You'll need phonon entropy and electronic entropy as well. Free energy is E-TS. The transition pressure is where the free energy of the two structures are the same. <br><br><div class="gmail_quote">On Sun, Apr 18, 2010 at 5:39 AM, naphtaly moro <span dir="ltr"><<a href="mailto:moronaphtaly84@gmail.com">moronaphtaly84@gmail.com</a>></span> wrote:<br>

<br>
I am working on the pressure induced phase transitions of GaAs, I have<br>
already obtained, the respective EV data for the structures and want<br>
to get the transition pressures for the structures, Any advice on how<br>
this can be done in Espresso?<br>
<br>
Thanks<br>
