A finite difference scheme for integrating the Takagi-Taupin equations on an arbitrary orthogonal grid

Mads Carlsen, Hugh Simons

Calculating dynamical diffraction patterns for X-ray topography and similar x-ray scattering-imaging techniques require the numerical integration of the Takagi-Taupin equations. Th…

Unveiling the interaction mechanisms of electron and X-ray radiation with halide perovskite semiconductors using scanning nano-probe diffraction

Jordi Ferrer Orri, Tiarnan A. S. Doherty, Duncan Johnstone +5

The interaction of high-energy electrons and X-ray photons with soft semiconductors such as halide perovskites is essential for the characterisation and understanding of these opto…
