Graphitic platform for self-catalysed InAs nanowires growth by molecular beam epitaxy [PDF]

, 2014
We report the self-catalysed growth of InAs nanowires (NWs) on graphite thin films using molecular beam epitaxy via a droplet-assisted technique. Through optimising metal droplets, we obtained vertically aligned InAs NWs with highly uniform diameter ...

Nanowire Lasers

Nanophotonics, 2014
Abstract: We review principles and trends in the use of semiconductor nanowires as gain media for stimulated emission and lasing. Semiconductor nanowires have recently been widely studied for use in integrated optoelectronic devices, such as light‐emitting diodes (LEDs), solar cells, and transistors.

Surface functionalization of III-V Nanowires

, 2021
The physical and chemical properties of semiconductor nanowires are significantly influenced by their surface structure and morphology. This can be understood in that surfaces make out a much larger part of the total structure as compared to macroscale ...

Synthesis and Magnetic Properties of NiCo Nanowire Array by Potentiostatic Electrodeposition

International Journal of Electrochemical Science, 2014
NiCo alloy nanowires have been fabricated by electrodeposition using anodized aluminum oxide templates. Growth of nanowires consists of four different stages namely nucleation, steady state growth, filling of pores, and coverage of filled nanowires on ...

Do Twin Boundaries Always Strengthen Metal Nanowires?

Nanoscale Research Letters, 2008
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.

Mechanism of vertical Ge nanowire nucleation on Si (111) during subeutectic annealing and growth [PDF]

, 2011
The direct integration of Ge nanowires with silicon is of interest in multiple applications. In this work, we describe the growth of high-quality, vertically oriented Ge nanowires on Si (111) substrates utilizing a completely sub-Au-Si-eutectic annealing

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

Advanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

Achieving thermally conductive low loss PVDF-based dielectric composites via surface functionalization and orientation of SiC nanowires

eXPRESS Polymer Letters, 2020
Semi-conductive silicon carbide (SiC) nanowires were amino-functionalized to achieve better dispersion in poly(vinylidene fluoride) (PVDF) matrix. It was found that PVDF based composites with amino-functionalized SiC (f-SiC) nanowires exhibited lower ...
