Van der Waals Heterostructures for Next‐Generation Spintronics: Multiferroic‐Mediated Magnetoelectric Properties

Advanced Science, EarlyView.
As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

Van der Waals Gap‐Confined Molecular Engineering of MoS2 for Selectivity‐Enhanced and Humidity‐Tolerant Gas Sensing

Advanced Science, EarlyView.
Molecular confinement within van der Waals gaps of MoS2 is established as a powerful design strategy for selective and stable chemical sensing. Ethanol‐confined films simultaneously tune electronic doping, surface wettability, and sulfur vacancy configurations, suppressing water interference while enhancing NO2 adsorption.

One- and two-dimensional cuprous oxide nano/micro structures fabricated on highly orientated pyrolytic graphite (HOPG) by electrodeposition [PDF]

Electrochimica Acta, 2013
Abstract One- and two-dimensional cuprous oxide (Cu 2 O) nanostructures were fabricated on highly orientated pyrolytic graphite (HOPG) by electrodeposition in CuSO 4 at room temperature (25 °C) with no additives. For short deposition times, 1D Cu 2 O single nanocrystals were generally of an octahedral shape with sizes ranging from 50 nm to 400 nm ...

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.
A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.

Self-Assembly of Vertically Aligned Nanorod Supercrystals Using Highly Oriented Pyrolytic Graphite

, 2007
Supercrystallization of CdS nanorods (10 nm × 25 nm) into perpendicular superlattices was obtained by controlled evaporation of a nanorod solution trapped between a smooth substrate and a block of highly oriented pyrolytic graphite (HOPG).
