Surface passivation of (100) GaSb using self-assembled monolayers of long-chain octadecanethiol

AIP Advances, 2016
The passivation of (100) GaSb surface was investigated by means of the long-chain octadecanethiol (ODT) self-assembled monolayer (SAM). The properties of ODT SAM on (100) GaSb were characterized by the atomic force microscopy using Kelvin probe force ...

Bio‐Inspired Hierarchical Nanoreactor With Hetero‐Coordinated Fe–P–Co Bridges for Whole‐Pathway‐Regulated Electrocatalytic Oxygen Reduction

Advanced Materials, EarlyView.
A bioinspired Co‐doped Fe2P on N‐doped carbon with a hierarchical eucalyptus‐like nanoarchitecture is engineered to regulate oxygen across the entire electrochemical pathway, achieving a half‐wave potential of 0.938 V vs. RHE, sustaining 373 h of discharge in Al‐air batteries, and delivering an energy density of 3487 Wh/kg.

Vickers Hardness of Diamond and cBN Single Crystals: AFM Approach

Crystals, 2017
Atomic force microscopy in different operation modes (topography, derivative topography, and phase contrast) was used to obtain 3D images of Vickers indents on the surface of diamond and cBN single crystals with high spatial resolution.

Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

Advanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

Combined scanning probe electronic and thermal characterization of an indium arsenide nanowire

Beilstein Journal of Nanotechnology, 2018
As electronic devices are downsized, physical processes at the interface to electrodes may dominate and limit device performance. A crucial step towards device optimization is being able to separate such contact effects from intrinsic device properties ...

Polarized Tips or Surfaces: Consequences in Kelvin Probe Force Microscopy

e-Journal of Surface Science and Nanotechnology, 2011
In this work, we present non-contact atomic force microscopy (nc-AFM) and Kelvin probe force microscopy (KPFM) simulations of the (001) surface of silver and supported MgO thin films. From the calculated force spectroscopy, we predict atomic resolution at tip-surface distances of less than 5 A.

Site‐Selective Polyvinylpyrrolidone Adsorption Behavior for 3D Heterogeneous Integration

Advanced Materials Technologies, EarlyView.
Site‐selective adsorption behavior is presented with polyvinylpyrrolidone on a Cu/SiO2 pattern wafer, which enables 3D heterogeneous integration. Owing to the site‐selective adsorption behavior and its corresponding electrostatic interaction between SiO2 nanoparticles and the Cu surface, the selectivity of Cu/SiO2 is arbitrarily controlled ...
