General Questions and Answers / About contact resistance
« on: April 2, 2013, 21:24 »
I used (7,0) CNT with gold electrodes to see the contact resistance. I found out that using different repetitions gave me different result. Can you please tell me why this is happening as the CNT is ballistic and I just changed the number of unit cells (UC) keeping the distance at ends, the same.
I used 5 UC and got ~45k, but when I used 2 UC, I got ~18.2k. Kindly need your help in this regard.
