Nanowire Heterostructures Form Tunneling Diodes

Daniel S. Burgess

Continuing their research into nanoscale semiconductor heterostructures known as nanowires, a team at Lund University in Sweden has produced one-dimensional resonant tunneling diodes that display nearly ideal current-to-voltage characteristics. The devices, which electrically address a single quantum dot, herald nano-optoelectronics of improved performance. Lund University researchers have constructed resonant tunneling diodes using one-dimensional semiconductor heterostructures. A micrograph of the nanowire device (a) illustrates the double-barrier geometry (scale bar is 30 nm). The...Read full article
