Nanoclusters
like fullerenes as the unit to build intriguing two-dimensional
(2D) topological structures is of great challenge. Here we propose
three bridged fullerene monolayers and comprehensively investigate
the novel fullerene monolayer (α-C60-2D) as synthesized
experimentally [Nature2022606507510] by state-of-the-art first-principles calculations. Our results show that α-C60-2D has a direct band gap of 1.55 eV close to the experimental
value, an optical linear dichroism with strong absorption in the long-wave
ultraviolet region, a small anisotropic Young’s modulus, a
large hole mobility, and an ultrahigh Seebeck coefficient at middle–low
temperatures. It is unveiled that the anisotropic optical, mechanical,
electrical, and thermoelectric properties of α-C60-2D originate from the asymmetric bridging arrangements between C60 clusters. Our study promises potential applications of monolayer
fullerene networks in lots of fields.
High-throughput screening and material informatics have shown a great power in novel materials discovery including batteries, high entropy alloys, photocatalysts, etc. However, the lattice thermal conductivity (κ) oriented high-throughput screening...
Two-dimensional materials have attracted lots of research interests due to the fantastic properties that are unique to the bulk counterparts. In this paper, from the state-of-the-art first-principles, we predicted the...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
