Semiconductors move to film

A TEAM of boffins at the University of Wisconsin-Madison have worked out ways of creating semi-conductors on thin film.

According to the Journal of Applied Physics, which we get for the crossword, the team, led by electrical and computer engineer Jack Ma and Max Lagally, have managed to remove a single-crystal film of semiconductor from the substrate on which it is built.

This thin layer can be transferred to glass, plastic or other flexible materials. It can also be flipped over making its other side available for more components.

Layers of double-sided, thin-film semiconductors can be stacked so that they create powerful devices which use less power.
