The intercalation of lithium ions into layered materials has been an important field of research, leading not only to the development of lithium-ion batteries but also to countless insights in solid-state physics. Recently, it was shown that the intercalation of the quasi-1D semiconductor CrSBr can drastically alter its electronic structure, enhancing conductivity and potentially causing a transition from semiconductor to metal. Since the location and degree of intercalation can be precisely controlled, it allows us to fabricate devices using partially or fully intercalated CrSBr, harnessing properties of both the pristine and intercalated phases. Here we present a self-driven photodetector based on intercalated CrSBr, demonstrating high photoresponsivity across the entire NUV to NIR range with a response time in the millisecond range. Our findings not only deepen the understanding of intercalation effects in low-dimensional materials but also pave the way for the development of advanced optoelectronic devices using intercalated CrSBr.
