Laptop computers can generate enough heat that, in rare cases, they actually catch fire. While engineers have a great grasp of how to control electrical charge in circuits, they have a hard time getting rid of the heat created by flowing electrons. Whats missing is a fundamental understanding of how individual electrons generate heat.
A new device developed by University of Wisconsin-Madison Electrical and Computer Engineering Associate Professor Robert Blick promises to change that. In addition, it will provide insights into harnessing quantum forces for communication and computing.
Blick, along with his graduate student Eva Hoehberger and colleague Werner Wegscheider, developed something similar to an incredibly small trampoline for bouncing individual electrons. It operates as an artificial atom, or a membrane, suspended over a semiconductor cavity.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
