Optics.org reported on the use of rare earths to develop less expensive solid state lighting technology.
The market news is quoted as saying:
The big problem is that the crystal structures of GaN and silicon are pretty incompatible, meaning that a strain-balancing buffer layer of semiconductor material typically has to be grown between the two. Where the new approach is different is that it integrates layers of a rare-earth-oxide within the LED structure.
