Popis: | Early microwave detectors consisted of loose metal-metal contact of which at least one metal-surface was automatically oxidised under ordinary atmospheric conditions. Metal-excess oxides behave as n-type semiconductors and metal-deficient or oxygen excess oxides behave as p-type ones. In one of the typical microwave sensors a rather thick ZnO film was electrochemically deposited on mother Zn. Later a mechanically pressed point-metallic contact was made on it. Nonlinear I-V characteristics were obtained showing rectification properties. Some complex mixed metal oxides behave as warm superconductors. |
