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…
Electrical manipulation of intervalley trions in twisted MoSe homobilayers at room temperature
Bárbara L. T. Rosa, Paulo E. Faria Junior, Alisson R. Cadore +6
The impressive physics and applications of intra- and interlayer excitons in a transition metal dichalcogenide twisted-bilayer make these systems compelling platforms for exploring…
Optical memory in a MoSe/Clinochlore device
Alessandra Ames, Frederico B. Sousa, Gabriel A. D. Souza +10
Two-dimensional heterostructures have been crucial in advancing optoelectronic devices utilizing van der Waals materials. Semiconducting transition metal dichalcogenide monolayers,…
Ultrathin natural biotite crystals as a dielectric layer for van der Waals heterostructure applications
Raphaela de Oliveira, Ana Beatriz Yoshida, Cesar Rabahi +5
