Most of these materials are at the bottom of the convex hull i.e. in thermodynamic equilibrium. However, many functional materials are actually employed well above the hull, i.e. they are metastable. We will discuss our recent work to begin to address predictive computations for a number of kinds of metastability and their experimental realization. One class is polymorphic systems where higher energy polymorphs have both significant structural and functional differences than the ground state materials. Examples are the TiO2 system where rutile is the ground state but anatase is a better electronic material and brookite is a better catalyst. A second class is alloy systems such as ZnMnOx where it is possible to force the correct functional phases to get better functionality such as photo-electrochemical water splitting. A third class is control of the defects\/doping of semiconductor materials such as transparent conductive oxides like Ga2O3 where functionality depends on controlling the eliminating deleterious defects and enhancing the density of beneficial ones. We will discuss recent computational results and the experimental exploration of the computational predicted metastable materials that directly affect energy conversion.<\/p>\n<p>This work was funded by the Center for the Next Generation of Materials by Design, an<br \/>\nEnergy Frontier Research Center funded by the U.S. Department of Energy, Office of<br \/>\nScience, Basic Energy Sciences under Contract No. DE-AC36-08GO28308 to NREL.<\/p>\n<p><strong>Authors:<\/strong>\u00a0David Ginley<sup>1<\/sup>, Gebrand Ceder<sup>2<\/sup>, Kristin Persson<sup>2<\/sup>, Mike Toney<sup>3<\/sup>, Stephan Lany<sup>1<\/sup>, and William Tumas<sup>1<\/sup><br \/>\n<sup>1<\/sup>\u00a0National Renewable Energy Laboratory, Golden, CO 80401<br \/>\n<sup>2<\/sup>\u00a0Lawrence Berkeley National Labortory, Berkeley CA<br \/>\n<sup>3<\/sup>\u00a0SLAC National Accelerator Laboratory, Palo Alto CA<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Dr David Ginley Research Fellow\/ Chief Scientist.
