Hi,
I have tried looking through the forum but I couldn't find an answer to my question.
I am investigating the difference between a molecular junction with two Au electrodes and a molecular junction with Au and Al.
Doing so I ran into a definition problem of the forward/reverse current and the chemical potential for the Au-Al junction. It seems that in this case the Au (left) is kept at 0 and Al(right) is changed.
A forward bias is defined as VL > VR (that being the voltage of the left electrode is higher than of the right)
in the same line the chemical potential is like this: uL < uR.
When I look at the uL given in the transmission spectra (as I understand is the fermi level of the left electrode) at postive 1V I get that uL = 0 and uR = -1. But this would be uL > uR - so actually reverse bias?
In general I get:
positive 1V: uL=0 , uR = -1
negative 1V: uL=0, uR = +1
I am a little confused here, could you help clarify this for me?
I have attached the note from the tutorial that I tried using to understand this.
Thanks in advance.
