Oct 1, 2013 · The surface roughness of sputtered Pt deposited by various pressures shows two separate areas: dense (5–40 mTorr) and porous (60–120 mTorr). Additionally, the graph shows a clear tendency of increased roughness with Pt thickness in the thickness range between 50 and 350 nm.

Increasing need and very limited supply of rare Pt is a serious problem in the world. Here, we propose new synthetic way for reducing the use of Pt in a catalytic system by increasing the surface area and modifying the Pt surface structure.

Nov 13, 2019 · We report the structural characterization and nanomechanical properties of platinum (Pt) thin films prepared through facile electrochemical synthesis. The Pt thin films were coated onto indium tin oxide (ITO)/glass substrates by two-electrode electrochemical deposition at room temperature.

Jun 30, 2022 · The Pt-film evolution procedure at 1173 K is shown in (Fig. 3 c) intuitively. Pt atoms arranged in sequence over time, proceeding from the atoms closest to the α-Al 2 O 3 substrate (t = 100 ps) and progressively extending to the upper-layer atoms. The XRD patterns further verified the procedure.
Dec 30, 2021 · Degradation of a metallic film under harsh thermal-mechanical-electrical coupling field conditions determines its service temperature and lifetime. In this work, the self-heating degradation behaviors of Pt thin films above 1000 °C were studied in situ by TEM at the nanoscale.

Dec 8, 2023 · Solid-state thermal dewetting of Pt thin films on SiO2/Si substrates in the ambient of constant flow of H2 or Ar gas was explored for the fabrication of Pt nanoparticles (NPs).
Apr 28, 2022 · In this work, we apply a spin-torque driven ferromagnetic resonance method that is probed in two different ways, optically and electrically, to study the dependence of θ S H in the crystallographic direction in epitaxial Al 2 O 3 /Pt (111), MgO (110)/Pt (110), and MgO (001)/Pt (001) films.
