Abstract
This paper deals with the structure, composition and electro-optical c haracteristics of n-type amorphous and microcrystalline silicon thin f ilms produced by plasma-enhanced chemical vapour deposition in a hydro gen-helium mixture. In addition, special emphasis is given to the role that hydrogen incorporation plays in the film's properties and in the characteristics of n-type microcrystalline films presenting simultane ously optical gaps of about 2.3 eV (controlled by the hydrogen content in the film), a dark conductivity of 6.5 S cm(-1) and a Hall mobility of about 0.86 cm(2) V-1 s(-1), the highest combined values for n-type microcrystalline silicon films, as far as we know.
