Local work function analysis of Pt/TiO_2 photocatalyst by a Kelvin probe force microscope

Local work function analysis of Pt/TiO_2 photocatalyst by a Kelvin probe force microscope
Nanometre-sized Pt clusters were prepared on a TiO_2(110)-(1 × 1) surface, and the lateral distribution of work function was examined by using a Kelvin probe force microscope. Local work function on the Pt clusters was smaller than that on the surrounding TiO_2 surface. Assuming that the dipole moments which perturb work function are produced by uneven

Opportunities for 2D‐Material‐Based Multifunctional Devices and Systems in Bioinspired Neural Networks

Small, EarlyView.
Bio‐inspired computing offers a route to highly energy‐efficient artificial intelligence. The unique physical properties of two‐dimensional (2D) materials can further enhance such computing approaches. This perspective highlights recent developments in 2D materials‐based neuromorphic devices and discusses future opportunities for integrating such novel

Impact of Structural Heterogeneities in Hierarchically Grown Microribbons on 2D WS2 Monolayer on the Measured Local Hydrogen Evolution Activity on Au Substrate

Small, EarlyView.
Spatially resolved SECCM measurements reveal that hierarchically grown microribbons on 2D WS2 drastically suppress local HER activity. Relative to the basal plane of the 2D monolayer directly supported on an Au substrate, single‐layer and multilayer microribbons exhibit more than a ∼5‐fold and >10‐fold decrease in current density, respectively.

In Situ Growth of 2D Perovskite Nanocrystals to Induce β–Phase of PVDF for Piezoelectric Nanogenerators with Ultra‐High Output Voltage

Small, EarlyView.
In situ grown 2D perovskite nanocrystals embedded in PVDF enable flexible piezoelectric nanogenerators with greatly enhanced β‐phase content and a high d33∗${\mathrm{d}}_{33}^{\mathrm{*}}$ of 35.16 pm/V. The devices deliver up to 66.54 V, exhibit light‐enhanced piezoelectricity, and maintain durability over 12000 cycles, offering a stable energy source

Strained 2D Semiconductor Lateral Heterojunctions via Grayscale Thermal‐Scanning Probe Lithography

Small Science, EarlyView.
A novel strain‐engineering approach using grayscale thermal‐Scanning Probe Lithography tailors the optoelectronic response of 2D Transition‐Metal Dichalcogenide (TMD) layers. Nanofaceted templates control local strain in MoS2, enabling engineered carrier extraction in asymmetric Au‐MoS2 lateral heterojunction nanoarrays, as detected by Kelvin Probe ...
