ALT EDITORS' SUGGESTION Structure analysis of PTCDA/Ag(100) by low-energy electron diffraction and density functional theory 23 February, 2026 This is one of the most challenging surface structures solved by the LEED-IV method so far, because the data set is limited and the molecules consist of a large number of atoms. Nevertheless, by usingsymmetry-restrictions and DFT support, the authors can identify significant corrugations of both the molecules and the underlying silver surface. This verifies the structural response to the chemical interactions across the interface on both the molecule and the metal surface. Ina Krieger et al. Phys. Rev. B 113, 075425 (2026)

ALT EDITORS' SUGGESTION Elastic plate basis for the deformation and electron diffraction of twisted bilayer graphene on a substrate The authors derive here a basis from elastic plate theory to quantify equilibrium and dynamic deformation in twisted bilayer graphene (TBG). The formulation captures the relaxed structure of freestanding and substrate-supported TBGs using a small number of basis terms. The results are validated against atomistic simulations and electron diffraction experiments. TBG dynamics are further explored through phonon band structure analysis, linking low-energy phonons to simple elastic plate models. Moon-ki Choi, Suk Hyun Sung, Robert Hovden, and Ellad B.
