Polaritons de exciton em super-redes semicondutoras
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2004-12-03)
In this work we study the spectrum (bulk and surface modes) of exciton-polaritons in infinite and semi-infinite binary superlattices (such as, ···ABABA···), where the semiconductor medium (A), whose dielectric function ...
Dark exciton preparation in a quantum dot by a longitudinal light field tuned to higher exciton states
(American Physical Society, 2021-01)
Several important proposals to use semiconductor quantum dots in quantum information technology rely on the control of the dark exciton ground states, such as dark exciton based qubits with a microsecond lifetime. In this ...
Excitons in undoped AlGaAs/GaAs wide parabolic quantum wells
(2010-04-12)
In this work the electronic structure of undoped AlGaAs/GaAs wide parabolic quantum wells (PQWs) with different well widths (1000 and 3000 ) were investigated by means of photoluminescence (PL) measurements. Due to the ...
