La2YbCuS5
semiconductor· La2YbCuS5
La2YbCuS5 is a rare-earth transition-metal chalcogenide compound containing lanthanum, ytterbium, copper, and sulfur. This is primarily a research-phase material being studied for semiconducting and photovoltaic applications, particularly in the broader family of ternary and quaternary sulfide semiconductors that offer tunable band gaps and potential for optoelectronic device integration. The material's combination of rare-earth and transition-metal elements positions it as a candidate for next-generation thin-film photovoltaics, photocatalysis, or thermoelectric systems where conventional semiconductors like silicon or CdTe may be limiting.
