The formation and growth of Palladium Oxide (PdO) onto ultra thin Pd foil by thermal oxidation (TO) is discussed. TO is a flexible method to study the theory of volumetric Pd oxidation, considering the interfaces O2-PdO and PdO-Pd phenomena. The kinetic of the PdO growth on ultra thin Pd foil, clearly shows that oxidation process is governed by a parabolic law, which is directly related to temperature...
Electrical characterization of nanometric PdO films produced by thermal oxidation of Pd films in air at atmospheric pressure is reported. The PdO films were characterized using the van der Pauw-Hall method to establish the effects of oxidation degree of Pd thin films. The measured carrier mobility is directly related to the oxidation rate and film thickness. The produced films are n-type with carrier...
We present a new lateral Schottky-based rectifier called the charge-plasma diode realized on ultrathin silicon-on-insulator. The device utilizes the workfunction difference between two metal contacts, palladium and erbium, and the silicon body. We demonstrate that the proposed device provides a low and constant reverse leakage-current density of about 1 fA/μm with ON/OFF current ratios of around 10...
The functionality of interdigitated gold/aluminum electrodes on PdO films for water vapor (WV) sensing was studied. The characterization of the structure Au/Al/PdO/Al/Au was done at different temperatures introducing WV pulses in the test chamber under a continuous flow of N2 to produce the desired moisture conditions. PdO films were obtained by thermal oxidation of Pd films at 650??C in air atmosphere...
