• Structural properties of nanoscopic ring systems and their optical response 

      Oliveira Neto, Vivaldo Lopes (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 30/03/2016)
      In this thesis, the electronic and structural properties of nanostructured systems were studied aiming to get a realistic model for quantum rings, potentially adaptable for quantum dots. To attain these goals, several ...
    • Propriedades de sistemas de pontos quânticos semicondutores acoplados e sua resposta óptica 

      Cabral, Luís Antônio (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 31/10/2017)
      The study of doped semiconductor quantum dots with magnetic impurities has been a challenging task when adding spin-orbit coupling and exchange interaction with asymmetry effects. The combination of all these factors within ...
    • The memristive response in solids 

      Silva, Rafael Schio Wengenroth (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 07/08/2023)
      In this Master Thesis, we have investigated basic ingredients of the theory of solid state transport, namely the Drude like conductivity and the activation of nonequilibrium charge carriers subjected to a relaxation time, ...
