Abstract

Thermal stability and variations of the electronic properties of amorphous composite film during nanostructuring and the influence of ambient humidity on carbon nanocone growth were studied under an air-operated scanning probe microscopy device. Deviations of the nanocone shape subjected to heat treatments of up to 700degC for 30 min under vacuum conditions was also investigated. A rapid decrease of electroconductivity, an increase of film work function and electric field-induced amorphous-nanocrystalline phase transitions were observed inside the modified regions
