Flexible correlated 4d2 SrMoO3/mica thin films with enhanced optoelectronic performance and high bending stability

Recently, correlated metallic oxide (CMO) was proposed as a brand-new design strategy for transparent conductors (TCs). Among these CMOs, perovskite-type SrVO3 with an electronic configuration of 3 d1 has been most investigated. Herein, the SrMoO3 films, one 4 d2 perovskite CMO, were deposited on a...

Description
Summary:Recently, correlated metallic oxide (CMO) was proposed as a brand-new design strategy for transparent conductors (TCs). Among these CMOs, perovskite-type SrVO3 with an electronic configuration of 3 d1 has been most investigated. Herein, the SrMoO3 films, one 4 d2 perovskite CMO, were deposited on a flexible mica substrate using a pulsed laser deposition method. Our experimental results indicate that the SrMoO3 film possesses a superior optoelectronic performance compared with SrVO3, owing to the weaker electronic correlations and 4 d2 electronic configuration in SrMoO3. Bending cyclic tests indicate that the flexible SrMoO3/mica film has a high mechanical bending durability and stability. This 4 d2 SrMoO3/mica film demonstrates a great potential as a high-performance TC for flexible optoelectronics.
