Unusual effects of nanowire-nanowire junctions on the persistent photoconductivity in SnO2 nanowire network devices
(2021-01-01)
The persistent photoconductivity (PPC) effect is a commonly observed behavior in SnO2 nanostructures. Here we described and studied this effect through a comparative study, based on measurements of electronic transport ...
Transient decay of photoinduced current in semiconductors and heterostructures
(2020-01-01)
Defects that exhibit some sort of lattice relaxation usually present an energy barrier for electron capture, and the possibility of developing the phenomenon known as persistent photoconductivity (PPC). In this effect, ...
Observation of persistent photoconductivity in vanadyl phthalocyanine
(Iop Publishing Ltd, 2008-06-21)
Persistent photoconductivity (PPC) in vanadyl phthalocyanine (VOPc) organic light-emitting diodes was investigated using photoconductive time response, photocurrent-voltage characteristics and charge extraction in linearly ...

Transporte eletrônico em nanofios de SnO2 dopado com Sb: transição metal-isolante induzida pela dopagem e fotocondutividade persistente
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2019-03-15)
In this work we studied the structural, optical and electronic transport properties of intrinsic and doped SnO2 nanowires with different concentrations of antimony (Sb) grown by the Vapor-Liquid-Solid mechanism (VLS). ...

Investigação das propriedades estruturais, ópticas e elétricas de filmes finos de SnO2 dopado com Pb2+ e estudo da heteroestrutura TiO2/PbxSn1-xO2
(Universidade Estadual Paulista (Unesp), 2021-03-18)
Este trabalho consistiu na produção de pós e filmes finos de SnO2 dopado com Pb2+, depositados através da técnica sol-gel-dip-coating. Para os pós, a caracterização se limitou a análise morfológica e composicional, porém, ...
