A Concise Review of Recently Synthesized 2D Carbon Allotropes: Amorphous Carbon, Graphynes, Biphenylene and Fullerene Networks
Ricardo Paupitz, Alexandre F. Fonseca, Mizraim Bessa +6
Two-dimensional (2D) carbon allotropes have received considerable attention due to their unique properties and potential applications in several fields, including electronics, cata…
Covalent Adsorption of functional groups on [N]-carbophenes
Chad E. Junkermeier, George Psofogiannakis, Ricardo Paupitz
Starting from the planar molecule 1,3,5-trihydroxybenzene, Du et al. reported synthesizing one of a couple of possible 2D materials: graphenylene or 3-carbophene. 3-carbophene is a…
Auxetic properties of a newly proposed -graphyne-like material
Ricardo Paupitz, Tales J. da Silva, Marilia J. Caldas +2
In this work, we propose a new auxetic (negative Poisson's ratio values) structure, based on a -graphyne structure, here named . Graphynes are 2D carbon allotro…
N-Carbophenes: two-dimensional covalent organic frameworks derived from linear N-phenylenes
Chad E. Junkermeier, Jay Paul Luben, Ricardo Paupitz
N-Carbophene (carbophene) is a novel class of two-dimensional covalent organic frameworks (2DCOF), based on linear N-phenylenes, that have moderate band gaps and low-mobility bands…
Ground state determination and band gaps of bilayers of graphenylenes and octafunctionalized-biphenylenes
Chad E. Junkermeier, Ricardo Paupitz
Device fabrication often requires materials that are either reliably conducting, reliably semiconducting, or reliably nonconducting. Bilayer graphene (BLG) changes from a supercond…
Specific Heat Anomalies in Solids Described by a Multilevel Model
Mariano de Souza, Ricardo Paupitz, Antonio Seridonio +1
Specific heat measurements constitute one of the most powerful experimental methods to probe fundamental excitations in solids. After the proposition of Einstein's model, more than…
Inorganic Graphenylene: A Porous Two-Dimensional Material With Tunable Band Gap
Eric Perim, Ricardo Paupitz, Pedro Alves da Silva Atreto +1
By means of ab initio calculations we investigate the possibility of existence of a boron nitride (BN) porous two-dimensional nanosheet which is geometrically similar to the carbon…
