On the Mechanical, Electronic, and Optical Properties of 8-16-4 Graphyne: A 2D Carbon Allotrope with Dirac Cones
Raphael M. Tromer, Marcelo L. Pereira Junior, Kleuton A. L. Lima +4
Due to the success achieved by graphene, several 2D carbon-based allotropes were theoretically predicted and experimentally synthesized. We used density functional theory and react…
Transforming 2D carbon allotropes into 3D ones through topological mapping: The case of biphenylene carbon (graphenylene)
Raphael M. Tromer, Levi C. Felix, Ray H. Baughmann +2
In this work, we propose a new methodology for obtaining 3D carbon allotrope structures from 2D ones through topological mapping. The idea is to select a 3D target structure and 's…
The Effect of Element Composition on the Structural and Electronic Properties of Carbon, Silicon, Silicon Carbide, and Boron Nitride Gyroid Schwarzites
Raphael M. Tromer, Levi C. Felix, Cristiano F. Woellner +1
Schwarzites are porous structures that present negative Gaussian curvatures. Although initially proposed for carbon, in principle, schwarzites of other elements are possible. In th…
Two-dimensional (2D) d-Silicates from abundant natural minerals
Preeti Lata Mahapatra, Appu Kumar Singh, Raphael Tromer +8
In the last decade, the materials community has been exploring new 2D materials (graphene, metallene, TMDs, TMCs, MXene, among others) that have unique physical and chemical proper…
