      abstract     = {In this study, we have investigated the indentation size
                      effect (ISE) of single crystalline tungsten with low defect
                      density. As expected, the hardness shows a pronounced
                      increase with decreasing indentation depth as well as a
                      strong strain rate dependence. For penetration depths
                      greater than about 300 nm, the ISE is well captured by the
                      Nix–Gao model in the context of geometrically necessary
                      dislocations. However, clear deviations from the model are
                      observed in the low depth regime resulting in a bilinear
                      effect. The hardness behavior in the low depth regime can be
                      modeled assuming a non-uniform spacing of the geometrically
                      necessary dislocations. We propose that the bilinear
                      indentation size effect observed reflects the evolution of
                      the geometrically necessary dislocation density. With
                      increasing strain rate, the bilinear effect becomes less
                      pronounced. This observation can be rationalized by the
                      activation of different slip systems.},
