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.

Low-Power Quantum Computers

By 2017, quantum physics will help reduce the energy consumption of computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key issue. The next step will likely come from tunnel-FET, a technology that takes advantage of a phenomenon referred to as quantum tunneling. At the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, research is well underway.

Voltage Increases Observed in Closely Packed Nanowires

Unexpected voltage increases of up to 25 percent in two barely separated nanowires have been observed at Sandia National Laboratories. Designers of next-generation devices using nanowires to deliver electric currents — including batteries and certain solar arrays — may need to make allowances for such surprise boosts.
