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 ...

S-t-r-e-t-c-h-i-n-g electrical conductance to the limit

Individual molecules have been used to create electrical components like resistors, transistors and diodes, that mimic the properties of familiar semiconductors. But according to Nongjian (NJ) Tao, a researcher at the Biodesign ...

Bright future for gaN nanowires

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 ...

Researchers advance toward hybrid spintronic computer chips

Researchers here have created the first electronic circuit to merge traditional inorganic semiconductors with organic "spintronics" – devices that utilize the spin of electrons to read, write and manipulate data.

New equation could advance research in solar cell materials

(PhysOrg.com) -- A groundbreaking new equation developed in part by researchers at the University of Michigan could do for organic semiconductors what the Shockley ideal diode equation did for inorganic semiconductors: help ...

New laser -- it's a gas, gas, gas... sensor

(PhysOrg.com) -- A new generation of optical sensors is enabling the development of robust, long-lasting, lighting-fast trace gas detectors for use in a wide range of industrial, security and domestic applications.
