High Frequency Devices Employing Non-Linear Ballistic and Hydrodynamic Transport Regimes Offer New Features and Improved Energy Efficiency

THE CHALLENGE: Current electronic devices are limited by electron transport speed Due to the limits of their materials, conventional electronics allow only diffusive electron transport motion and only in one dimension. Advances in material purity are allowing newly discovered ballistic and hydrodynamic electron transport regimes to be reached in solid...

Planar Bridging-Droplet Thermal Diodes

THE CHALLENGE Thermal diodes preferentially conduct heat in one direction but insulate in the reverse direction. They are of immense practical interest for smart thermal management of aircraft, electronics, and buildings. However, real-life implementation has been constrained by poor effectiveness (solid-state diodes), dependence on a gravitational...
