· RuSe2

RuSe₂ is a transition metal dichalcogenide semiconductor compound combining ruthenium and selenium, part of an emerging class of materials being investigated for next-generation electronic and optoelectronic devices. This material remains primarily in the research phase, with potential applications in high-performance semiconductors, photocatalysis, and energy conversion systems where its layered crystal structure and tunable bandgap could offer advantages over conventional silicon-based or established chalcogenide alternatives. Engineers considering RuSe₂ are typically exploring it for specialized applications requiring chemical stability, semiconducting properties, or catalytic activity rather than as a drop-in replacement for mature semiconductor technologies.
