Epitaxial thin film discovery could be promising
Researchers discover phenomenon in epitaxial thin film materials A team of researchers from the Oak Ridge National Laboratory in the U.S. have discovered a phenomenon in cobaltites that has eluded the scientific community for decades. This discovery could lead to new advances in fuel cell technology as well as a vast number of energy-related materials. The team, led by Ho Nyung Lee, believes that the discovery holds particular promise for hydrogen energy systems, which have long been plagued with inefficiencies. The discovery may put some of the skepticism surrounding fuel cells to rest. Disc…
Researchers discover phenomenon in epitaxial thin film materials
A team of researchers from the Oak Ridge National Laboratory in the U.S. have discovered a phenomenon in cobaltites that has eluded the scientific community for decades. This discovery could lead to new advances in fuel cell technology as well as a vast number of energy-related materials. The team, led by Ho Nyung Lee, believes that the discovery holds particular promise for hydrogen energy systems, which have long been plagued with inefficiencies. The discovery may put some of the skepticism surrounding fuel cells to rest.Discovery of phenomenon may change conventional wisdom
The discovery relates to a strain relaxation phenomenon in cobaltites that has long been the subject of speculation but has proven difficult to observe directly. Conventional wisdom suggests that defects must exist in epitaxial thin films in order for such materials to be stable while in the process of being formed. Researchers have now found that some materials, such as cobaltite, can form atomic structures capable of changing their magnetic polarity, thus adapting to the strain associated with forming epitaxial thin films and allowing for such materials to be created without defects.
