Charge carrier dynamics and optoelectronic properties in quantum tunneling heterostructures
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus 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 ...
Effect of Aging on the Electrochemical Performance of LSM-YSZ Cathodes
(Electrochemical Society, 2015-06-12)
Investigations of degradation mechanisms of solid oxide fuel cells are crucial for achieving a widespread commercialization of the technology. In this work, electrochemical impedance spectroscopy (EIS) was applied for ...
Nanomagnet coupled to quantum spin Hall edge: An adiabatic quantum motor
(Elsevier Science, 2015-11)
The precessing magnetization of a magnetic islands coupled to a quantum spin Hall edge pumps charge along the edge. Conversely, a bias voltage applied to the edge makes the magnetization precess. We point out that this ...
On the Mechanism of the Iodide–Triiodide Exchange Reaction in a Solid-State Ionic Liquid
(American Chemical Society, 2017-06)
Efficient charge transport has been observed in iodide-based room-temperature ionic liquids when doped with iodine. To investigate preferred pathways for the iodide (I-)-to-triiodide (I3 -) exchange reaction and to clarify ...

Nicosulfuron sorption kinetics and sorption/desorption on volcanic ash-derived soils: poposal of sorption and transport mechanisms
(Elsevier, 2020)
Nicosulfuron sorption/desorption kinetics were studied through batch sorption studies in ten volcanic ash-derived Andisol and Ultisol soils with acidic pH and variable surface charge. Two different kinetic models were used ...
