Nanowire lawns make for sheets of image sensors

Abstract:
Growing a mixed "lawn" of two kinds of nanowires can make a new kind of light-sensing array that could be made in metre-scale sheets. The researchers behind the prototype say such cheap, high-quality image sensors would allow uses not conceivable using today's more expensive technology.

Current sensors, such as those found in digital cameras, are made like any other silicon chip - they are carved out from a block of material. The new nanowire sensors are instead built from the bottom up, using chemically-grown nano-sized components.

A research team led by Ali Javey, at the University of California, Berkeley, developed the process. They start by growing an unruly "lawn" of nanowires on a surface.
