Abstract
Description
Another object of the present invention is to provide designs and assembly of graded-oxide tantalum porous films composed of size-selected nanoparticles.
Anther object of the present invention is to provide dental or biomedical implants that are initially hydrophilic, but becomes hydrophobic soon thereafter.
Primary tantalum nanoparticles were formed by gas-phase condensation inside the aggregation zone 111 (Singh et al. 2013). Atomic metal vapor of
Samples thus manufactured were evaluated in various ways. AFM (
Atomistic mechanisms of nanoparticle coalescence were investigated by MD computer simulation, using the Accelrys (copyrighted) Materials Studio Suite. Using the amorphous cell module, nearly spherical amorphous nanoparticles, 3 nm in diameter, were created, with standard room temperature initial density (i.e. 16.69 g/cm3), and containing 792 tantalum atoms. Each created nanoparticle was geometrically optimized and then equilibrated separately for about 50 ps at all temperatures of interest, namely 100, 300, 1000, and 2300 K, using the GULP parallel, classical MD code (Gale 1997) and the embedded-atom method Finnis-Sinclair potential (Finnis and Sinclair 1984). A number of different configurations were subsequently created, combining 2 or 3 nanoparticles of various sizes, and MD runs were performed on them for a production time of 100 ps, using a time-step of 1-3 fs. Nanoparticles were initially brought close to each other, at a separation distance within the potential cut-off radius. Simulations were run at constant temperature, utilizing a Nose-Hoover thermostat with a 0.1 ps parameter. In all cases, the system presented all interesting behavior and reached a stable configuration within the simulation run time.
After the deposition process, a load-lock mechanism allowed samples to be transferred to an adjacent nitrogen gas filled glove-box for characterization, thus avoiding oxidation or contamination. There, surface coverage and size distribution of the as-deposited nanoparticles were studied by AFM. Fig. 3 is (a) AFM topography image of a sample with low tantalum nanoparticle coverage deposited onto a silicon substrate with (b) height histogram. A Gaussian fit to the histogram is shown in the solid line. The average height is 3.8 nm, in good agreement with the pre-selected size of 3.0 nm by the QMF. The sub-monolayer, low-coverage nature of these samples is evident in the soft tapping-mode AFM image shown in Fig. 3 (b). As deposition occurred at low kinetic energy, nanoparticles retained their original shapes. Bright spots resulted from aggregates of two or more nanoparticles, probably arising from their "piling up" on the surface. The height distribution (Fig. 3 (b)) can be fitted quite well with a Gaussian curve with a peak height (average size) at 3.8 nm. The average size measured by AFM appears is in good agreement with the QMF selected size of 3 nm.
For longer deposition times, continuous layers of tantalum nanoparticles were deposited, first on the surface of the silicon substrate and then on each other. Extended coalescence between nanoparticles led to the formation of a porous thin film. To fully understand the nature of the atomistic mechanisms that govern this coalescence, a number of molecular dynamics computer simulations were run. Previously, coalescence has been extensively studied by means of MD for a number of materials such as gold (Lewis et al. 1997; Arcidiacono et al. 2004), silver (Zhao et al. 2001), copper (Kart et al. 2009; Zhu and Averback 1996), iron (Ding et al. 2004), etc. All studies agree, in general terms, on a common mechanism. By sintering together, nanoparticles reduce their free surface area, creating an interface and thus reducing their overall potential energy. After this primary interaction, necks are formed at the interface, assisted by atomic diffusion. These necks are also considered to be the most chemically active sites, the so-called 3-phase boundaries (Eggersdorfer et al. 2012). Their thickness heavily influences the film properties, which depend on porosity, such as mechanical stability, electrical conductivity, and gas sensitivity.
