(Color online) (a) Top and (b) cross-sectional views of a device with a narrow rectangular pattern made of of thickness , width , and length . Every electrode is connected via metal (made of W) and a buried interconnection line (poly-Si) in insulating . (c) Equivalent circuit consisting of bulky component and interfacial component . The is estimated from the measured voltage and the applied source current . The is estimated from the measured current and the applied source voltage .

(Color online) (a) Resistance response with the application of a pulsed voltage. After the electroforming process, reversible resistance-switching phenomena are shown under application of (“Reset”) and (“Set”) with a duration time of . Insets (I) and (II) show the initial response to the electroforming process and stable resistance-switching behavior, respectively.

(Color online) (a) Raman spectra measured at points (A)–(I), as shown in Fig. 1(a). The spectra were measured at points (X), as shown in Fig. 2. (b) The change in Raman spectrum with application of pulsed voltage. The Raman spectrum was measured at points (E-i), (E-ii), and (E-iii), as shown in Fig. 2. The dashed lines (a visual guide) indicate for and for .
