Diamond surface electrons could power smaller, cooler electronics

Diamond surface electrons could power smaller, cooler electronics

Hydrogen-terminated diamond-like carbon becomes more electrically responsive near its surface, unlike silicon, which weakens at the edge. The unusual boost appears to come from nearly free electrons that extend beyond the carbon surface and shift easily in an electric field. Atomic-scale maps could help researchers design thinner electronic materials, although the link between these surface electrons and the electrical boost still needs more stu…
