Beyond Silicon: Crystal Bismuth Quantum Liquid

"High switching rates and moving electrical charges around is the heart of electronic computing, and the crystal bismuth quantum liquid shows much potential. This could give way to faster microchips and more reliable, efficient computers."

Interesting to note that in some science fiction stories, there exists circuitry based on many kinds of elements. The most interesting I read up on was the idea of macrocircuits - in essence, whole buildings, or even architectural sites, functioning as large-scale circuit boards.
