Hi all,

        I tried to do geometry optimization and dynamics of semiconductor compounds such as InP, GaAs, CdSe, etc. I have tried with all the force field parameters available such as cvff, compass. None of them has all the necessary parameters. Does anyone has suggestions about different forcefields? I am new to forcefield development. I don't know where to start if I want to develop forcefield parameters. Any suggestions will be of great help?

Thanks
