Evaluating Chromia as a Gate Dielectric and Characterization of Epitaxial Chromia Films
We study electrical conduction in high-quality chromia crystals. A crossover is observed between space-charge limited conduction and the Frenkel-Poole mechanism with increasing temperature, with the crossover occurring in the vicinity of the Neel temperature (308 K) of this material. For thin films, we found the resistance of the sample largely depends on the contact area which they are inversely proportional to each other. Our experiments confirm the excellent dielectric properties of chromia, a result that is important for attempts to utilize this material as a "gate" dielectric in future spintronic devices.
