Optical Gain Through Metallic Electro-Optical Effects
N. Roldan-Levchenko, D. J. P. de Sousa, C. O. Ascencio +3
Optical gain is a critical process in today's semiconductor technology and it is most often achieved via stimulated emission. In this theoretical study, we find a resonant TE mode…
Metallic Electro-Optic Effect in Twisted Double-Bilayer Graphene
D. J. P. de Sousa, N. Roldan-Levchenko, C. O. Ascencio +3
Recent theoretical advances have highlighted the role of Bloch state intrinsic properties in enabling unconventional electro-optic (EO) phenomena in bulk metals, offering novel str…
Strain Engineering of Altermagnetic Symmetry in Epitaxial RuO Films
Johnathas D. S. Forte, Seung Gyo Jeong, Anand Santhosh +3
The magnetic ground state of RuO has been under intense debate. Using first-principles calculations, we show that compressive strain along [001] direction stabilizes an alterma…
Boosting quantum yields in 2D semiconductors via proximal metal plates
Yongjun Lee, Anshuman Kumar, Johnathas D'arf Severo Forte +8
Monolayer transition metal dichalcogenides (1L-TMDs) have tremendous potential as atomically thin, direct bandgap semiconductors that can be used as convenient building blocks for…
Dirac spectrum in gated multilayer black phosphorus nanoribbons
J. D. S. Forte, D. J. P. de Sousa, J. Milton Pereira
We investigate the effects of a perpendicular electric field applied to multilayer phosphorene nanoribbons with zigzag and armchair edges. Within the context of the tight-binding m…
