Crystallization at room temperature from amorphous to trigonal selenium as a byproduct of the synthesis of water dispersible zinc selenide
(Elsevier B.V., 2012-11-15)
Zinc selenide is a semiconductor material that has been synthesized in aqueous media. However, this synthesis can yield some byproducts, which has been little exploited in literature of this area; one of these byproducts ...
Planning accelerated life tests under Exponentiated-Weibull-Arrhenius model
(2008-07-08)
Purpose - The purpose of this paper is to present designs for an accelerated life test (ALT). Design/methodology/approach - Bayesian methods and simulation Monte Carlo Markov Chain (MCMC) methods were used. Findings - In ...
Insulator-to-metal transition driven by clustering of solitons in polyacetylene
(1997-03-15)
It's believed that the simple Su-Schrieffer-Heeger Hamiltonian can not predict the insulator to metal transition of transpolyacetylene (t-PA). The soliton lattice configuration at a doping level y=6% still has a semiconductor ...
Binding energies of excitons trapped by ionized donors in semiconductors
(American Physical Soc, 2001-11-15)
Using the hyperspherical adiabatic approach in a coupled-channel calculation, we present precise binding energies of excitons trapped by impurity donors in semiconductors within the effective-mass approximation. Energies ...
Magnetotunneling spectroscopy of a biased triple-barrier semiconductor heterostructure

Morphological modifications and surface amorphization in ZnO sonochemically treated nanoparticles
(2013-05-01)
Application of nanoscale materials in photovoltaic and photocatalysis devices and photosensors are dramatically affected by surface morphology of nanoparticles, which plays a fundamental role in the understanding of the ...
In vitro assessment of pulp chamber temperature of different teeth submitted to dental bleaching associated with LED/laser and halogen lamp appliances
(2008-07-01)
This study sought to assess the pulp chamber temperature in different groups of human teeth that had been bleached using hydrogen peroxide gel activated with halogen lamps or hybrid LED/laser appliances. Four groups of ten ...
Electrical characterization of poly(amide-imide) for application in organic field effect devices
(Elsevier B.V., 2012-10-01)
The admittance spectra and current-voltage (I-V) characteristics are reported of metal-insulator-metal (MIM) and metal-insulator-semiconductor (MIS) capacitors employing cross-linked poly(amide-imide) (c-PAI) as the insulator ...
Deposition and characterization of BiVO4 thin films and evaluation as photoanodes for methylene blue degradation
(Springer, 2012-10-01)
Thin films of bismuth vanadate (BiVO4) are deposited through the solution combustion synthesis technique coupled with the dip-coating process. Thermal gravimetric analyis shows a total mass loss of 71 % besides the formation ...
