A DFT Investigation of the Electronic and Optical Properties of Pentadiamond
Raphael M. Tromer, Levy C. Felix, Cristiano F. Woellner +1
Recently, a new carbon 3D carbon allotrope named pentadiamond was proposed. Pentadiamond is composed of carbon atoms in mixed sp and sp-like hybridization. In this work, we…
Optoelectronic Properties of Amorphous Carbon-Based Nanotube and Nanoscroll
Raphael M. Tromer, Levi C. Felix, Luiz A. Ribeiro +1
Free-standing monolayer amorphous carbon (MAC) is a pure carbon structure composed of randomly distributed atom rings with different sizes, which was recently synthesized. In this…
Thiophene-Tetrathia-Annulene monolayer (TTA-2D): A new 2D semiconductor material with indirect bandgap
Raphael M. Tromer, Leonardo D. Machado, Cristiano F. Woellner +1
We propose a new 2D semiconductor material (TTA-2D) based on the molecular structure of Thiophene-Tetrathia-Annulene (TTA). The TTA-2D structural, electronic, and optical propertie…
On the Structural Stability and Optical Properties of Germanium-based Schwarzites: A Density Functional Theory Investigation
Raphael M. Tromer, Levi C. Felix, Cristiano F. Woellner +1
Since graphene was synthesized the interest for building new 2D and 3D structures based on the carbon allotropes has been growing every day. One of these 3D structures is know as c…
On the Mechanical and Thermal Stability of Free-standing Monolayer Amorphous Carbon
Levi C. Felix, Raphael M. Tromer, Luiz A. Ribeiro Junior +1
Recently (C.-T. Toh et al., Nature 577, 199 (2020)), the first synthesis of free-standing monolayer amorphous carbon (MAC) was achieved. MAC is a pure carbon structure composed of…
