Tellurium thin films have been prepared using different rates (0.1 ÷ 30 nm/s) by physical deposition in vacuum on glassy, sintered alumina and electrochemically nanostructured Al2O3 substrates. The sensitivity to nitrogen dioxide of fabricated films

The damping of sensitivity induced by high gas (NO2) concentration in tellurium films was observed for the first time. The phenomenon becomes apparent in ultrathin (less than 40 nm) shown by AFM, SEM and XRD analyses to be in amorphous state. Sensiti

Impedance spectra of tellurium thin films with interdigital platinum electrodes have been measured in dry synthetic air and gaseous media with nitrogen dioxide. Analyses of Cole-Cole plots allowed to evaluate the characteristic frequency, time consta
