Electron work function in individual multiwalled carbon nanotubes doped with nitrogen and boron
Multi-walled undoped and doped with nitrogen and boron carbon nanotubes have been synthesized by chemical vapor deposition. Based on the analysis of images obtained by electrostatic force microscopy at various tip voltage, the value of the external contact potential difference between the tip a...

| Summary: | Multi-walled undoped and doped with nitrogen and boron
carbon nanotubes have been synthesized by chemical
vapor deposition. Based on the analysis of images obtained
by electrostatic force microscopy at various tip voltage,
the value of the external contact potential difference
between the tip and individual carbon nanotubes is
determined. Using the obtained value of the contact
potential difference, the electron work functions for
undoped and doped with nitrogen and boron individual
carbon nanotubes are calculated, which amounted to 4,7;
4,6 end 5,75 eV, respectively. |
