In MOS structure, we should consider non ideal effects when measure the capacitance according to applied voltage. They are 'fixed charge', 'mobile charge', and 'surface states'. When the fixed charge exists in oxide layer, it causes entire curve of graph to shift to the [Fi
surface which was activated by -COOH radicals, and store EDS-spread sample for 1 hour and NHS-spread sample for 2 hours under the low temperature. After all these prodecures, store the chip under the low temperature for 24 hours.
For analysis of the sensing properties, analyze the morphology of the sample with AFM. As analyzing its electrical properties, measure time-variant IV shifting curve fo

surface morphology and roughness of the films was observed by field emission scanning electron microscopy (FE-SEM, Model: JSM-6701F) and atomic force microscopy (AFM, Digital Instrument, nanoscope III) operated at room temperature, respectively. The electrical properties of the films were determined using Hall measurement system (Van der Pauwconfiguration, Hilton, Australia) at room temperature.
Airport management, in common with others involved in the operation of elements of the civil air transportation system, are required to take measures that will provide a high level of protection of buildings and equipment (including aircraft), in addition to ensuring the safety and personal security of passengers and staff using the system. This must be done in manner that disturbs the normal ope
