Semiconductors doped with magnetic ions, also known as dilute magnetic semiconductors, are both semiconducting and ferromagnetic. It remains unclear, however, whether this ferromagnetism is ...

A recent article in Light: Science & Applications explores the enhancement of optical nonlinearities in plasmonic semiconductor nanostructures, focusing on heavily doped semiconductors. The ...

The scientists have experimentally demonstrated that ultrafast optical nonlinearities in doped semiconductors can be engineered and can easily exceed those of conventional undoped dielectrics.
