Probing the quantum mechanics of magnetism is not for the faint of heart. Literally. The door to Madalina Furis’ laboratory on the fifth floor of the Cook Building has a sign that reads “Stop! No pacemakers beyond ...
The gallium nitride nanowires grown by PML scientists may only be a few tenths of a micrometer in diameter, but they promise a very wide range of applications, from new light-emitting diodes and diode lasers to ultra-small ...
(PhysOrg.com) -- In an effort to make computer chips even faster than those of today, many researchers have recently been investigating the possibility of optical computing. In an optical computer, information is encoded ...
By nestling quantum dots in an insulating egg-crate structure, researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated a robust new architecture for quantum-dot light-emitting devices ...
(PhysOrg.com) -- When it comes to fabricating stretchable, transparent electronics, finding a material to make transistors from has been a significant challenge for researchers. They've explored a variety of conventional ...
As the world has become less analog and more digital -- as tape decks and TV antennas have given way to MP3 players and streaming video -- electrical engineers’ habits of thought have changed, too. In the analog world, ...
Could Pittsburgh be the nation's next "Strontium Valley"? The University of Pittsburgh is the lead institution on a $1.8 million grant from the National Science Foundation and the Nanoelectronics Research Initiative (NRI) ...
Physicists from Umea University have found an efficient way to synthesize graphene nanoribbons directly inside of single-walled carbon nanotubes. The result was recently published in the scientific journal Nano Letters.
(PhysOrg.com) -- Since the first optical microscopes appeared in the late 1600s – an exact date and original inventor elude precise identification – microscopy has evolved dramatically. Scanning tunneling microscopy ...
Crystals can guide and control light and electricity by creating spatially periodic energy barriers. An electron (or photon) can pass through these barriers only when it has a particular energy, allowing engineers to ...
