<div><P>Hello everyone:</P>
<P> I want to obtain the deformation potential for further calculation of transport properties, but in some</P>
<P>complicated cases(e.g. doped systems), gama and lamda seems not enough for me to induce the value</P>
<P>of deformation potentials. Then I have two questions to ask:</P>
<P> (1) Anyone knows how to extract the deformation potential for certain vibrational mode and certain</P>
<P> electronic state from the "*.vscf" file?<BR><BR> (2)Or if I want to use Frozen Phonon approach after knowning vibrational modes, how could I obtain</P>
<P> the deformation potential from the changes of electronic structure? Does there some formulas</P>
<P> or REFERENCES? </P>
<P>I would like to greatly appreciate any kindly hearted person and any help! </P>
<P> </P>
