Handling materials in TRACER for group and individuals

Motivation:

Accurate Monte Carlo simulation of electron scattering in TRACER requires precise material definitions, but the default Material Archive does not always cover custom substrates, resists, or compound materials used in research. This creates a need for a flexible way to extend the material database while maintaining physical accuracy.

Solution:

This work explains how users can add, edit, and manage new materials in the TRACER Material Archive by defining key physical parameters such as mass density, stoichiometry, and excitation energy. By supporting both global and local material archives, the approach enables consistent simulations across teams while allowing individual customization when needed.
