[Pw_forum] How we can give Temperature to equilibrium system (T=o)

Dear QE users...

i want to know how we can introduce the temperature in our equilibrium
system(i.e after running scf with proper setting of lattice parameter, ecut
and k point, we get ground state total energy(T=0) in scf run).

As i read somewhere that SCF will gives the minimum total energy at T=0,
because in DFT there is no term of temperature.
May be i am wrong but can we introduce temperature  by changing the any
parameter in input file of pw.x.  Actualy i want to generate the  phonon by
the thermal excitation  in my input file by increasing the temperature of
my system or any other means by which i can generate  phonon for
thermo-dynamical  property calculation of the system.

Any type of help will be appreciable .

Thanks and Regards
