A New Approach to the Formation of Nanosized Gold and Beryllium Films by Ion-Beam Sputtering Deposition

Abstract

Thin films of beryllium and gold that are several tens of nanometers thick were obtained, for the first time, on silicon and quartz substrates by the ion-beam method with tenfold alternation of deposition and partial sputtering of the nanosized metal layer. Scanning electron and atomic force microscopy indicate the predominant lateral growth of nanosized metal layers along the substrate surface. Optical spectra indicate the suppression of the localized plasmon resonance. The growth of the film occurs under the influence of the high-energy component of the sputtered metal atoms’ flux. The main role in the formation of the nanosized metal film is played by the processes of the elastic collision of incident metal atoms with the atoms of a substrate and a growing metal film. Metal films that are obtained by the tenfold application of the deposition–sputtering of a nanoscale metal layer are characterized by stronger adhesion to the substrate and have better morphological, electrical, and optical characteristics than those that are obtained by means of direct single deposition.

Interface Engineering Enables High-Performance Sb Anode for Sodium Storage

“…Nevertheless, the key problem obstructing the practical application of Sb anodes is due to its poor cyclability, which can be ascribed to the dramatic volume expansion during repeated sodiation, further bringing about the pulverization of the electrode and loss of electrical contact between Sb and the current collector [ 8 , 9 , 10 , 11 ]. The dimensional structure of matter has a great influence on its related properties [ 12 , 13 , 14 , 15 ]; hence, it is very important to develop feasible methods to alleviate the volume expansion during charging and discharging processes, and improve the mechanical properties of Sb for the practical application of Sb anodes.…”

Magnetic Properties and Microstructure of FePt(BN, X, C) (X = Ag, Re) Films

“…The Ag was used to enhance the FePt ordering via diffusion of Ag, which induces atom replacement through vacancies [ 5 , 6 , 9 , 19 , 20 ]. To study the FePt-X composite films, interface chemistry in heterostructures [ 21 ] and other functional alloy, oxide and composite films prepared in sputtering [ 22 , 23 ] and other thin-film formation technologies [ 24 , 25 ] was also addressed.…”

Continuous Patterning of Silver Nanowire-Polyvinylpyrrolidone Composite Transparent Conductive Film by a Roll-to-Roll Selective Calendering Process

“…The flexibility must be approached from the complex viewpoint of materials and manufacturing processes, including miniaturization, lightweight, efficiency, and yield. While the thin film structures of metals and composites has conventionally been manufactured using electrochemical deposition [ 4 , 5 , 6 ] and ion-beam sputtering [ 7 ] as the batch type, the roll-to-roll (R2R) process has endowed electronic devices with more flexibility and mass-producibility. Silver nanowires (Ag NWs) are still receiving great attention as flexible electronic materials, even though many reports with a variety of manufacturing technologies have been published over a long period of time.…”
