Abstract

Researchers report the growth of monolayer antimonene on a 2D layered PdTe2 substrate by molecular beam epitaxy (MBE). The researchers chose PdTe2 as the substrate for at least two reasons. Its crystal periodicity has a very small mismatch with that of freestanding antimonene. It has a chemically stable surface, typical of a layered transition-metal-dichalcogenide (TMD) material. The antimony atoms are first deposited onto a PdTe2 surface kept at a proper temperature, whereupon a distinct well-ordered structure is observed by in situ low-energy electron diffraction (LEED) PdTe2.
