(PhysOrg.com) -- By connecting single nano-objects together, scientists can fabricate tiny solid-state devices through which a precisely controlled single-electron current can flow. In the past several years, scientists have ...
Chinese scientists have shown that magnetic memory, logic and sensor cells can be made faster and more energy efficient by using an electric, not magnetic, field to flip the magnetization of the sensing layer only about halfway, ...
