Here, using MgO-doped PPE:LN templates, we investigate the influence of the doping on the nanostructure formation as a function of the proton exchange (PE) depth. The deposition is found to occur preferentially along the boundary between MgO-doped LN and the PE region when the PE depth is at least 1.73 μm, however, for shallower depths, deposition occurs across the entire PE region. The results are found to be consistent with an increased photoconductivity of the MgO-doped LN.||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||AIP||Journal:||Applied Physics Letters||Volume:||103||Issue:||18||Start page:||182904||Copyright (published version):||2013 AIP Publishing LLC||Keywords:||Ferroelectric; Proton exchange; Photoreduction; Photoconductivity||DOI:||10.1063/1.4827541||Language:||en||Status of Item:||Peer reviewed|
