Quantification of the bond-angle dispersion by Raman spectroscopy and the strain energy of amorphous silicon
P. Roura, J. Farjas, P. Roca i Cabarrocas
A thorough critical analysis of the theoretical relationships between the bond-angle dispersion in a-Si and the width of the transverse optical (TO) Raman peak is presented. It is…
Determination of localized conduction band-tail states distribution in single phase undoped microcrystalline silicon
Sanjay K. Ram, Satyendra Kumar, P. Roca i Cabarrocas
We report on the phototransport properties of microstructurally well characterized plasma deposited highly crystallized microcrystalline silicon films. The steady state photoconduc…
Elucidation of microstructure of single-phase microcrystalline silicon based on crystallite size distributions
Sanjay K. Ram, MD. N. Islam, P. Roca I Cabarrocas +1
Highly crystallized undoped hydrogenated microcrystalline silicon films prepared using SiF4-H2 mixture plasma were investigated at various stages of growth employing different micr…
Influence of fractional composition of crystallite grains on the dark conductivity in fully crystallized undoped microcrystalline silicon
Sanjay K. Ram, Satyendra Kumar, P. Roca i Cabarrocas
Improvement in film growth technology requires a knowledge of the correlation between microstructural and deposition parameters with electrical properties in hydrogenated microcrys…
