Characterization of small-scale surface topography using transmission electron microscopy
, 2022 Art.045004, 11 S.Multi-scale surface topography is critical to surface function, yet the very smallest scales of topography are not accessible with conventional measurement techniques. Here we demonstrate two separate approaches for measuring small-scale

Open questions in surface topography measurement: A roadmap
, 2022 Art. 013001, 16 S.Control of surface topography has always been of vital importance for manufacturing and many other engineering and scientific disciplines. However, despite over one hundred years of quantitative surface topography measurement, there are

Surface topography as a material parameter
MRS Bulletin, 2022 AbstractMaterials science is about understanding the relationship between a material’s structure and its properties—in the sphere of mechanical behavior, this includes elastic modulus, yield strength, and other bulk properties. We show in this issue that, analogously, a material’s surface structure governs its surface properties—such as adhesion ...
