  • Abstract
    A voltage scale, Vs that characterizes electro-thermal runaway, is deduced from the heat conduction equation, Vs = √k/σ´0, where k-is the thermal conductivity and σ´0 is the rate of change of the electrical conductivity with respect to temperature. Vs depends only on material properties and is independent of geometry and the operating voltage. Vs measures the intrinsic tolerance of the material to electro-thermal instability. Numerical values of Vs are consistent with the well-known properties of several common materials.
