Suppression of non-radiative surface recombination by N incorporation in GaAs/GaNAs core/shell nanowires

Suppression of non-radiative surface recombination by N incorporation in GaAs/GaNAs core/shell nanowires

III-V semiconductor nanowires (NWs) such as GaAs NWs form an interesting artificial materials system promising for applications in advanced optoelectronic and photonic devices, thanks to the advantages offered by the 1D architecture and the possibility to combine it with the main-stream silicon technology. Alloying of GaAs with nitrogen can further enhance performance and extend device function...

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

Dramatic reduction of surface recombination by in situ surface passivation of silicon nanowires.

Nanowires have unique optical properties and are considered as important building blocks for energy harvesting applications such as solar cells. However, due to their large surface-to-volume ratios, the recombination of charge carriers through surface states reduces the carrier diffusion lengths in nanowires a few orders of magnitude, often resulting in the low efficiency (a few percent or less...

Origin of radiative recombination and manifestations of localization effects in GaAs/GaNAs core/shell nanowires

Separation and Recovery of Platinum by Magnetic Coreshell Nanostructures Modified with N-(2-aminoethyl)-3- aminopropyltrimethoxysilane

In this paper, Fe3 O4 @SiO2 core/shell magnetic nanostructure has been synthesized and modified by N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS). Fe3 O4 @SiO2 was used as a novel adsorbent for separation of hexachloroplatinic acid. X-ray diffraction (XRD), scanning electron microscopy (SEM), and FT-IR technique were used to characterize morphologies and surface texturing of these ads...
