Crystals Now can be Used as Reusable Electrical Conductors
Scientists at the Washington State University have conducted several experiments on crystals, resulting in the discovery of a method that makes transparent crystals capable of conducting electricity, according to an article published in the Nature journal on July 27, 2017.
Researchers have observed that only on providing extra heat to crystals was it possible for them to conduct electricity, and once cooled, these crystals lost their effect within days.
The team, however, was successful at introducing electric conductivity into the crystals at room temperature. This was possible with the help of light, which was accidentally discovered four years ago. Scientists have now studied that light can increase the electric conductivity of crystals by a thousand times, effects of which persist for around a year.
To modify this, a line was engraved into the crystal with the help of a laser, after placing electrical contacts at both ends of the line, the crystal carried current.
According to Matt McCluskey, who is one of the authors in the study, the crystals can be compared to the mechanical drawing toy – Etch-a-Sketch. The effects are configurable and the crystal is transparent, similar to an etch-a-sketch. These crystals could be use in the future as invisible electronics or as windows.
The circuit can only be erased if heated at a high temperature on a hot plate, making it impractical for a window. However, the idea of invisible computers in laboratories could be a reality with the help of this discovery.
In this manner crystals could be made to conduct electricity, with effects lasting for up to a year with no degradation, making them effective, reusable means of electricity.
