New Germanium-Based Material Could Replace Silicon for Electronics

New Germanium-Based Material Could Replace Silicon for Electronics

The old adage “what goes around comes around” is now being applied in electronics. Before silicon ruled the roost as the electronics material of choice, the first transistors were fashioned out of germanium . Now researchers at Ohio State University (OSU) are bringing germanium back to electronics in a way that they believe could displace silicon . To achieve its new role the researchers have manipulated the germanium down into a one-atom-thick material that gives it a two-dimensional structure not unlike graphene, thereby joining a growing list of 2-D materials targeted for electronic applications. The researchers say that electrons conduct through their germanium-based material ten times faster than through silicon and five times faster than in traditional germanium. Joshua Goldberger, assistant professor of chemistry at Ohio State, was attracted to the material because ...
