Germanium-tellurium alloy could form basis for reconfigurable electronic switches

Decades of optimization have made the electronic switch both tiny and efficient. Yet engineers continue to adapt it to meet the increasingly demanding requirements of new applications. One such emerging requirement is the need for a switch to dissipate no power when it is off -- a condition that many existing compact switch designs cannot satisfy. Eng Keong Chua and co-workers at the A*STAR Data Storage Institute, Carnegie Mellon University and the Singapore University of Technology and Design have now designed a switch that draws power only during the act of switching.
