Chemists make new silicon-based nanomaterials
Providence RI (SPX) Apr 01, 2015
In a paper published in the journal Nanoletters, the researchers describe methods for making nanoribbons and nanoplates from a compound called silicon telluride. The materials are pure, p-type semiconductors (positive charge carriers) that could be used in a variety of electronic and optical devices. Their layered structure can take up lithium and magnesium, meaning it could also be used to make electrodes in those types of batteries. "Silicon-based compounds are the backbone of modern electronics ... read more
