NON-OHMIC BEHAVIOR IN NEAR-STOICHIOMETRIC RUTILE (TI02)
Abstract
Experimental observations of the isothermal current-voltage relationships in rutile (TiO2) over the temperature range 632 to 908 C have shown that currents in excess of ohmic currents can be drawn through small, single crystals of near-stoichiometric composition. These currents have been identified as space-charge-limited currents, analogous to those observed in the case of a vacuum diode. Increasing the ambient specimen temperature had the effect of displacing the potential for transition from ohmic to nonohmic behavior to greater values so that at 908 C near-stoichiometric rutile exhibited only ohmic currents even at the largest fields employed.
