Surface lone-pair polarization probed by quantum-geometric transport in tellurium
Nathanael N. Batista, Wendel S. Paz, Manuel Suárez-Rodríguez +10
Stereochemically active lone pairs are ubiquitous microscopic sources of polarity in molecules and solids, but their collective behavior in crystals is often hidden by symmetry or…
Angular-resolved nonlinear optical response as a probe of Lorentz violation in noncentrosymmetric materials
Guilherme J. Inacio, Nathanael N. Batista, Wesley Spalenza +3
We propose a methodology to detect weak Lorentz-violating (LV) backgrounds through the nonlinear shift photocurrent in noncentrosymmetric crystals. Using a spinful Rice--Mele model…
Enabling the bulk photovoltaic effect in centrosymmetric materials through an external electric field
Guilherme J. Inacio, Juan José Esteve-Paredes, Maurício F. C. Martins Quintela +2
We develop a practical approach to electrically tuning the nonlinear photoresponse of two-dimensional semiconductors by explicitly incorporating a static out-of-plane electric fiel…
High current density electrical breakdown of TiS3 nanoribbon-based field-effect transistors
Aday J. Molina-Mendoza, Joshua O. Island, Wendel S. Paz +11
The high field transport characteristics of nanostructured transistors based on layered materials are not only important from a device physics perspective but also for possible app…
Franckeite: a naturally occurring van der Waals heterostructure
Aday J. Molina-Mendoza, Emerson Giovanelli, Wendel S. Paz +11
The fabrication of van der Waals heterostructures, artificial materials assembled by individually stacking atomically thin (2D) materials, is one of the most promising directions i…
Interaction between single vacancies in graphene sheet: An ab initio calculation
Wanderla L. Scopel, Wendel S. Paz, Jair C. C. Freitas
In order to investigate the interaction between single vacancies in a graphene sheet, we have used spin-polarized density functional theory (DFT). Two distinct configurations were…
On the connection between structural distortion and magnetism in graphene with a single vacancy
Wendel S. Paz, Wanderlã L. Scopel, Jair C. C. Freitas
The correlation between structural distortion and emergence of magnetism in graphene containing a single vacancy was investigated using first-principles calculations based on densi…
