A Holistic Stabilization of the Anode in Lithium‐Sulfur Batteries Through a Ternary Alloy Fusion

Advanced Functional Materials, EarlyView.
LiTeAl anodes fabricated through a scalable thermal fusion technique holistically addresses the stability issues faced by lithium‐metal anodes in lithium–sulfur batteries. Aluminum forming a skeletal network with lithium suppresses dendrite growth and enhances energy density, while tellurium forming a robust SEI facilitates Li+‐ion flow.

Valence band offset of MgO/4H-SiC heterojunction measured by x-ray photoelectron spectroscopy

, 2008
The valence band offset (VBO) of MgO (111)/4H-SiC heterojunction has been directly measured by x-ray photoelectron spectroscopy. The VBO is determined to be 3.65 +/- 0.23 eV and the conduction band offset is deduced to be 0.92 +/- 0.23 eV, indicating ...

Band Alignments, Band Gap, Core Levels, and Valence Band States in Cu3BiS3 for Photovoltaics [PDF]

, 2019
The earth-abundant semiconductor Cu3BiS3 (CBS) exhibits promising photovoltaic properties and is often considered analogous to the solar absorbers copper indium gallium diselenide (CIGS) and copper zinc tin sulfide (CZTS) despite few device reports.

Trace Sulfur‐Doping Boosts NiCo Heterostructured Catalyst for Selective Glycerol‐to‐Formic Acid Electroreforming

Advanced Functional Materials, EarlyView.
A sulfur‐doped Ni–Co heterostructured catalyst is rationally designed to regulate interfacial electronic and adsorption properties for selective glycerol electrooxidation. The synergistic Ni–Co active sites promote hydroxide activation and glycerol adsorption, enabling efficient formic acid production and durable hydrogen generation under continuous ...

Field emission of lower energy valence band electrons from 2-dimensional materials [PDF]

APL Electronic Devices
Vertical field emission for two-dimensional (2D) materials was normally assumed to have dominant emission by the conduction band electrons near to the Fermi surface with a linear scaling of ln(J/Fβ) ∝ 1/F and β = 1, which is different from the classical ...
