The density of the gap states in undoped and phosphorus and antimony doped a-Si:H has been determined from the absorption coefficient measurement. A constant photocurrent method was used to determine the value of optical absorption in the low absorption region. A quantitative model has been suggested to explain all experimental data. The model is based on a Gaussian shaped maximum, connected with the dangling bond, within the exponential band tails just below the middle of the gap. Moderate and strong coping rises the concentration of dangling bonds.
The differential energy albedo has been measured for five different shield materials (aluminium, concrete, iron, tin and lead) for 1250 keV photons obtained from radioactive 60Co, at angular steps of 10°, using a proportional response photon counter. The total energy albedo has been calculated from the measured differential energy albedo by numerical integration. We find that the application of such a counter not only eliminates tedious efficiency corrections needed Air Jordan Shoes For Sale in conventional counting systems, but also improves the accuracy of the measurements.
