Extreme-ultraviolet optical response of atomically-thin molybdenum disulfide
G. Fiorentini, N. Di Palo, G. Inzani +18
We report multi-angle reflectivity measurements in the extreme-ultraviolet (XUV) range for mono- and bilayer MoS on a SiN substrate. Using a single-sheet 2D conductivit…
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…
Excitons in nonlinear optical responses: shift current in MoS and GeS monolayers
J. J. Esteve-Paredes, M. A. García-Blázquez, A. J. Uría-Álvarez +2
It is well-known that exciton effects are determinant to understand the optical absorption spectrum of low-dimensional materials. However, the role of excitons in nonlinear optical…
Shift current with Gaussian basis sets general prescription for maximally-symmetric summations in the irreducible Brillouin zone
M. A. García-Blázquez, J. J. Esteve-Paredes, A. J. Uría +1
The bulk photovoltaic effect is an experimentally verified phenomenon by which a direct charge current is induced within a non-centrosymmetric material by light illumination. Calcu…
Efficient computation of optical excitations in two-dimensional materials with the Xatu code
Alejandro José Uría-Álvarez, Juan José Esteve-Paredes, Manuel Antonio García-Blázquez +1
Here we describe an efficient numerical implementation of the Bethe-Salpeter equation to obtain the excitonic spectrum of semiconductors. This is done on the electronic structure c…
Quenching of exciton recombination in strained two-dimensional monochalcogenides
J. J. Esteve-Paredes, Sahar Pakdel, J. J. Palacios
We predict that long-lived excitons with very large binding energies can also exist in a single or few layers of monochalcogenides such as GaSe. Our theoretical study shows that ex…
