Effects of Interlayer Coupling on Hot Carrier Dynamics in Graphene-derived van der Waals Heterostructures
Prineha Narang, Litao Zhao, Steven Claybrook +1
Graphene exhibits promise as a plasmonic material with high mode confinement that could enable efficient hot carrier extraction. We investigate the lifetimes and mean free paths of…
Universal stability of two-dimensional traditional semiconductors
Michael C. Lucking, Weiyu Xie, Duk-Hyun Choe +3
Interest in two dimensional materials has exploded in recent years. Not only are they studied due to their novel electronic properties, such as the emergent Dirac Fermion in graphe…
Chalcogenide Perovskites- an Emerging Class of Ionic Semiconductors
Samanthe Pereraa, Haolei Huia, Chuan Zhao +11
We report the synthesis and characterization of a novel class of ionic semiconductor materials- inorganic chalcogenide perovskites. Several different compounds including BaZrS3, Ca…
Toward the intrinsic limit of topological insulator Bi2Se3
Jixia Dai, Damien West, Xueyun Wang +5
Combining high resolution scanning tunneling microscopy and first principle calculations, we identified the major native defects, in particular the Se vacancies and Se interstitial…
On the Nature of High Field Charge Transport in Reinforced Silicone Dielectrics: Experiment and Simulation
Yanhui Huang, Linda. S. Schadler
The high field charge injection and transport properties in reinforced silicone dielectrics were investigated by measuring the time-dependent space charge distribution and the curr…
Electron and phonon properties and gas storage in carbon honeycomb
Yan Gao, Yuanping Chen, Chengyong Zhong +3
A new kind of three-dimensional carbon allotropes, termed carbon honeycomb (CHC), has recently been synthesized [PRL 116, 055501 (2016)]. Based on the experimental results, a famil…
