What is the effect of source/drain dimensions (i.e. area rather than channel's length and width) on characteristics of an OFET?

22 October 2017 1 2K Report

I am more interested in knowing the impact of electrodes dimensions rather than the geometry factor on OFET's characteristics, e.g. ON current.

H M Dipu Kabir

OFET with larger source has higher ON current, current gain and ON-OFF ratio compared to OFET with larger drain.

That happens due to a better injection control.

You can read pages 37-48 of my thesis for more details.
