Device Physics: Topological transistor

Devices based on surface electrons in topological insulators are keenly anticipated, but singling these electrons out amid abundant bulk electrons poses a formidable challenge. Inspiration from the common transistor now enables manipulation of these exotic states, as demonstrated by Joseph Checkelsk...

Description
Summary:Devices based on surface electrons in topological insulators are keenly anticipated, but singling these electrons out amid abundant bulk electrons poses a formidable challenge. Inspiration from the common transistor now enables manipulation of these exotic states, as demonstrated by Joseph Checkelsky et al.
