Scientists produce a novel form of artificial graphene

A new breed of ultra thin super-material has the potential to cause a technological revolution. "Artificial graphene" should lead to faster, smaller and lighter electronic and optical devices of all kinds, including higher ...

Growing gallium nitride crystals

Gallium nitride (GaN) is an important material for the semiconductor industry. It features a wide band gap and high thermal conductivity at room temperature, which make it a good material for optoelectronic devices and high-performance ...

Gadget genius

University of Akron researchers have developed new materials that function on a nanoscale, which could lead to the creation of lighter laptops, slimmer televisions and crisper smartphone visual displays.

New family of tiny crystals glow bright in LED lights

(Phys.org) —Minuscule crystals that glow different colors may be the missing ingredient for white LED lighting that illuminates homes and offices as effectively as natural sunlight.

Researchers work to improve mechanical stability of nanofilms

(Phys.org)—Read heads in hard drives, lasers in DVD players, transistors on computer chips, and many other components all contain ultrathin films of metal or semiconductor materials. Stresses arise in thin films during ...

Discovery of new colossal magnetoresistance mechanism

A NIMS research group has discovered a new material, NaCr2O4, which displays a novel type of colossal magnetoresistance effect. The new material was developed by ultra-high pressure synthesis.

Nanocrystal infrared LEDs can be made cheaply

(Phys.org) -- Light-emitting diodes at infrared wavelengths are the magic behind such things as night vision and optical communications, including the streaming data that comes through Netflix. Cornell researchers have advanced ...

Conquering LED efficiency droop

WASHINGTON, April 30--Like a coffee enthusiast who struggles to get a buzz from that third cup of morning joe, light-emitting diodes (LEDs) seem to reach a point where more electricity no longer imparts the same kick and ...
