Abstract
A thermometer based on CB tunnelling includes a sensor component and devices for measuring its voltage-current dependence. The sensor includes a chain of several, at least ten, nanoscale tunnel junctions and connection electrodes for connecting the measurement devices to the ends of the chain. The temperature is determined in a manner that is, as such, known, on the basis of the characteristic quantities of the descriptor G/G.sub.T of the voltage-current dependence. The measurement array of the sensor includes several tunnel junction chains connected in parallel, for decreasing the total impedance of the array.
