Title: I-V curve at negative biases in 13.8
Post by: huixiaodemao0712 on August 12, 2014, 15:06

Hi，
I’m calculating the I-V curve of my metal-molecule-metal device using the I-V module in 13.8 version. In the Script window, there is three items: Device, New Calculator and IV curve. Positive and negative bias are calculated separately. For the positive case, I found that the SCF calculation is from 0 V to 2.0 V. However, for the negative case, I set the V1 as -2.0 V and found that the SCF calculation is from -2.0 V to 0 V.

Did I do anything wrong?

Thank you!

Seems like a bug, we'll investigate.

Has it been improved in the 2014.0 version?
