Processamento convencional e assistido por campo elétrico (Flash Sintering) de cerâmicas livres de chumbo baseadas em K0,5Na0,5NbO3: propriedades físicas finais
(Universidade Federal de São Carlos, 2020-08-07)
K0,5Na0,5NbO3 (KNN)-based ceramics are considered promising candidates to replace lead-based piezoelectric ceramics, such as Pb(ZrxTi1−x)O3, which are widely used in electro electronic devices. However, obtaining KNN-based ...
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 ...
The memristive response in solids
(Universidade Federal de São Carlos, 2023-08-07)
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, ...
