(Phys.org)—For many electronic devices, colder is better. At low temperatures, electronic devices such as sensors and detectors operate with a higher efficiency and better overall performance than they do at room temperature. ...
A new electrical method to conveniently change the direction of electron flow in some quantum materials could have implications for the development of next-generation electronic devices and quantum computers.

Tightening a string, e.g. when tuning a guitar, makes it vibrate faster. But when strings are nano-sized, increased tension also reduces, or 'dilutes', the loss of the string's vibrational modes.
