“…The peak positions for the principle Bragg reflections are similar to that reported previously for AuNPs synthesized via wet chemical and biological techniques [25][26][27]. The peak at 25° was attributed to the adhesive tape used to affix the sample within the XRD sample stage and is consistent with other data using the same method of XRD sample preparation [28].…”

In this paper, we outline a novel technique for the deposition of nanostructured thin films utilizing a modified form of pulsed laser deposition (PLD). We demonstrate Confined Atmospheric PLD (CAP) for the deposition of gold on cyclic olefin polymer substrates. The deposition process is a simplified form of conventional PLD, with deposition conducted under atmospheric conditions and the substrate and target in close proximity. It was found that this confinement results in the deposition of nanostructured thin films on the substrate. Infrared spectroscopy showed no significant change of polymer surface chemistry as a result of the deposition process, and optical spectroscopy revealed plasmonic behavior of the resulting thin film. The effect of laser fluence on the deposition process was also examined with more uniform films deposited at higher fluences.

“…It can produce high quality epitaxial materials as well as amorphous layers at low temperature. It is also used to produce various nanostructures like nanorods [ 38 , 39 , 40 , 41 , 42 ], nanoparticles [ 41 , 43 , 44 , 45 ], and nanowalls [ 46 ]. A survey [ 26 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 ] of the synthesis parameters of ZnO NWs by PLD is presented in Table 1 presenting the growth parameters such as the type of seed layer, temperature, pressure, and distance between substrate and target.…”

Toward the Growth of Self-Catalyzed ZnO Nanowires Perpendicular to the Surface of Silicon and Glass Substrates, by Pulsed Laser Deposition

Vertically-oriented zinc oxide (ZnO) nanowires were synthesized on glass and silicon substrates by Pulsed Laser Deposition and without the use of a catalyst. An intermediate c-axis oriented nanotextured ZnO seed layer in the form of nanowall network with honey comb structure allows the growth of high quality, self-forming, and vertically-oriented nanowires at relatively low temperature (<400 °C) and under argon atmosphere at high pressure (>5 Torr). Many parameters were shown to affect the growth of the ZnO nanowires such as gas pressure, substrate–target distance, and laser energy. Growth of a c-axis-crystalline array of nanowires growing vertically from the energetically favorable sites on the seed layer is observed. Nucleation occurs due to the matching lattice structure and the polar nature of the ZnO seed layer. Morphological, structural, and optical properties were investigated. X-ray diffraction (XRD) revealed highly c-axis aligned nanowires along the (002) crystal plane. Room temperature photoluminescence (PL) measurements showed a strong and narrow bandwidth of Ultraviolet (UV) emission, which shifts to lower wavelength with the increase of pressure.

“…Investigating the dynamics of interconnected nanorods is essential due to nanotechnology rapid development and its wide applications in different areas such as cable-payload system [18] (space elevator [19], drug delivery [6]), nanomedicine [20], NEMS circuits [21], energy harvesting [11] optical [22] and chemical sensors [23]. Since the interconnection of pH systems via the ports is again a pH system, pH-models will form a powerful tool for analyzing the dynamics and control of interconnected nanorods.…”

Analysis of longitudinal vibration in a nanorod is an important subject in science and engineering due to its vast application in nanotechnology. This paper introduces a port-Hamiltonian formulation for the longitudinal vibrations in a nanorod, which shows that this model is essentially hyperbolic. Furthermore, it investigates the spectral properties of the associated system operator. Standard distributed control and feedback are shown not to be controllable nor stabilizing.
