Ho2 Ag2 Te4
semiconductor· Ho2 Ag2 Te4
Ho₂Ag₂Te₄ is a ternary intermetallic semiconductor compound combining holmium, silver, and tellurium in a layered crystal structure. This material is primarily of research interest rather than established commercial use, investigated for potential thermoelectric and optoelectronic applications where the rare-earth holmium component and narrow bandgap characteristics may offer advantages in energy conversion or photonic devices.
