The efficiency of micro-light-emitting diodes (?-LEDs) depends enormously on the chip size, and this is connected to sidewall-trap-assisted nonradiative recombination. It known that internal quantum (IQE) aluminum gallium indium phosphide (AlGaInP)-based red ?-LEDs much lower than nitride-based ?-LEDs. To establish major reasons giving rise huge IQE discrepancy, we examined limiting factors in ...

BACKGROUND & OBJECTIVES ZCL is a growing threat in many rural areas of Iran which involves 17 out of 31 provinces. This study was conducted from April to November 2011 for evaluation of the efficacy of phostoxin and zinc phosphide against rodents. METHODS Rodent control operations were carried out using phostoxin and zinc phosphide. To evaluate the effect of rodent control operation on the ma...

The electronic and optical properties of three types aluminum phosphide bilayers are examined using density functional theory. results indicate that they all possess proper direct gaps, which exhibit a rich variety behaviors depending on the strain. band gaps these could be easily tuned in energy range from 0 eV to 1.9 under wide biaxial Additionally, gap transitions between indirect found when...

We present an electrode, based on structurally controlled nanowires, as a first step towards developing a useful nanostructured device for neurophysiological measurements in vivo. The sensing part of the electrode is made of a metal film deposited on top of an array of epitaxially grown gallium phosphide nanowires. We achieved the first functional testing of the nanowire-based electrode by perf...
