The new bismuth-based transistor could revolutionize chip design, offering higher efficiency while bypassing silicon’s limitations.

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.
