Radiation and Thermally Hardened Switching Materials
Abstract
The field switching properties of NbO2/NbO, NbO2/(reduced NbO2) and polycrystalline nonstoichiometric NBO2 have been investigated. Under an applied electric field they switch from a high (greater than 10,000 ohms) to a low (apporximately 10 ohms) resistance in times smaller than 0.7 ns. For pulse durations of several nsec, the current carrying capability is higher than 80 A. the switching mechanism appears to proceed in two stages which could be electrode limited Schottky barrier breakdown and bulk limited field lowering process of NbO2, then followed by a thermal runaway.
