The electronic state of thin films of yttrium, yttrium hydrides and yttrium oxide [PDF]
Solar Energy Materials and Solar Cells, 2014 Thin films of yttrium hydride have for almost 20 years been under investigation for optoelectronic and solar energy applications due to the hydrogen-induced switching in electronic state from the metallic elemental yttrium and yttrium dihydride to the transparent semiconductor material yttrium trihydride.
