Tunable Interlayer Excitons in Bilayer Graphene Nanoribbons
Alexandre R. Rocha, Rodrigo G. Amorim, Wanderlã L. Scopel +1
Vertically stacked van der Waals structures are promising platforms that enable layer engineering, opening new avenues for the quantum control of elementary excitations, including…
Determining Exciton Binding Energy and Reduced Effective Mass in Metal Tri-Halide Perovskites from Optical and Impedance Spectroscopy Measurements
K. Lizárraga, J. A. Guerra, L. A. Enrique-Moran +5
Accurate determination of the exciton binding energy and reduced effective mass in halide perovskites is of utmost importance for the selective design of optoelectronic devices. Al…
Suppression of the Mott insulating phase in the particle-hole asymmetric Hubbard model
Mateus Marques, Bruno M. de Souza Melo, Alexandre R. Rocha +2
We explore the phase diagram of the Mott metal-insulator transition (MIT), focusing on the effects of particle-hole asymmetry (PHA) in the single-band Hubbard model. Our dynamical…
Optical properties of TiS as a novel thin film for single-junction and tandem solar cells
Cesar E. P. Villegas, Enesio Marinho, A. C. Dias +2
Sub-micrometer thin films are promising platforms for emerging flexible photovoltaic devices. Although the current market already produces efficient solar cells, the average wafer…
Probing Water-Electrified Electrode interfaces: Insights from Au and Pd
Graciele M. Arvelos, Marivi Fernández-Serra, Alexandre R. Rocha +1
The water/electrode interface under an applied bias potential is a challenging out-of-equilibrium phenomenon, which is difficult to accurately model at the atomic scale. In this st…
