Capacitance-Voltage and Current-Voltage Characteristic for Multi-Walled Carbon Nanotubes Grown in Oxygen Atmosphere


Carbon nanotubes were prepared by an arc-discharge method, under different values of pressure of oxygen gas. The structure of multi-walled carbon nanotubes powders has been characterized by low-angle X-ray diffraction .The morphology of carbon nanotube powder was examined by transmission electron microscope. The capacitance-voltage and current- voltage (dark and illumination current) characterization were measured under different values of pressure (10-3, 10-4, 10-5) mbar of oxygen gas.
