Using Hummingbird Scientific Gas TEM holder and Gas Controller, researchers from Colorado School of Mines and National Renewal Energy Laboratory were able to demonstrate the crystallization behavior of amorphous titanium oxide thin films and understand the mechanism of metastable crystalline polymorph stabilization while annealing films deposited at various partial pressure of oxygen. The work reported in the Journal of the American Ceramic Society, presents insights into the process of controlling microstructure upon observing at various higher energy metastable phases.
