Resumen:
BaBiO3 is a charged ordered Peierls-like perovskite well known for its superconducting propertiesupon K or Pb doping. We present a study on the transport and electronic properties of BaBiO3 perovskite with strong Bi-deciency. We show that it is possible to synthesize BaBiO3 thin layers withBi-vacancies above 8-10% by depositing an yttrium-stabilized zirconia capping layer. By combiningtransport measurements with ab initio calculations we propose an scenario where the Bi-vacanciesgive rise to the formation of polarons and suggest that the electrical transport is dominated by themigration of these polarons trapped at Bi3+ sites. Our work shows that cation vacancies engineering-hardly explored to date- appears as a promising pathway to tune the electronic and functionalproperties of perovskites.
