Electronic Confinement and Coherence in Patterned Epitaxial Graphene
Ultrathin epitaxial graphite was grown on single-crystal silicon carbide by vacuum graphitization. The material can be patterned using standard nanolithography methods. The tran...

Deep Sparse Rectifier Neural Networks
While logistic sigmoid neurons are more biologically plausible than hyperbolic tangent neurons, the latter work better for training multi-layer neural networks. This paper shows...
High-Thermoelectric Performance of Nanostructured Bismuth Antimony Telluride Bulk Alloys
The dimensionless thermoelectric figure of merit (ZT) in bismuth antimony telluride (BiSbTe) bulk alloys has remained around 1 for more than 50 years. We show that a peak ZT of ...
Surface-enhanced spectroscopy
In 1978 it was discovered, largely through the work of Fleischmann, Van Duyne, Creighton, and their coworkers that molecules adsorbed on specially prepared silver surfaces produ...
Light-Induced Redox Reactions in Nanocrystalline Systems
A review with 156 refs. on interfacial electron transfer reactions in colloidal semiconductor solns. and thin films and their application for solar light energy conversion and p...
A fracture-resistant high-entropy alloy for cryogenic applications
A metal alloy that is stronger when cold Metal alloys normally consist of one dominant element, with others in small amounts to improve specific properties. For example, stainle...
