The effect of aging on the dark conductivity and noise in hydrogenated microcrystalline silicon thin films
Güneş, Mehmet; Johanson, R. E.; Kasap, S. O.; Finger, F.; Lambertz, A. (Wiley-V C H Verlag Gmbh, 2010)Aging hydrogenated microcrystalline silicon in air is found to affect both the dark conductivity and the 1/f noise. For a sample with a crystalline volume fraction of 0.39, the conductivity decreased by three orders of ... -
The effects of air, oxygen and water exposure on the sub-bandgap absorption, the electronic conductivity and the ambipolar diffusion length in highly crystalline microcrystalline silicon films for photovoltaic applications
Güneş, Mehmet; Smirnov, V.; Finger, F.; Brueggemann, R. (Springer, 2020)Reversible and irreversible changes due to long term air and short term de-ionized water (DIW) or pure oxygen exposure were investigated in about 1 mu m thick hydrogenated microcrystalline silicon (mu c-Si:H) films deposited ... -
The effects of native and light induced defects on optoelectronic properties of hydrogenated amorphous silicon-germanium (a-SiGe:H) alloy thin films
Güneş, Mehmet; Yavas, M. E. D.; Klomfass, J.; Finger, F. (Springer, 2010)Effects of native and light induced defects states in hydrogenated amorphous silicon-germanium alloy thin films with different Ge concentrations have been investigated by using steady-state photoconductivity, dual beam ... -
Instability effects in hydrogenated microcrystalline silicon thin films
Yilmaz, G.; Turan, E.; Gunes, M.; Smirnov, V.; Finger, F.; Brueggemann, R. (Wiley-V C H Verlag Gmbh, 2010)Instability effects on the dark conductivity (sigma(Dark)) and photoconductivity (sigma(photo)) of microcrystalline silicon films with different microstructures deposited on smooth and rough substrates, after exposure to ...
