Controle da emissão visível de nanopartículas baseadas em óxido de zinco
(Universidade Federal de São Carlos, 2021-02-25)
We present a study of the synthesis processes and of the structural, vibrational and optical properties of Zn1-xCdxO nanostructured system. The Zn1-xCdxO samples were synthesized using mechanosynthesis method, in the ...
Estudo do modelo de Hubbard bidimensional não homogêneo via teoria do funcional da densidade
(Universidade Federal de São Carlos, 2021-07-14)
We implemented the DFT calculation through the Kohn-Sham formalism adapted by the methodology μ-BALDA for the inhomogeneous two-dimensional Hubbard model, which is also implemented experimentally on an ultra-cold atom traps ...
Charge carrier dynamics and optoelectronic properties in quantum tunneling heterostructures
(Universidade Federal de São Carlos, 2021-09-17)
Semiconductor quantum tunneling heterostructures offer a wide range of applications as photosensors, lasers, and circuit elements. However, fundamental questions related to energy transfer mechanisms and the correlation ...
Carrier dynamics of low-dimensional semiconductors: from quantum wells and quantum dots to resonant tunneling devices
(Universidade Federal de São Carlos, 2021-07-22)
This thesis aims to study heterostructures and devices that play a fundamental role in modern nanoelectronic technologies, focusing on group III-V semiconductor materials, especially arsenide-based systems, for photodetection ...
