thanks sir!!
   please tell me getting negative transmission spectrum makes any sense.. or it is totally non-physical and it only means that my script is somewhere wrong..

hello !!!!
          in order to calculate the IV characteristics for a metal_CNT(5nm)_metal using extended huckel, when i find the transmission spectrum b/w (-2,2)ev it shows negative  current for positive voltage.
          then to correct that i increased the range for the transmission spectrum from (-8,16)eV now its giving positive currents... so please tell me is it correct??

General Questions and Answers / Re: Vacuum potential??

« on: July 27, 2012, 13:59 »

Yes you can think it like that, but not exactly. Work function is defined for a single material itself. Here I want to plot graph between Vaccum potential VS distance between the contact formed by any two materials, e.g metal-semiconductor contact. Basically it will give idea about the band diagram formed between the contacts caused by Fermi level alignment.
Any idea??Cause I have seen this in a Journal paper bt din't understand how to calculate it.
