Paper Title: Electrical characterisitcs of interfacial barriers at Metal - TiO2 contacts Authors: Loukas Michalas, Ali Khiat, Spyros Stathopoulos and Themistoklis Prodromakis Institution: University of Southampton Department: Zepler Institute for Photonics and Nanoelectronics Group: Electronic Materials and Devices Research Group Address: Highfield Campus, Southampton,SO17 1BJ, UK Corresponding Author: Loukas Michalas (l.michalas@soton.ac.uk) Period of data collection: September 2017 - July 2018 Manuscript Submitted: 15 June 2018 Revised Manuscript Submitted: 14 August 2018 Manuscript Accepted: 20 August 2018 Published at: Journal Of Physics D: Applied Physics (http://iopscience.iop.org/journal/0022-3727) Data DOI: https://doi.org/10.5258/SOTON/D0630 ............................................................................................................................................................................. This “read me” file aims to explain how the dataset file “Data for-Electrical characterisitcs of interfacial barriers at Metal - TiO2 contacts" should be analysed. This is an excel type file that consist of three (9) sheets. Each one of them contains the raw data presented in paper’s figures: 1c, 3a, 3b, 4a, 4b, 4c, 12a, 12b and 12d respectively. The symbols used have their usual meaning as: V: for voltage I: for current T: for the absolute temperature Veff: is explained in the text Eq.(1) X,Y,Z are the three dimesion Al, Ti, Ni, Au, Pt: are the corresponding chemical symbols for Aluminium, Titanium, Nickel, Gold and Platinum All the other plots/figures presented in the manuscript are generated by these raw data. Any additional information possibly required exist either on the plots or on the manuscript text.
