Materials science researchers develop first electrically injected laser

Posted by in categories: computing, science

Materials science researchers, led by electrical engineering professor Shui-Qing “Fisher” Yu, have demonstrated the first electrically injected laser made with germanium tin.

Used as a semiconducting material for circuits on , the could improve micro-processing speed and efficiency at much lower costs.

In tests, the laser operated in pulsed conditions up to 100 kelvins, or 279 degrees below zero Fahrenheit.
