Electrical studies on perovskite BaSnO3 nanostructures

Abstract

Electric double layer gate controlled non-linear transport in a nanostructured functional perovskite oxide film Appl. Phys. Lett. 104, 083515 (2014); 10.1063/1.4867081Scanning tunneling microscope study of electrical transport properties of nanoscale Schottky contacts between manganese silicide nanostructures and Si (111) Abstract. Perovskite barium stannate (BSO) nanostructures (NS) were prepared by wet chemical method. The structural and optical properties were investigated by XRD, SEM and UV-Vis spectroscopy, respectively. The absorption spectrum exhibits a band gap of 4.1 eV, which is blue shifted from bulk. Polarization hysteresis (P-E) of BSO nanomaterial shows anti-ferroelectric behavior. The nanomaterial showed drastic enhancement in dielectric constant, nearly 1300 times higher than that of already reported values and this is achieved at room temperature (RT) itself.
