In the team's experimental setup, electricity was supplied to a tiny piece of tungsten selenide (small rectangle at center) through two gold wires (from top left and right), causing it to emit light (bright area at center), demonstrating its potential as an LED material. Inset: Microscope image shows the teams experimental setup. (Images courtesy of Britt Baugher and Hugh Churchill)
