“…To measure the deposition rate, a small piece of silicon with an ink mark was located in the substrate holder and 457 pulses were shot. After the deposition, the ink was removed and the step was measured by atomic force microscopy (AFM) [12].…”

“…The vacuum arc plasma formation technique used by us has been fully described elsewhere. 24 Briefly, a repetitively pulsed vacuum arc plasma gun equipped with a gold cathode was used to form a dense gold plasma, which was then transported through a 90°b ent solenoidal magnetic filter to remove any solid particulates ͑cathode debris, also called "macroparticles"͒ from the plasma stream. For the work described here the plasma pulses were 5 ms long and the repetition rate was 1 pulse/s.…”

Phys. PMMA ͑polymethylmethacrylate͒ was ion implanted with gold at very low energy and over a range of different doses using a filtered cathodic arc metal plasma system. A nanometer scale conducting layer was formed, fully buried below the polymer surface at low implantation dose, and evolving to include a gold surface layer as the dose was increased. Depth profiles of the implanted material were calculated using the Dynamic TRIM computer simulation program. The electrical conductivity of the gold-implanted PMMA was measured in situ as a function of dose. Samples formed at a number of different doses were subsequently characterized by Rutherford backscattering spectrometry, and test patterns were formed on the polymer by electron beam lithography. Lithographic patterns were imaged by atomic force microscopy and demonstrated that the contrast properties of the lithography were well maintained in the surface-modified PMMA.

“…11,12 From Fig. 3(b), it can be seen that with the increasing diameter of the nanowire, the Young's modulus decreases in the examined range and approaches a value about 160 GPa, which is comparearble with 168 GPa of bulk Pt 27,28 and 120 GPa of the carbon pillar fabricated by FIB. 13 This is similar to the trends previously reported.…”

Platinum (Pt) composite nanowires were grown on the tip of tungsten (W) microprobes by focused-electron-beam induced chemical vapor deposition (FEB-CVD). An electrical field was used to drive a transversal mechanical vibration of the nanowires. Such nanowire vibrations were found to display the first and second harmonic resonances with frequencies in the range of tens of MHz. The Young's modulus of the nanowires was estimated to be in the range of (1.4 ± 0.1) × 102 GPa to (4.7 ± 0.2) × 102 GPa, dependent on the wire size. A mass responsivity of 2.1 × 1021 Hz/kg was demonstrated with the minimum detectable mass of about 0.4 attogram. Our results indicated the potentials of FEB-CVD for the fabrication of nano-balances on any surface for ultra-sensitive mechanical applications.
