This “read me” file aims to explain how the dataset file “Data for-Interface asymmetry induced by symmetric electrodes on Metal-AlTiOx-Metal structures should be analysed. This is an excel type file that consist of three (3) sheets. Each one of them contains the raw data presented in paper’s figures: 2a, 2b and 2c respectively. The symbols used have their usual meaning as: V: for voltage I: for current T: for the absolute temperature 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 on the manuscript text.
