Abstract

Layered oxides have been intensively studied due to their high degree of freedom in designing various electromagnetic properties and functionalities. While Bi-based layered supercell (LSC) compounds [Bi $_{n}$ O $_{n + δ}$ ]-[ $M$ O $_{2}$ ] ( $M$ = Mn, Mn/Al, Mn/Fe, or Mn/Ni; $n = 2, 3$ ) are a group of prospective candidates, all of the reported compounds are insulators. Here, we report on the synthesis of two novel metallic LSC compounds [Bi $_{n}$ O $_{n + δ}$ ]-[RhO $_{2}$ ] ( $n = 2, 3$ ) by pulsed laser deposition and subsequent annealing. With tuning the thickness of the sublattice from Bi $_{2}$ O $_{2 + δ}$ to Bi $_{3}$ O $_{3 + δ}$ , a dimensionality-dependent electrical transport is revealed from a conventional metallic transport in $n = 2$ to a localized transport in $n = 3$ . Our successful growth will be an important step for further exploring novel layered oxide compounds.
