Excellent microwave absorption performance can be achieved by controlling the dielectric constant. Heteroatom-doped bimetallic materials are promising electromagnetic wave absorption (EMA) materials due to their tunable structures and low cost. In particular, the presence of anionic sites significantly affects their dielectric constant and electrical conductivity.

Subsequently, tellurization, vulcanization, and selenization processes are carried out.
