Performance of EH Hamiltonian

Performance of EH Hamiltonian

Problem/Objective:

  • Benchmark EH against another TB strain solver to determine the performance of the band structure calculation in EH.

Approach:

  • A 7x7x7 silicon super cell was used to perform a Schrodinger simulation for TB and EH.
  • The simulation was computed on a single k-point under a hydrostatic strain.

Results:

  • EH implementation is as fast as TB even though it has a larger interaction radius (1nm).
  • The simulation was computed on a single k-point under a hydrostatic strain.
