TLDR
Amorphous carbon films are prepared by pyrolysis of Tetra Chloro Phthalic Anhydride (TCPA) at different temperatures (700 degrees C to 900 degrees C) and DC conductivity measurements are done on the films in the temperature range 300K to 4.2K as discussed by the authors.Abstract:
Amorphous carbon films are prepared by the pyrolysis of Tetra Chloro Phthalic Anhydride (TCPA) at different temperatures (700 degrees C to 900 degrees C). DC Conductivity measurements are done on the films in the temperature range 300K to 4.2K. It shows an activated temperature dependence with a small activation energy (0.02eV to 0.003eV). Variable range hopping is observed at low temperatures. The films are characterised by XRD, SEM, TEM, AFM and microRaman. The electronic structure of the film is used to explain the electrical behaviour.read more

Raman analysis of laser annealed nitrogen doped amorphous carbon film
TL;DR: A micro-Raman spectrometer has been used to study nitrogen doped amorphous hydrogenated carbon (a-C/H(N)) films, which are annealed by a focused argon ion (514.5nm) laser operating at the power density of 300, 750 and 1500 W/mm 2, respectively.
