      abstract     = {The wake-up effect in yttrium doped hafnium oxide is
                      investigated by pulse measurements, revealing the initial
                      distribution of oxygen vacancies within symmetrical and
                      asymmetrical layer stacks. It is shown that single pulses
                      are sufficient to achieve a significant wake-up, whereby
                      additional pulses lead to a stronger wake-up. Further
                      cycling induces a degradation of the devices, which is
                      explained by generation of oxygen vacancies and results in
                      an electroforming step where subsequently resistive valence
                      change mechanism switching is observed. The degradation and
                      therefore the generation of oxygen vacancies show a strong
                      frequency dependence, whereby the device lifetime is
                      strongly increased for increasing frequencies},
