Characteristics of nanostructure silicon photodiode using laser assisted etching
(Elsevier B.V., 2013)
We prepared nanostructures silicon photodiode (nPSi) by using laser assisted etching at fixed current density (30 mA/cm2) with different etching wavelengths of laser diode (532, 650 and 810 nm), a (metal/nanostructure ...
Influence of current density on porous silicon characteristics
(Trans Tech Publications, 2013)
Porous silicon structures have been fabricated by electrochemical etching using different current density. From field emission scanning electron microscope images (FE-SEM) it was observed that more uniform distribution of ...
Alternative-current electrochemical etching of uniform porous silicon for photodetector applications
(Electrochemical Science Group, 2013)
The twining of alternative-current (AC) with electrochemical etching (ECE) to fabricate porous silicon (PS) is studied. The porosity percentage is obtained by gravimetric analysis. The effect of different current densities; ...
Structural and morphological studies of cadmium sulfide nanostructures
(Trans Tech Publications, 2013)
Cadmium sulfide (CdS) nanostructures were prepared with different spin coating speed 1000 and 3000 rpm and molarities of Cd:S to be 1.2 to 0.01 mol/L using sol-gel spin coating technique. It is found that the average grain ...
A Novel AC technique for high quality porous GaN
(Electrochemical Science Group (ESG), 2013-04)
In this paper, we report the formation of porous GaN films under a novel alternatingcurrent (sine-wave a.c. (50 Hz)) photo-assisted electrochemical etching (ACPEC) conditions. The ac formed porous GaN with excellent ...
Structural, analysis and optical studies of cadmium sulfide nanostructured
(Elsevier Ltd., 2013)
Cadmium sulfide (CdS) thin films of nanostructure were prepared and deposited on glass substrates with Cd:S (1.2 to 0.05 mol/L) annealed at 400ºC and different spin coating speed (1000 and 5000 rpm) using sol-gel spin ...
Structural and optical properties of PbI2 nanostructures obtained using the thermal evaporation method
(NRC Research Press, 2013-10)
Lead iodide (PbI2) nanostructures were successfully prepared using the thermal evaporation method on a glass substrate at room temperature. The structural properties were analyzed using X-ray diffraction, which revealed ...
