2.4 Graph shifting
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
measure of the amount of electrical energy stored for a given electric potential. Capacitance is directly proportional to the surface area of the conductor plates and inversely proportional to the separation distance between the plates. If the charges on the plates are +Q and −Q, and V gives the voltage between the plates, then the capacitance is given by
C= Q/V
SI unit of capacitance is
II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
1.2 Structure of Planning for Security
Clearly, the subject of security has wide implications that reach far beyond the jurisdictional limits of the airport to central government itself. Planning to meet the needs of a security emergency requires the involvement of a number of organizations, such as:
∎ The airport administration
∎ The operation airlines
∎ The National
