“…A series of admi ttance calculations were made using expression [ 8] for a range of device parameters. These were compared to experimental data in an attempt to determine more about the differential conductance term and the saturation current term .…”

“…curves on the left side of each figure were calculated from expression [ 8 ] and should be compared with the corresponding , more exact curves on the and k~ were simultaneously adjusted to obtain the "best fit"…”
