ScholarBank@NUS Repository. https://doi.org/10.1007/s00339-011-6531-9||Abstract:||The leakage behaviors of ferroelectric layered-perovskite (Bi 3.15Nd 0.85)Ti 3O 12 (BNdT) thin films deposited on Pt/TiO 2/Ti/Si substrates by RF sputtering have been carefully investigated. Their I-V curves exhibit a rich diversity of conducting behaviors at different temperature and voltage ranges, which may be accounted for by various conducting mechanisms, including Ohmic behavior, Schottky emission, space-charge-limited current (SCLC), and Fowler-Nordheim tunneling effects. Their time-dependent leakage currents show a nearly linear relationship with respect to logarithmic relaxation time at initial stage (400 s) showing characteristics of ionic space-charge limit current relaxation. © 2011 Springer-Verlag.||Source Title:||Applied Physics A: Materials Science and Processing||URI:||http://scholarbank.nus.edu.sg/handle/10635/115168||ISSN:||09478396||DOI:||10.1007/s00339-011-6531-9|
