Abstract
The present invention provides vapor deposition methods that overcome the kinetic restrictions imposed by more conventional vapor deposition processes and liquid-cooling techniques to form amorphous molecular solids with greatly enhanced stabilities. The present methods produce amorphous molecular solids having stabilities, as measured by fictive temperature, that cannot be achieved using liquid-cooling methods.
