Shoucheng Zhang | Electron Superhighway: A Quantum Leap for Computing
Δημοσιεύτηκε στις 1 Φεβ 2017
For
the past 60 years, progress in information technology has been governed
by Moore's law, which states that the number of transistors on a
semiconductor chip doubles every 18 months. However, this remarkable
trend is drawing to a close, mostly because the electrons that carry
current in chips move like cars driving through a crowded marketplace,
swerving around obstacles and dissipating too much of their energy as
heat. The recent discovery of a new state of matter "the topological
insulator" may lead to a new paradigm of information processing, in
which electrons moving in opposing directions are separated into
well-ordered lanes, like automobiles on a highway. This talk will
explain the basic principles behind this amazing discovery.
