High Resolution Parameter Space from a Two Level Model on Semi-Insulating GaAs
S. L. da Silva, E. R. Viana, A. G. de Oliveira +2
Semi-insulating Gallium Arsenide (SI-GaAs) samples experimentally show, under high electric fields and even at room temperature, negative differential conductivity in N-shaped form…
Photoluminescence and High Temperature Persistent Photoconductivity Experiments in SnO2 Nanobelts
E. R. Viana, J. C. González, G. M. Ribeiro +1
The Persistent Photoconductivity (PPC) effect was studied in individual tin oxide (SnO2) nanobelts as a function of temperature, in air, helium, and vacuum atmospheres, and low tem…
3D Hopping Conduction in SnO2 nanobelts
E. R. Viana, J. C. Gonzalez, G. M. Ribeiro +1
The temperature dependence of the electrical transport of a individual tin oxide nanobelt was measured, in darkness, from 400 to 5K. We found four intrinsic electrical transport me…
Quantized conductance in SnO2 nanobelts with rectangular hard-walls
E. R. Viana, J. C. Gonzalez, G. M. Ribeiro +1
Quantized conductance is reported in high-crystalline tin oxide (SnO2) nanobelt back-gate field-effect transistors, at low temperatures. The quantized conductance was observed as c…
