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 ...
Correlation between structure and optical properties of lead metasilicate glass-ceramic under high hydrostatic pressures
(Universidade Federal de São Carlos, 2022-09-21)
Glass structures are determined by not only composition, pressure, and temperature but also by the pressure and thermal histories in which the glass was submitted. In this thesis, a systematic study of these variables was ...
Theoretical and experimental investigation on the visible-light controlled functional properties in charged domain wall ferroelectrics
(Universidade Federal de São Carlos, 2023-04-13)
Optical control of ferroelectric properties have been attracted a growing interest as an
alternative to the conventional control by applied electric fields. However, the major
drawback for achieving an effective reversible ...
