Stone Cold Steve Austin was recently announced for WWE World in Las Vegas during WrestleMania weekend. The Texas Rattlesnake broke his silence after this announcement via his Instagram story.

Built using bismuth oxyselenide (Bi₂O₂Se), a high-mobility 2D material, the transistor operates at lower voltages and could enable ultra-dense chip designs with better performance per watt.

The method can be applied to any metal with a low melting point, and the team has used it to make 2D sheets of bismuth, gallium, indium, lead and tin. The feat was reported today in Nature 1.

Well, the Peking team has used bismuth in both the semiconductor and high-dielectric oxide. It's a post-transitional metal, which also applies to lead, gallium, indium and tin, among others.
