• The role of the weakest-link mechanism in controlling the plasticity of micropillars (2009, background): “Norfleet et al. (2008) observed that micropillars having sizes below 5mm evolve a lower-bound dislocation density during deformation that is, on average, in excess of their expected average initial density, with an apparent trend that the average density increases with decreasing microcrystal size.”

• Exploration and Development of High Entropy Alloys for Structural Applications (2014, background): “Micro-sample testing has motivated a great deal of work on this topic, and relationships are being sought for both strength and plasticity [76–78] Additional progress is still needed, especially in defining the size of representative volume elements for particular properties of interest.”
• Review of Nanoindentation Size Effect: Experiments and Atomistic Simulation (2017, background): “[116]), which describes that decreasing the pillar size increases the strength of the weakest deformation mechanism and leads to the increase in the sample strength.”
