Band edge discontinuities and carrier transport in c-Si/porous silicon heterojunctions
Md. N. Islam, Sanjay K. Ram, Satyendra Kumar
We have prepared light emitting nanocrystalline porous silicon (PS) layers by electrochemical anodization of crystalline silicon (c-Si) wafer and characterized the c-Si/PS heteroju…
Fractional composition of large crystallite grains: a unique microstructural parameter to explain conduction behavior in single phase undoped microcrystalline silicon
Sanjay K. Ram, Satyendra Kumar, P. Roca i Cabarrocas
We have studied the dark conductivity of a broad microstructural range of plasma deposited single phase undoped microcrystalline silicon films in a wide temperature range (15 - 450…
Normal and anti Meyer-Neldel rule in conductivity of highly crystallized undoped microcrystalline silicon films
Sanjay K. Ram, Satyendra Kumar, P. Roca i Cabarrocas
We have studied the electrical conductivity behavior of highly crystallized undoped hydrogenated microcrystalline silicon films having different microstructures. The dark conductiv…
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…
Structural Determination of Nanocrystalline Si Films Using Ellipsometry and Raman Spectroscopy
Sanjay K. Ram, Md. N. Islam, P. Roca i Cabarrocas +1
Single phase nano and micro crystalline silicon films deposited using SiF4/H2 plasma at different H2 dilution levels were studied at initial and terminal stages of film growth with…
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…
