Abstract
The system and method for a metal meta-material embedded with a phase change material to form an optically induced phase change material. A metal doped polymer domain within the optically induced phase change material provides electric-field enhancement at the interface with a semiconductor domain and provides a thermal heat sink, to provide rapid thermal dissipation away from the semiconductor domain during the optical process.
