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 ...
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 ...
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 ...
