Of course, freeing electrons in a copper - oxide insulator to get superconducting current flowing for useful applications won't be quite as easy as melting ice to get liquid water or removing pieces from a chessboard.

Many of these candidates are completely hypothetical, but engineers are already beginning to shortlist those that are worth synthesizing and testing for specific applications by searching through their predicted properties — for example, how well they will work as a conductor or an insulator, whether they will act as a magnet, and how much heat and pressure they can withstand.

For each semiconductor, we can find an appropriate insulator, which allows to achieve the same efficiency level as in double - heterostructure lasers.

This is especially important because quantum correlations play a crucial role in many, seemingly unrelated physics questions: Examples are the peculiar behaviour of the young universe right after the big bang, but also for special new materials, such as the so - called topological insulators.
