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, ...

Influence of Pb2+ doping in the optical and electro-optical properties of SnO2 thin films
(2022-02-15)
Different types of doping incorporated to tin dioxide (SnO2) have been reported in order to control its bandgap aiming optoelectronic applications, such as transparent electrodes, solar cells and displays. In this work, ...
Investigation of temperature influence on photo-induced conductivity in n-type AlxGa1-xAs
(1998-12-01)
We present conductance as function of temperature (G×T) under influence of monochromatic light in the range 0.5-1.5 μm for direct as well as indirect bandgap n-type AlxGa1-xAs. Results obtained below 60 K in indirect bandgap ...
