Good find. Maybe the theoretical work will finally catch up with the experimental.
I saw this sort of thing with the blue laser competitors ~ neighbor kid got into it early and even earned a doctorate in physics so he could join a research team that could come up with one that worked ~ billions were to be made.
Billions weren't made, but we do have blue laser electronic gear ~ and near-ultraviolet devices in use in industry. So, what are all those physicists doing who lost that race.
