Reply To: Method to add Lithium Niobate Material in Lumerical Charge (Device) solver

As long as you know the materials belongs one of the three categories: insulator, metal and semiconductor, you can create new matgerials in CHARGE:

Semiconductor Material Model Properties

Tips for creating a new semiconductor material

Electrical/Thermal material models in CHARGE, HEAT, and MQW 

Thin Film Lithium Niobate Electro-Optic Phase Modulator

metals and insulators have much fewer parameters so you can follow the same procedure to add them.

 Since CHARGE simulates only the semiconductor materials, sometimes you will need to convert insulator/metal to be semiconductor by assign proper semiconductor material properties.
