Dear GAO,
? Thanks for this input. Please, if you have an electronic copy of any of the
papers, kindly forward it to me. I will be looking ahead for this.
Thanks

For the 1st question( elastic constants' calculations), you can read these
papers (or chanpters of a book):
1-> M.J. Mehl, B.M. Klein, D.A. Papaconstantopoulos, in: J.H. west-Book, R.L.
Fleisher(Eds.), Principles Intermetallic Compounds, vol. 1, Wiley, New York,
1995 (Chapter 9)
2-> M.J. Mehl, J.E., Osburn, D.A. Papaconstantopoulos, B.M. Klein, Phys. Rev. B
41(1990) 10311

Dear all,
I have two questions which? i needed an assistance on how to go about it. I
will be delighted if anybody in the forum can come to my aid.
The first question goes as:
? How can i? calculate the elastic constants(C11,C12 and C44) at (0 K) and (0
GPa) of a semiconductor compound using pwscf ?.
? The second question:
? In studying the phase transition, we need to analysed the enthalpy variation
with pressure. Where the enthalpy(H) = E + PV. So, how can this be implemented
using pwscf?
These are my questions.
