New Approach to Graphene Electronics

Graphene has been touted as the next silicon, but it is too conductive to be used in computer chips. A University of Manchester team led by Nobel laureates Professor Andre Geim and Professor Konstantin Novoselov has literally opened a third dimension in graphene research.

Welding Nanowires With Light

Electrically conductive meshes made of metal nanowires promise exceptional electrical throughput, low cost, and easy processing in applications like video displays, LEDs, and thin-film solar cells. However, in processing, these meshes must be heated or pressed to unite the crisscross pattern of nanowires that form the mesh - damaging them in the process.

Quantum Dot Light Enhancement Substrate

A cost-competitive solution for increasing the light extraction efficiency of organic light-emitting diodes (OLEDs) with efficient and stable color rendering index (CRI) for solid-state lighting (SSL) was developed and demonstrated. Solution-processable quantum dot (QD) films were integrated into OLED indium tin oxide (ITO)-glass substrates to generate tunable white emission from blue-emitting OLED devices.

Fully Printed Carbon Nanotube Transistor Circuits for Displays

Organic light-emitting diode (OLED)-based displays are used in cell phones, digital cameras, and other portable devices. But developing a lower-cost method for mass-producing such displays has been complicated by the difficulties of incorporating thin-film transistors that use amorphous silicon and polysilicon into the production process.
