Scientists collaborating on the project will apply their expertise and research to tunnel field effect transistors and semiconducting nanowires to improve the efficient use of energy in electronics.

To explain the challenge, consider a leaky water faucet — even after closing the valve as far as possible water continues to drip — this is similar to today’s transistor, in that energy is constantly "leaking" or being lost or wasted in the off-state.

In Steeper, scientists not only hope to contain the leak by using a new…

Catch and Stop-Energy Vampires
