A metastable alloy of carbon, germanium and tin, formed from well-defined stable molecular precursors. This material is predicted to have a direct bandgap and a lattice constant very close to that of silicon. |
Clever chemists have determined how to transfer unusual stoichiometries and bond geometries from novel CVD precursor molecules into the solid state. We are applying these advances to the design of new semiconductors. Some of these new allows combine interesting optical properties with very desirable lattice structures. Others may enable the creation of semiconducting materials with very high doping levels. This work was featured in Nature magazine. A video presentation of this topic is available.
