Low dimensional materials are those that have at least one dimension small enough for the physical properties of the material lay somewhere between that of individual atoms and the bulk material. The dimensional constraints of nanoparticles, graphene, nanopillars, and nanofibers/tubes result in a large surface area to volume ratio that allows surface states and small structural details to dominate their physical response to mechanical deformation. The importance of in-situ visualization during the test is critical for proper test positioning accuracy as well as the ability to optically correlate sample geometry and real-time deformation behavior to the stress-strain response of the material.
Bruker has developed multiple innovative technologies to accelerate the understanding of low dimensional materials. Combining the strengths of electron microscopy (TEM, SEM) and nanomechanical testing techniques, one can achieve new insights into how to control matter on the nanoscale.
