onsite/hopping
« on: May 5, 2010, 07:41 »
I was searching for  values of onsite and hopping energy of Polyethylene {–(CH2-CH2)n–}, but I cant find it.
Is there anyone around here how helps me? Where or how I could find it.
thanks in advance :)

These parameters are not available in the Quantumwise softare packages now. The more reasonable way is to first perform the DFT calculations and then construct the maximally-localized Wannier function (MLWF). The on-site and hopping parameter of system can be easily obtained from the MLMF. For the details of these steps, you could refer to  the following materials:
