“…In the jet-printing configuration of patterning with FluidFM probes the features patterned were at least three times thicker than the opening diameter The technique outlined is capable of deposition of more complex 3D structures, which can be used further for optical and nanomechanical applications, as unconventional SPM probes and in nanoelectronic devices as interconnects. 1,[55][56][57] Figure 4a shows two freestanding 25 m and 27 m -tall zigzag features (both structures are 500 nm thick). These structures were grown by the deposition of a vertical pillar (3 m in height), followed by the copper electroplating with a laterally translated nanopipette at a rate of 50 nm s -1 , which allowed the construction of a metal wire in a diagonal configuration, with each diagonal inclined at about 60 degrees with respect to the substrate.…”

Nanopipettes are becoming extremely versatile and powerful tools in nanoscience for a wide variety of applications from imaging to nanoscale sensing. Herein, the capabilities of nanopipettes to build complex free-standing three-dimensional (3D) nanostructures are demonstrated using a simple double-barrel nanopipette device. Electrochemical control of ionic fluxes enables highly localized delivery of precursor species from one channel and simultaneous (dynamic and responsive) ion conductance probe-to-substrate distance feedback with the other for reliable high-quality patterning. Nanopipettes with 30-50 nm tip opening dimensions of each channel allowed confinement of ionic fluxes for the fabrication of high aspect ratio copper pillar, zigzag, and Γ-like structures, as well as permitted the subsequent topographical mapping of the patterned features with the same nanopipette probe as used for nanostructure engineering. This approach offers versatility and robustness for high-resolution 3D "printing" (writing) and read-out at the nanoscale.

Atomistic Studies of Nanoindentation—A Review of Recent Advances

This review covers areas where our understanding of the mechanisms underlying nanoindentation has been increased by atomistic studies of the nanoindentation process. While such studies have been performed now for more than 20 years, recent investigations have demonstrated that the peculiar features of nanoplasticity generated during indentation can be analyzed in considerable detail by this technique. Topics covered include: nucleation of dislocations in ideal crystals, effect of surface orientation, effect of crystallography (fcc, bcc, hcp), effect of surface and bulk damage on plasticity, nanocrystalline samples, and multiple (sequential) indentation. In addition we discuss related features, such as the influence of tip geometry on the indentation and the role of adhesive forces, and how pre-existing plasticity affects nanoindentation.

“…The advent of nanoindentation testing has given greater meaning to such probe capability. Emphasis was given previously in [4] to connection with probe aspects of atomic force microscopy for which a new tip fabrication procedure has recently been reported [39]. Another recent application has been to investigate the strain hardening surrounding Figure 6.…”

Crystal Indentation Hardness

Abstract:There is expanded interest in the long-standing subject of the hardness properties of materials. A major part of such interest is due to the advent of nanoindentation hardness testing systems which have made available orders of magnitude increases in load and displacement measuring capabilities achieved in a continuously recorded test procedure. The new results have been smoothly merged with other advances in conventional hardness testing and with parallel developments in improved model descriptions of both elastic contact mechanics and dislocation mechanisms operative in the understanding of crystal plasticity and fracturing behaviors. No crystal is either too soft or too hard to prevent the determination of its elastic, plastic and cracking properties under a suitable probing indenter. A sampling of the wealth of measurements and reported analyses associated with the topic on a wide variety of materials are presented in the current Special Issue.
