Leading the Charge:Exotic New Materials for Future Devices
How will we improve computer technology to create chips that are smaller, faster, and more efficient? For leaps in performance, we need to create new types of semiconductors. In this lecture, the speaker will describe a new class of materials -- the "topological insulators" -- that achieve robust performance by tying the paths of electrons in knots. These materials arose from a bold theoretical proposal that was recently verified by X-ray experiments at SLAC. THe speaker will describe the special properties of these materials and the promise for their applications.
