JunPy is a Python package for spin transport calculation within the framework of non-equilibrium Green’s function method (NEGF). It serves as post analysis tools of first principles calculation under two-probes device to calculate transmission, current, density of states, and spin torque.


  • Transmission
  • Current
  • Density of states
  • Spin torque

Open-source Project

Source codes of JunPy are going to be opened in the future. JunPy is still in development and temporarily unavailable in public.
