With some careful twisting and stacking, MIT physicists have revealed a new and exotic property in “magic-angle” graphene: superconductivity that can be turned on and off with an electric pulse, much ...
When it comes to graphene, it appears that superconductivity runs in the family.
MIT physicists have observed signs of a rare type of superconductivity in a material called magic-angle twisted trilayer graphene. In a study appearing today in Nature, the researchers report that the...
NSF-funded research by scientists at Brown and Columbia Universities has demonstrated the existence of previously unknown states of matter that arise in double-layer stacks of graphene, a two-dimensio...
A team led by Cory Dean, assistant professor of physics at Columbia University, and James Hone, Wang Fong-Jen Professor of Mechanical Engineering at Columbia Engineering, has definitively observed an ...
A material scientist at Michigan Technological University invented a novel approach to take carbon dioxide and turn it into 3-D graphene with micropores across its surface. The process is the focus of...
A little fluorine turns an insulating ceramic known as white graphene into a wide-bandgap semiconductor with magnetic properties. Rice University scientists said that could make the unique material su...
An international team of physicists, led by researchers at the University of Arkansas, has observed spontaneous mechanical buckling in freestanding graphene using scanning tunneling microscopy, indica...
In the quest to harvest light for electronics, the focal point is the moment when photons — light particles — encounter electrons, those negatively-charged subatomic particles that form the basis of o...
CHAMPAIGN, Ill. — When Illinois researchers set out to investigate a method to control how DNA moves through a tiny sequencing device, they did not know they were about to witness a display of molecul...
Uinversity of Illinois at Chicago researchers have discovered a way to create a highly sensitive chemical sensor based on the crystalline flaws in graphene sheets. The imperfections have unique electr...
FAYETTEVILLE, Ark. – An international team of physicists, led by a research group at the University of Arkansas, has discovered that heating can be used to control the curvature of ripples in freestan...
Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at...
原子尺度的碳单层(graphene)结构具有独特的光电转换性质。通过纳米加工制备的光学天线与碳单层构成的复合结构,可以有效地提高光电转换效率。近日,凝聚态所朱星教授团队的方哲宇百人计划研究员和美国Rice大学P. Nordlander, N. Halas教授合作,加工制备了两层碳单层之间的纳米尺度光学天线,这种三明治结构的光电探测器可以有效地用于可见光及近红外区域碳单层光电器件探测,光电流增强效应...
Graphene-based sp2-carbon nanostructures such as carbon nanotubes and nanofibers can fail near their ideal strengths due to their exceedingly small dimensions. We have calculated the phonon spectra ...
