The Effect of Rapid Thermal Annealing on InAs/GaAs Quantum Dot Solar Cells

The effect of post-growth annealing on InAs/GaAs quantum dot solar cells (QDSCs) has been studied. A significant improvement in photoemission, photocurrent density, and spectral response has been observed with post-growth annealing. The optimal anneal temperature was found to be 700 ° C, which lead to an 18% improvement in current density from 4.9 mA cm -2 for as-grown sample to 5.8 mA cm -2 . ...

Effect of Post-Deposition Annealing On Hydrogenated Amorphous Silicon Thin Films Grown At High Power by Pecvd

The crystallization of hydrogenated amorphous silicon layers (a-Si:H) [1,2] deposited by plasma enhanced chemical vapor deposition (PECVD) is of great interest. Generally, laser or metals are used to induce crystallization in aSi:H films. We have found that films deposited at high rf power (> 0.2 W/cm2) by PECVD technique shows some crystallites embedded in a-Si:H matrix and their after its vac...

The Effect of Annealing, Synthesis Temperature and Structure on Photoluminescence Properties of Eu-Doped ZnO Nanorods

In this study un-doped and Eu-doped ZnO nanorods and microrads were fabricated by Chemical Vapor Deposition (CVD) method. The effects of annealing, synthesis temperature and structure on structural and photoluminescence properties of Eu-doped ZnO samples were studied in detail. Prepared samples were characterized using X-Ray diffraction (XRD), scanning electron microscopy (SEM), particle size a...

Quantum size effect and catalytic activity of nanosized single-crystalline spherical β-Ga2O3 particles by thermal annealing of liquid metal nanoparticles

We report on the synthesis of nanosized single-crystalline spherical b-Ga2O3 particles (GONP) by thermal annealing of gallium nanoparticles (GaNP), which previously has been prepared under ultrasonication. GONP displayed a spherical morphology and the particle size reflected that of GaNP. The nanoparticles have been confirmed as crystalline b-Ga2O3 by powder X-ray diffraction. The selected area...

Photoinduced dehydrogenation of defects in undoped a-si:H using positron annihilation spectroscopy.

We report changes in variable-energy positron annihilation spectroscopy measurements on undoped hydrogenated amorphous silicon films after light soaking. The change, seen predominantly in the high momentum band of the annihilation radiation, is not reversed by thermal annealing. We suggest, following recent models of the Staebler-Wronski effect, that light exposure induces hydrogen trapped in v...
