Abstract

Many theoretical and experimental stuidies have been reported (1,2) on the metal-insulator-metal (MIM) point contact diode as a device to measure infrared optical frequencies. Electron tunnelling is the most widely accepted explanation for the extremely broadband response of MIM diodes. However, there is evidence for at least one more phenomenon, slower and possibly of thermal origin, occurring in the diode (3); this effect could be responsible of a masking effect particularly important near visible frequencies (2), where the absorption of the metals becomes greater, and tentatively contributes tc opposite polarity video detection at visible wavelengths (4). Purpose of the present work was to perform a systematic investigation on a W-Ni MIM point contact diode at different IR and FIR wavelengths. Results will be discussed which yield the determination of a cutoff for the slow mechanism and clearly demonstrate the suggested thermal origin of the effect.
