Caracterização das propriedades ópticas e de spin de poços quânticos de InGaAsN/GaAs
(Universidade Federal de São Carlos, 2015-03-30)
In this work, it was investigated the optical and magneto-optical properties of In- GaAsN/GaAs and InGaAs/GaAs double quantum wells. It was performed a systematic experimental study of photoluminescence (PL) as a function ...
Propriedades eletrônicas de nanofios semicondutores de Fosfeto de Zinco (Zn3P2)
(Universidade Federal de São Carlos, 2018-04-20)
Zinc phosphide Zn3P2 nanowires with excellent crystalline quality were grown using the Vapor-Liquid-Solid (VLS) method with gold nanoparticles as catalysts. Single nanowire based devices were fabricated with ohmic nickel ...
