- W2044419702 abstract "In the range 300–1270 K the d.c. conductivity of high-purity arc-fused MgO single crystals was found to be very different during heating and cooling and after room temperature annealing. Measurements with and without guard ring and by the 4-point method gave essentially the same results. Two distinctly different activation energies were found: the 2.5 eV mechanism, already reported in the literature, which is characteristic for high temperatures, > 1000 K, and a 1.1 eV mechanism which progressively builds up in the 700–870 K interval during heating. Between 700–870 K the conductivity rises sharply and cooling yields 1.1 eV-branches which can be cycled many times. Room temperature annealing, however, destroys the 1.1 eV mechanism and leads again to sharply rising conductivity curves in the 700–870 K interval. Remarkable instabilities and occasional short circuiting phenomena were observed during cooling from temperatures slightly above 870 K. In this temperature region the conductivity reacted very fast to a change from Ar to O2. Together with supporting evidence provided by other methods the conductivity behavior appears to be governed by the presence of atomic carbon in the MgO." @default.
