We investigate the transport properties of silicon nanowires coated with zinc sulfide nanoparticles. Silicon nanowires were prepared by metal assisted electro-less chemical etching technique. The diameter of nanowires varies from 30 to 300 nm and length was 30 mm. Zinc sulfide nanoparticles having diameter 30 nm were synthesized by co-precipitation method. The nanoparticles were then deposited ...

This paper shows that nickel nanowires of length 11μm and diameters 800 and 15nm were grown within the pores of nuclear track polycarbonate membrane by electrodepositing nickel. Surface morphology and crystallographic structure of the deposited nanowires was investigated using SEM, TEM and XRD respectively. It is found that low current density gives good result, while high current density leads...

We report the fabrication of thermoelectric bismuth teUuride nanowires using the template synthesis method. A simple electrodeposition procedure was used to produce the nanowires within the pores of an alumina filtration membrane. The resulting bismuth telluride/alumina composite membranes constitute an array of thermoelectric nanowires surrounded by a thermally and electrically insulating matr...

Silver nanowires were synthesized by solvothermal method through reducing silver nitrate (AgNO3) with ethylene glycol (EG) in the presence of polyvinylpyrrolidone (PVP). In order to prevent the agglomeration of Ag+ in the initial Ag seeds formation, sodium chloride (NaCl) was added into the solution to form AgCl colloids. By dissolving AgCl in the late stages, Ag+ ions were released into the so...

In this study, we synthesis one-dimensional (1D) manganese(III) Schiff base coordination polymer [Mn(Brsalophen)(μ1,3-N3)]n by reaction of MnCl2·6H2O and tetradentate Schiff base ligand Brsalophen at the presence of NaN3 in methanol and characterized by elemental analyses (CHN) and FT-IR spectroscopy. It was used as a new precurs...

Ni nanowires are synthesized by template based electrochemical technique. A commercially available filter membrane of alumina anodic oxide (AAO) is used for the fabrication of nanowires. AAO membrane supported on copper substrate yields better hexagonal nanowires. Morphological studies of nanowires are carried out using scanning electron microscopy (SEM). The analysis shows the fabrication of v...

Controlling the post-growth assembly of nanowires is an important challenge in the development of functional bottom-up devices. Although various methods have been developed for the controlled assembly of nanowires, it is still a challenging issue to align selectively heterogeneous nanowires at desired spatial positions on the substrate. Here we report a size selective deposition and sequential ...

It has been widely reported that twin boundaries strengthen nanowires regardless of their morphology-that is, the strength of nanowires goes up as twin spacing goes down. This article shows that twin boundaries do not always strengthen nanowires. Using classical molecular dynamics simulations, the authors show that whether twin boundaries strengthen nanowires depends on the necessary stress for...

A new technique is reported for the transformation of smooth nonpolar ZnO nanowire surfaces to zigzagged high-index polar surfaces using polycrystalline ZnO thin films deposited by atomic layer deposition (ALD). The c-axis-oriented ZnO nanowires with smooth nonpolar surfaces are fabricated using vapor deposition method and subsequently coated by ALD with a ZnO particulate thin film. The synthes...
