ABSTRACTSilicon oxycarbide microcrystalline layers, n- and p-doped, highly conductive and highly transparent have been produced using a Two Consecutive Decomposition and Deposition Chamber (TCDDC) system. The films exhibit suitable properties for optoelectronic applications where wide band gap materials with required conductivity and stability are needed. In this paper we present the role of partial oxygen pressure (po2) in controlling the composition, structure and transport properties (conductivity, σd and optical gap, Eop) of silicon oxycarbide microcrystalline layers.

AbstractWide band gap microcrystalline silicon films have aroused considerable interest since they combine some electro-optical advantages of amorphous and crystalline materials highly important to produce electro-optical devices such as TFTs and solar cells. In this paper we present results concerning the electro-optical characteristics of highly transparent and conductive n-type µc-Si based films. Here, emphasis is given to the production of n-type ýtc-films with optical gaps of 2.3 eV and dark conductivity's of 6.5 Scm-1
