Journal ArticleDOI
Unexpected transition from single to double quantum well potential induced by intense laser fields in a semiconductor quantum well
Fabio Mitsuo Lima,M. A. Amato,O. A. C. Nunes,Antonio Luciano de Almeida Fonseca,Bernhard Georg Enders,E. F. da Silva +5 more
TL;DR: In this article, a nonperturbative approach based upon the Kramers-Henneberger translation transformation, followed by Floquet series expansions, yields, for sufficiently high frequencies, the so-called "laser-dressed" potential, which is taken for composing a time-independent Schrodinger equation whose solutions are the desired quasistationary states.
Journal ArticleDOI
Electronic properties of a quasi-two-dimensional electron gas in semiconductor quantum wells under intense laser fields
Bernhard Georg Enders,Fabio Mitsuo Lima,O. A. C. Nunes,Antonio Luciano de Almeida Fonseca,D. A. Agrello,Fanyao Qu,E. F. da Silva,Valder N. Freire +7 more
TL;DR: In this paper, the influence of two intense, longwavelength, nonresonant laser fields on the electron energy levels and density of states (DOS) in quantum wells is performed within a Green's function approach.
Journal ArticleDOI
Stability conditions of armchair graphene nanoribbon bipolarons.
Ana Virgínia Passos Abreu,Luiz Antonio Ribeiro Junior,Gesiel Gomes Silva,Marcelo Lopes Pereira Junior,Bernhard Georg Enders,Antonio Luciano de Almeida Fonseca,Geraldo Magela e Silva +6 more
TL;DR: A two-dimensional version of the Su–Schrieffer–Heeger model is used to investigate the stability of bipolarons in armchair graphene nanoribbons (AGNRs) and shows how bipolaron stability is dependent on the strength of the electron–phonon interactions.
Journal ArticleDOI
Adsorption of carbon dioxide and ammonia in transition metal-doped boron nitride nanotubes.
Kleuton Antunes Lopes Lima,Wiliam Ferreira da Cunha,Fábio Ferreira Monteiro,Bernhard Georg Enders,Marcelo Lopes Pereira,Luiz Antonio Ribeiro +5 more
TL;DR: Density functional theory calculations were carried out to analyze the performance of single-walled boron nitride nanotubes (BNNT) doped with Ni, Pd, and Pt as a sensor of CO2 and NH3, suggesting a considerable rise in the adsorption potential of BNNTs when the doping scheme is employed, as compared with Adsorption in pristine nanot tubes.
Journal ArticleDOI
Polaron properties in pentathienoacene crystals
Marcelo Lopes Pereira Junior,Rayane Tayná da Costa Torres,Bernhard Georg Enders,Wiliam Ferreira da Cunha,Rafael Timóteo de Sousa Júnior,Luiz Antonio Ribeiro Junior +5 more
TL;DR: In this article, a two-dimensional tight-binding model is used to study static and dynamical properties of polarons in pentathienoacene crystals, and it is shown that the polaron dynamics can occur for an electric field threshold that overcomes the standard value of organic crystalline semiconductors.
