· Na2TeSe3

Na₂TeSe₃ is a mixed chalcogenide semiconductor compound combining sodium, tellurium, and selenium elements, representing an emerging class of materials in the broader family of quaternary and polyelemental semiconductors. This compound is primarily investigated in research contexts for optoelectronic and photovoltaic applications, where its tunable bandgap and layered crystal structure offer potential advantages in solar cells, photodetectors, and other light-responsive devices compared to binary or ternary semiconductors. The substitution of selenium and tellurium provides compositional flexibility to engineer electronic properties, making it of interest to researchers developing next-generation thin-film photovoltaics and emerging semiconductor technologies.
