Title: zero bias transmission
Post by: RAJAT on June 15, 2015, 08:04

Dear sir

              what is the use of calculating transmission T(V=0) of devices.
           



           thanks

There are at least two good reasons to calculate the zero-bias transmission spectrum of a device:
1) Zero bias is the starting point for any device operation. If designing a device, you would like to know it's behavior and properties under no applied bias, right?
2) I-V curves require calculating the transmission spectrum for each point along the curve. Such curves will almost always include the V=0 point.
