Phase-Dependent Excitonic Light Harvesting and Photovoltaic Limits in Monolayer Y2TeO2 MOenes
Bill D. A. Huacarpuma, Jose A. dos S. Laranjeira, Nicolas F. Martins +5
We investigate phase-dependent electronic and excitonic phenomena in monolayer Y2TeO2 MOenes in the 1T and 2H polymorphs using first-principles theory and an effective many-body fr…
Goldene monolayer as a highly effective catalyst for polysulfide anchoring and conversion: A theoretical study
Nicolas F. Martins, José A. dos S. Laranjeira, Bill D. A. Huacarpuma +3
We use first-principles density functional theory to investigate how lithium sulfide and polysulfide clusters (Li2S, Li2S2, Li2S4, Li2S6, Li2S8, and S8) bind to Goldene, a new two-…
Exploring the Potential of Two-dimensional Borospherene for Toxic Gas Sensing and Capture: A DFT Study
Nicolas F. Martins, José A. dos S. Laranjeira, Kleuton A. L. Lima +2
Two-dimensional (2D) boron-based materials have gained increasing interest due to their exceptional physicochemical properties and potential technological applications. In this way…
A Three-Dimensional Dodecaphenylyne-Derived Carbon Allotrope with Anisotropic and Auxetic-Like Mechanical Behavior
Kleuton A. L. Lima, José A. dos S. Laranjeira, Bill D. A. Huacarpuma +4
We introduce 3D-DPhyne, a novel three-dimensional (3D) carbon allotrope derived from the dodecaphenylyne framework, and investigate its structural, electronic, optical, and mechani…
Quadrene: A Novel Quasi-2D Carbon Allotrope with High Carrier Mobility
Kleuton A. L. Lima, José A. dos S. Laranjeira, Neymar J. N. Cavalcante +4
We present a comprehensive first-principles investigation of a novel carbon allotrope characterized by quasi-tetragonal atomic motifs and quasi-two-dimensional structural behavior.…
Sodium-Decorated Ennea-Graphene: A Novel 2D Carbon Allotrope for High-Capacity Hydrogen Storage
Bill D. Aparicio Huacarpuma, José A. S. Laranjeira, Nicolas F. Martins +4
The development of safe, efficient, and reversible hydrogen storage materials is critical for advancing hydrogen-based energy technologies and achieving carbon-neutral goals. Ennea…
