In the search for silicon-compatible materials, aluminum scandium nitride (AlScN), which had already been flagged as an excellent piezoelectric\u2014referring to a material\u2019s ability to generate electricity when pressure is applied, or to deform when an electric field is applied\u2014has come to the fore. However, better control of its properties and means to enhance its electro-optic coefficients are still required.<\/p>\n<p>Researchers in Chris Van de Walle\u2019s computational materials group at UC Santa Barbara have now uncovered ways to achieve these goals. Their study, <a href=\"https:\/\/pubs.aip.org\/apl\/article\/126\/4\/041901\/3332365\/Towards-higher-electro-optic-response-in-AlScN\" target=\"_blank\">published<\/a> in <i><i>Applied Physics Letters<\/i>,<\/i> explains how adjusting the material\u2019s atomic structure and composition can boost its performance.
