I am interested in the optical devices based on 2D materials. For modeling 2D material, I am trying to import the sampled data for conductivity by using the “sampled 2D data” option in Material Database.
Whenever I try to fit sampled data in Material Explorer after creating new material and importing data from text file, however, I repeatedly got error message saying “The program terminated due to: unknown error Please contact Lumerical technical support for assistance” and Lumerical was terminated automatically.
I have any idea of why this happens.
Attached is the text file containing the real (column 2) and imaginary (column 3) parts of conductivity as a function of wavelength (column 1), which I used to create new material.
Would you please let me know how to solve this problem??
