Wpływ procesu wygrzewania na niektóre właściwości nanorurek węglowych

Carbon nanotubes (CNTs) were synthesized using a chemical vapor deposition (CVD) method. The properties of raw CNTs and after vacuum annealing treatment were studied using electron microscopy (SEM), scanning tunneling microscopy/spectroscopy (STM/STS) and thermogravimetric analysis (TGA) methods. field emission characteristics of the raw and vacuum heated up to 650(st.C) carbon nanotube films (CNTFs) were measured in diode system. Emissive properties of the CNTFs depend on an annaling process during which structural changes in the nanotube walls take place. The structural changes, related to saturation of dangling bonds, influence a rate of oxidation process and also improve the emissive field properties.
