This work presents and combines the alternative concepts of resistively switching devices, usable as nonvolatile memory elements or switches, and nano crossbar architecture, which defer these physical limits sustainably. The nano crossbar architecture consists of a functional component that is integrated between two perpendicularly crossing metallization lines. This configuration allows for a high integration density due to a minimal footprint of 4 F$^{2}$ (F = minimum Feature size). The basic elements are straight metallization lines with excellent scaling capability and fabricated by competitive technologies such as nano imprint lithography. The functional component can be composed of reversibly switching TiO$_{2}$, which is integrated into metal/ insulator/ metal elements (MIM). This can be operated by corresponding set- and reset- voltages between at least two resistance states, which represent a logic "0" or "1". The state is nonvolatile and can be nondestructively determined by voltages below these programming values. The field of application includes memory matrices, which are also named passive ReRAM (Resistive Random Access Memory), elements of the DRL (Diode-Resistor Logic) and RTL (Resistor-Transistor Logic), as well as router and multiplexer. Because of their passive properties, an active control circuitry, which is currently based upon CMOS, is necessary. For this reason, all materials and fabrication technologies are CMOS compatible. The developed and optimized lift-off metallization in combination with electron beam direct writing is a flexible method to fabricate metallization lines with different metals and with a width of 50 nm. The fabricated devices comprise crossbar arrays with a size of 64 × 64 bit and a 30 nm thermally evaporated electrode of a Pt/ Ti double layer. These were examined in terms of ballistic charge transfer mechanisms, since the dimensions of the conductor were in the range of the electron mean free path. The experimental results could be explained by the models of Fuchs-Sondheimer and Mayadas-Shatzkes. Finally, the metal lines offered a high yield and a good scalability with low resistances per unit length. The TiO$_{2}$ thin film was reactively sputtered or deposited by ALD (Atomic Layer Deposition). Subsequently, the electrical transfer from the insulating to the switching state, also called electroforming, was examined in detail and allowed for a reliable bipolar switching. The required operating voltages and currents of 100 · 100 nm$^{2}$ large cells are 2 V and several 100 $\mu$A, [...] 000136215 650_4 $$aRRAM (Resistive Random Access Memory) 000136215 650_4 $$aresistive switching 000136215 650_4 $$asemiconductor device 000136215 650_4 $$alithography 000136215 650_4 $$ananostructures 000136215 8564_ $$uhttps://juser.fz-juelich.de/record/136215/files/Information_10.pdf$$yOpenAccess 000136215 8564_ $$uhttps://juser.fz-juelich.de/record/136215/files/Information_10.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000136215 8564_ $$uhttps://juser.fz-juelich.de/record/136215/files/Information_10.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000136215 8564_ $$uhttps://juser.fz-juelich.de/record/136215/files/Information_10.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000136215 909CO $$ooai:juser.fz-juelich.de:136215$$pdnbdelivery$$pVDB$$pdriver$$popen_access$$popenaire 000136215 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000136215 9141_ $$y2013 000136215 920__ $$lyes 000136215 9201_ $$0I:(DE-Juel1)ZB-20090406$$kZB$$lZentralbibliothek$$x0 000136215 9201_ $$0I:(DE-Juel1)VDB782$$kIFF-2$$lTheorie der Weichen Materie und Biophysik$$x1 000136215 970__ $$a2128/3772 000136215 9801_ $$aFullTexts 000136215 980__ $$aI:(DE-Juel1)ICS-2-20110106 000136215 980__ $$aUNRESTRICTED 000136215 980__ $$aJUWEL 000136215 980__ $$aConvertedRecord 000136215 980__ $$aVDB 000136215 980__ $$abook 000136215 980__ $$aFullTexts 000136215 981__ $$aI:(DE-Juel1)IBI-5-20200312 000136215 981__ $$aI:(DE-Juel1)IAS-2-20090406 000136215 981__ $$aI:(DE-Juel1)ICS-2-20110106
