One Step Fabrication of Low Noise CuO Nanowire-Bridge Gas Sensor
International Journal of Electrochemical Science, 2013 We report a new method to fabricate the CuO nanowire-bridge device operating one step thermal treatment and implementing as gas sensor. The X-ray Diffraction (XRD), micro Raman, and high resolution transmission electron microscopy measurements indicated ...

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells
Advanced Materials, EarlyView.Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

AIP Advances, 2013 We investigated the growth, structure, and electrical properties of InAs nanowires grown in the Au-free vapor-liquid-solid mode. We demonstrated the self-assisted vapor-liquid-solid growth of InAs nanowire with self-assembled In particles on InP ...

Advanced Materials, EarlyView.Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).

New Journal of Physics, 2015 We investigate the polarization of excitonic transitions of single dispersed GaN nanowires with a diameter of about 50 nm. We observe donor-bound exciton transitions with a linewidth narrower than 250 μ eV at 10 K, whereas the luminescence from free ...

Modeling Nanowire Indentation Test With Adhesion Effect
, 2011 Because of the large aspect ratio of its length to radius and the large surface area to volume ratio, the nanowire is highly flexural and susceptible to the adhesion influence.

AC-assisted single-nanowire electromechanical switch [PDF]
, 2018 A unique two-source controlled nanoelectromechanical switch has been assembled from individual, single-clamped Ge nanowires. The switching behaviour was achieved by superimposing the control signals of specific frequencies to the electrostatic potential ...

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond
Advanced Materials, EarlyView.Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Nanoscale heat generation in a single Si nanowire
NanophotonicsWe develop a nanoheater utilizing a single Si nanowire with a porous segment that produces localized heat. The 19-fold higher resistivity of the porous segment compared to the solid segment in the nanowire facilitates the substantial confinement of heat ...
