Frequency as a Clock: Synchronization and Intrinsic Recovery in Graphene Transistor Dynamics
Victor Lopez-Richard, Igor Ricardo Filgueira e Silva, Gabriel L. Rodrigues +4
Hysteresis and memory effects in graphene field-effect transistors (GFETs) offer unique opportunities for neuromorphic computing, sensing, and memory applications, yet their physic…
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…
Graphene Heterostructure-Based Non-Volatile Memory Devices with Top Floating Gate Programming
Gabriel L. Rodrigues, Ana B. Yoshida, Guilherme S. Selmi +7
We present a graphene-based memory platform built on dual-gated field-effect transistors (GFETs). By integrating a lithographically defined metal patch directly atop the hexagonal…
Two-dimensional talc as a natural hyperbolic material
Flávio H. Feres, Francisco C. B. Maia, Shu Chen +14
This study demonstrates that two-dimensional talc, a naturally abundant mineral, supports hyperbolic phonon-polaritons (HPhPs) at mid-infrared wavelengths, thus offering a low-cost…
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…
