hi,
I want to design the .inp file and .prm file for other material for
example using silver, graphene .. etc. I have following queries:
1. In siliconNitridePsf.tcl; How this is calculated and obtained "set
chargeSi 0.7710 and set chargeN 0, set numBondsSi 4, set numBondsN 3 is
assigned".
2. par_silicon_ions_NEW0.1.inp
how the data is obtained for silicon parameters, I had marked question
mark (?), I really don’t understood how to make them.
--N_2 SI_1 0.100 1.777 !expanding Moorse potential
(Wendel,JCP1992) ???
N_1 SI_2 N_2 0.001 109.47 ! (Wendel,JCP1992)..???

3. Difference between par_silicon_ions_NEW0.1.inp and
par_silicon_ions_NEW5.inp ???
looking forward to get the solutions to my problem
