Step- and terrace-resolved crystal truncation rod scattering from vicinal surfaces under coherent heteroepitaxy

This paper develops a unified theoretical framework for crystal truncation rod (CTR) scattering from vicinal surfaces under coherent heteroepitaxy, demonstrating that non-specular rods can sensitively probe full elastic distortions, such as shear-induced triclinic deformation, while maintaining the ability to resolve step- and terrace-level structural and kinetic information during growth.

Bottom-up realization of a type-II organic-TMD heterointerface: Pentacene on monolayer WS2

Using molecular beam epitaxy and advanced spectroscopic techniques, the researchers demonstrate the bottom-up synthesis of a highly ordered pentacene/monolayer WS2\text{WS}_2 heterostructure that exhibits a type-II band alignment, establishing it as a model system for studying charge transfer in hybrid organic-inorganic interfaces.
