New research from materials scientist Chris Van de Walle illuminates the path to superior electro-optic performance in ...

explains how adjusting the material’s atomic structure and composition can boost its performance. Strong electro-optic response requires a large concentration of scandium — but the specific ...

“By using cutting-edge atomistic modeling, we found that placing scandium atoms in a regular array along a specific crystal axis greatly ... investigate superlattice structures, in which atomically ...

Their study, published in Applied Physics Letters, explains how adjusting the material's atomic structure and composition ... the scandium atoms within the AlN crystal lattice matters.

"By using cutting-edge atomistic modeling, we found that placing scandium atoms in a regular array along a specific crystal ... structures, in which atomically thin layers of ScN and AlN are ...

Project leader Professor Yoichi Murakami commented, "Although that structure was anticipated when I first looked at the layered morphology, I was excited when the results of the single-crystal X ...
