High Field Conduction and Switching Phenomena and Magnetic Spin Resonance in Metal Oxide Thin Films and Surfaces.

摘要

Investigation was performed on transport, dielectric, switching and optical properties of thin amorphous and polycrystalline films of a series of transition metal and other oxides films. The conduction and dielectric dispersion mechanisms were unambigously identified for each oxide studied in the parent metal-oxide-parent metal configuration. The switching phenomena and the observed RF oscillations in the negative resistance region were fully explained by the double injection model. Stable and reproducible switching devices were fabricated and the properties of important switching parameters studied as a function of composition temperature and applied voltage. (Author)
