Organic Electronics from Nature: Investigation of the Electronic and Optical Properties of the Isomers of Bixin and Norbixin Present in the Achiote Seeds

Autor: Luiz Antonio Ribeiro Junior, Josiel Silva Crispim, Demetrio A. da Silva Filho, Rafael T. de Sousa Júnior, Igo Torres Lima, Olimpio Pereira de Sá Neto

Organic semiconductors have been widely employed in developing new green energy solutions with good cost-efficiency compromise, such as Organic Photovoltaics (OPVs). The light-harvesting process in OPVs is a crucial aspect, which still needs improvem

A DFT study on the electronic structure of in-plane heterojunctions of graphene and hexagonal boron nitride nanoribbons

Autor: Ramiro M. dos Santos, Rafael T. de Sousa Júnior, Luiz Antonio Ribeiro Junior, William F. Giozza, Renato Batista Santos, Demetrio A. da Silva Filho

Publikováno v: Electronic Structure. 3:024005

The structural similarity between hexagonal boron nitride (h-BN) and graphene nanoribbons allows for the formation of heterojunctions with small chain stress. The combination of the insulation nature of the former and the quasi-metallic property of t

Electronic and structural properties of Janus MoSSe/MoX2 (X = S,Se) in-plane heterojunctions: A DFT study

Autor: Luiz Antonio Ribeiro Junior, Ramiro M. dos Santos, William F. Giozza, Luiz F. Roncaratti, Wiliam Ferreira da Cunha, Rafael T. de Sousa Júnior

Publikováno v: Chemical Physics Letters. 771:138495

The electronic and structural properties of Janus MoSSe/MoX$_2$ (X=S,Se) in-plane heterojunctions, endowed with single-atom vacancies, were studied using density functional theory calculations. The stability of these structures was verified from cohe

On the electronic structure of a recently synthesized graphene-like BCN monolayer from bis-BN cyclohexane with single-atom vacancies: a DFT study

Autor: Rafael T. de Sousa Júnior, William F. Giozza, Luiz Antonio Ribeiro Junior, Demetrio A. da Silva Filho, Ramiro M. dos Santos

Publikováno v: Electronic Structure. 3:014006

Since the rising of graphene, boron nitride monolayers have been deeply studied due to their structural similarity with the former. A hexagonal graphene-like boron–carbon–nitrogen (h-BCN) monolayer was synthesized recently using bis-BN cyclohexan
