Resumen:
The information about porosity in low-· materials obtainable by depth pro¯ling with positron annihilation spectroscopy is reviewed. In particular we focus on Doppler broadening spectroscopy and 2-3 ° ratio of positro- nium measurements on SiOCH and amorphous carbon a-C:F:H thin ¯lms produced by plasma enhanced chemical vapour deposition.
