Since, on the one hand, many recent reports utilize TiO(2) for their studies of the memristive phenomenon and, on the other hand, there is a long history of the electronic structure and the crystallographic structure of TiO(2) under the impact of reduction and oxidation processes, we selected this material as a prototypical material to provide deeper insight into the mechanisms behind memristive switching. In part I, we briefly outline the results of the historical and recent studies of electroforming and resistive switching of TiO(2)-based cells. We describe the (tiny) stoichiometrical range for TiO(2 - x) as a homogeneous compound, the aggregation of point defects (oxygen vacancies) into extended defects, and the formation of the various Magnéli phases. Furthermore, we discuss the driving forces for these solid-state reactions from the thermodynamical point of view. In part II, we provide new experimental details about the hierarchical transformation of TiO(2) single crystals into Magnéli phases, and vice versa, under the influence of chemical, electrical and thermal gradients, on the basis of the macroscopic and nanoscopic measurements. Those include thermogravimetry, high-temperature x-ray diffraction (XRD), high-temperature conductivity measurements, as well as low-energy electron diffraction (LEED), x-ray photoelectron spectroscopy (XPS), and LC-AFM (atomic force microscope equipped with a conducting tip) studies. Conclusions are drawn concerning the relevant parameters that need to be controlled in order to tailor the memristive properties. 000015616 536__ $$0G:(DE-Juel1)FUEK412$$2G:(DE-HGF)$$aGrundlagen für zukünftige Informationstechnologien$$cP42$$x0 000015616 588__ $$aDataset connected to Web of Science, Pubmed 000015616 650_7 $$2WoSType$$aJ 000015616 7001_ $$0P:(DE-HGF)0$$aRogala, M.$$b1 000015616 7001_ $$0P:(DE-Juel1)125382$$aSpeier, W.$$b2$$uFZJ 000015616 7001_ $$0P:(DE-Juel1)VDB99187$$aKlusek, Z.$$b3$$uFZJ 000015616 7001_ $$0P:(DE-Juel1)VDB17427$$aBesmehn, A.$$b4$$uFZJ 000015616 7001_ $$0P:(DE-Juel1)131022$$aWaser, R.$$b5$$uFZJ 000015616 773__ $$0PERI:(DE-600)1362365-5$$a10.1088/0957-4484/22/25/254001$$gVol. 22, p. 1 - 21$$p1 - 21$$q22<1 - 21$$tNanotechnology$$v22$$x0957-4484$$y2011 000015616 8567_ $$uhttp://dx.doi.org/10.1088/0957-4484/22/25/254001 000015616 909CO $$ooai:juser.fz-juelich.de:15616$$pVDB 000015616 9131_ $$0G:(DE-Juel1)FUEK412$$bSchlüsseltechnologien$$kP42$$lGrundlagen für zukünftige Informationstechnologien (FIT)$$vGrundlagen für zukünftige Informationstechnologien$$x0 000015616 9132_ $$0G:(DE-HGF)POF3-529H$$1G:(DE-HGF)POF3-520$$2G:(DE-HGF)POF3-500$$aDE-HGF$$bKey Technologies$$lFuture Information Technology - Fundamentals, Novel Concepts and Energy Efficiency (FIT)$$vAddenda$$x0 000015616 9141_ $$y2011 000015616 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000015616 9201_ $$0I:(DE-82)080009_20140620$$gJARA$$kJARA-FIT$$lJülich-Aachen Research Alliance - Fundamentals of Future Information Technology$$x1 000015616 9201_ $$0I:(DE-Juel1)PGI-7-20110106$$gPGI$$kPGI-7$$lElektronische Materialien$$x2 000015616 9201_ $$0I:(DE-Juel1)ZCH-20090406$$gZCH$$kZCH$$lZentralabteilung für Chemische Analysen$$x0 000015616 970__ $$aVDB:(DE-Juel1)128701 000015616 980__ $$aVDB 000015616 980__ $$aConvertedRecord 000015616 980__ $$ajournal 000015616 980__ $$aI:(DE-82)080009_20140620 000015616 980__ $$aI:(DE-Juel1)PGI-7-20110106 000015616 980__ $$aI:(DE-Juel1)ZEA-3-20090406 000015616 980__ $$aUNRESTRICTED 000015616 981__ $$aI:(DE-Juel1)PGI-7-20110106 000015616 981__ $$aI:(DE-Juel1)ZEA-3-20090406 000015616 981__ $$aI:(DE-Juel1)VDB881
