Researchers first to create a single-molecule diode
Under the direction of Latha Venkataraman, associate professor of applied physics at Columbia Engineering, researchers have designed a new technique to create a single-molecule diode, and, in doing so, they ...
Researcher charts quantum signatures of electronic transport in graphene
Over the last seven years, Javier Sanchez-Yamagishi has built several hundred nanoscale stacked graphene systems to study their electronic properties. "What interests me a lot is that the properties of this ...
Researchers find a way of tuning light waves by pairing two exotic 2-D materials
Researchers have found a way to couple the properties of different two-dimensional materials to provide an exceptional degree of control over light waves. They say this has the potential to lead to new kinds ...
Wearables may get boost from boron-infused graphene
A microsupercapacitor designed by scientists at Rice University that may find its way into personal and even wearable electronics is getting an upgrade. The laser-induced graphene device benefits greatly ...
Electrons corralled using new quantum tool
Researchers have succeeded in creating a new "whispering gallery" effect for electrons in a sheet of graphene—making it possible to precisely control a region that reflects electrons within the material. ...
Channeling valleytronics in graphene: Researchers discover 1-D conducting channels in bilayer graphene
To the list of potential applications of graphene – a two-dimensional semiconductor of pure carbon that is stronger and much faster than silicon – we can now add valleytronics, the coding of data in the ...
Electron chirp: Cyclotron radiation from single electrons measured directly for first time
A year before Albert Einstein came up with the special theory of relativity, or E=mc2, physicists predicted the existence of something else: cyclotron radiation. Scientists predicted this radiation to be ...
Samsung details a dual-OS phone-docking hybrid device
Physicists solve quantum tunneling mystery
An international team of scientists studying ultrafast physics have solved a mystery of quantum mechanics, and found that quantum tunneling is an instantaneous process.
Research could lead to biodegradable computer chips
Portable electronics - typically made of non-renewable, non-biodegradable and potentially toxic materials - are discarded at an alarming rate in consumers' pursuit of the next best electronic gadget.
Mission possible: This device will self-destruct when heated
Where do electronics go when they die? Most devices are laid to eternal rest in landfills. But what if they just dissolved away, or broke down to their molecular components so that the material could be recycled?
Tech firms, activists press US on encryption
Some 140 tech companies, civil liberties and privacy activists urged the White House Tuesday to pull back efforts to weaken encryption or include law enforcement "backdoors" on technology products.
Researchers create first hidden, real-time, screen-camera communication
Opening the way for new applications of smart devices, Dartmouth researchers have created the first form of real-time communication that allows screens and cameras to talk to each other without the user knowing ...
Scientists discover how microbes acquire electricity in making methane
Stanford University scientists have solved a long-standing mystery about methanogens, unique microorganisms that transform electricity and carbon dioxide into methane.
