Calculators

ARPES kz Calculator

Finds the exact photon energy at which photoelectrons have crystal momentum at the Brillouin zone center (Γ) or boundary. Photon momentum is included, so it is also valid for hard X-ray ARPES.

Raman Tensors

Calculates symmetry compositions in polarization-resolved Raman scattering experiments.

UBC Nion Tools

Online calculators and analysis tools for the Nion U-HERMES 200, including EELS references and electron IMFP estimates.
