Aluminium electrodes effect the operation of titanium oxide sol-gel memristors (2011)
Working Paper
Gale, E., Pearson, D., Kitson, S., Adamatzky, A., & de Lacy Costello, B. Aluminium electrodes effect the operation of titanium oxide sol-gel memristors

By a comparison between memristors made with aluminium and gold electrodes, this letter demonstrates that aluminium electrodes are an essential component of the TiO$_2$ sol-gel flexible memristor . Both slow varying `analogue' and sudden switching `d... Read More about Aluminium electrodes effect the operation of titanium oxide sol-gel memristors.
