Teams from Stanford and the University of Nebraska-Lincoln have collaborated to make thin, transparent semiconductors that could become the foundation for cheap, high-performance displays.
The researchers used their new process to make organic thin-film transistors with electronic characteristics comparable to those found in expensive, curved-screen television displays based on a form of silicon technology.
Typically, teams drop a special solution, containing carbon-rich molecules and a complementary plastic, onto a spinning platter – in this case, one made of glass. The spinning action deposits a thin coating of the materials over the platter.
The collaborators made two important changes to this basic process. First, they spun the platter faster. Second, they only coated a tiny portion of the spinning surface, equivalent to the size of a postage stamp.
