Photovoltaic efficiency of transition metal dichalcogenides thin films by ab initio excited-state methods

Autor: Marinho Jr., Enesio, Villegas, Cesar E. P., Venezuela, Pedro, Rocha, Alexandre R.

Transition metal dichalcogenides (TMDCs) have garnered significant interest in optoelectronics, owing to their scalability and thickness-dependent electrical and optical properties. In particular, thin films of TMDCs could be used in photovoltaic dev

Me-graphane: tailoring the structural and electronic properties of Me-graphene by hydrogenation

Autor: Marinho Jr, Enesio, Autreto, Pedro A. S.

Graphene-based materials (GBMs) constitute a large family of materials which has attracted great interest for potential applications. In this work, we apply first-principles calculations based on density functional theory (DFT) and fully atomistic re
