It is an equality of voltage drop U across p-n junction to thermal voltage kT/q. Use of this criterion has allowed to express a value of maximal measurable temperature T* through physical and design parameters of diode and an excitation current. It is shown that variation of diode parameters giving rise to extension of the range of temperatures measurable by means of diode sensor is accompanied by reducing of its sensitivity. As an example validity of determined theoretically relation between T* and silicon temperature sensor parameters has been experimentally verified.","PeriodicalId":378441,"journal":{"name":"ASDAM '98.

The extraction of parameters from the measured I-V characteristics based on the classical thermionic emission-diffusion theory usually fails, especially at lower temperatures. We present a new more complex physical model which includes also the effects of surface generation-recombination and tunneling of free carriers via surface deep traps. Then the correlation of simulation experimental I-V characteristic is obtained in a much wider range of applied voltages and temperatures.","PeriodicalId":378441,"journal":{"name":"ASDAM '98.
