pySED

To implement the phonon SED (spectral energy desity) method in 2010, phonon lifetime can be calculated.

Main features

  • Output SED image
  • Using Lorentz to fitting the SED peak
  • Fit all peaks at once and output phonon lifetimes, or can fit them individually
  • Simple and easy to use
  • Phonon lifetime can only be obtained qualitatively

Installation instructions

  1. From source code
# python setup.py install --user --prefix=

For convenience, you may want to copy (or link) the files inside scripts folder to a location included in $PATH environment variable

Usage

Here three example are provided to show how to use pySED. If one can reproduce the case in the example, one should use the program.

If I have the time, I might provide a detailed tutorial manual.
