Metal‐Enhanced Charge Transport and its Mechanism in Atomically Precise Ruthenium Single‐Molecule Devices

Advanced Science, EarlyView.
An atomically precise platform was developed for investigating single‐molecule charge transport. This innovative platform enables the creation of highly uniform molecular devices using ruthenium‐based molecules. It reveals a significant enhancement in molecular conductance due to the metallic ruthenium center and a unique barrier‐lowering effect during

Deconvolution of the density of states of tip and sample through constant-current tunneling spectroscopy

Beilstein Journal of Nanotechnology, 2011
We introduce a scheme to obtain the deconvolved density of states (DOS) of the tip and sample, from scanning tunneling spectra determined in the constant-current mode (z–V spectroscopy).

Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

Advanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Ultrathin GaOx tunneling contact for 2D transition-metal dichalcogenides transistor

International Journal of Extreme Manufacturing
Interlayer insertion has emerged as one of the key strategies for contact engineering in two-dimensional (2D) field-effect transistors (FETs). However, conventional interlayers such as hexagonal boron nitride (hBN) have limitations in contact performance

Ferroelectric Devices for In‐Memory and In‐Sensor Computing

Advanced Science, EarlyView.
Inspired by biological systems, in‐memory and in‐sensor computing overcome von Neumann bottlenecks. Ferroelectric devices can mimic synaptic functions and sense stimuli like light or force, therefore are ideal for these paradigms. This review introduces the ferroelectric devices applied for in‐memory and in‐sensor computing, covering their structures ...

A novel approach for determining the peak-to-valley current ratio in nanomaterial devices

Results in Physics
The peak-to-valley current ratio (PVCR) was determined using a new method based on the transfer matrix technique. This method was applied to right-triangular (sawtooth) and rectangular nanomaterial double barrier diodes composed of GaAs-Ga1-yAlyAs ...

Air stable n-doping of WSe2 by silicon nitride thin films with tunable fixed charge density

APL Materials, 2014
Stable n-doping of WSe2 using thin films of SiNx deposited on the surface via plasma-enhanced chemical vapor deposition is presented. Positive fixed charge centers inside SiNx act to dope WSe2 thin flakes n-type via field-induced effect.
