoSe2/hBN heterostructures at near-zero…
Experimental evidences of trions and Fermi edge singularity in single barrier GaAs/AlAs/GaAs heterostructure using photocapacitance spectroscopy
Amit Bhunia, Mohit Kumar Singh, Y. Galvao Gobato +2
In this paper, we show how photocapacitance spectra can probe two dimensional excitonic complexes and Fermi edge singularity as a function of applied bias around 100 K. In lower de…
Experimental evidences of quantum confined 2D indirect excitons in single barrier GaAs/AlAs/GaAs heterostructure using photocapacitance at room temperature
Amit Bhunia, Mohit Kumar Singh, Y. Galvao Gobato +2
We investigated excitonic absorptions in GaAs/AlAs/GaAs single barrier heterostructure using both photocapacitance and photocurrent spectroscopies at room temperature. Photocapacit…
Aharonov-Bohm interference in quantum ring exciton: effects of built-in electric fields
M. D. Teodoro, V. L. Campo, V. Lopez-Richard +10
We report a comprehensive discussion of quantum interference effects due to the finite structure of excitons in quantum rings and their first experimental corroboration observed in…
Electric field inversion asymmetry: Rashba and Stark effects for holes in resonant tunneling devices
H. B. de Carvalho, M. J. S. P. Brasil, V. Lopez-Richard +7
We report experimental evidence of excitonic spin-splitting, in addition to the conventional Zeeman effect, produced by a combination of the Rashba spin-orbit interaction, Stark sh…
