We propose a novel and simple method to fabricate aperiodic subwavelength nanostructures by Grayscale Interference Lithography (GIL) with the conventional Lloyd's mirror interferometer and a movable aperture plate.
This paper presents the development and fabrication of first-of-its kind free-standing ferromagnetic shape memory alloy (FSMA)/Si bimorph cantilevers. The exploitation of FSMAs such as Ni-Mn-Ga is of large interest for nanoactuation due to their multifunctional ferromagnetic and shape memory properties allowing for large work density. A new nanofabrication process is developed consisting of electron-beam...
Large-area CuO nanowires have been synthesized by thermal oxidation of porous copper film in static air. The effect of the thermal oxidation temperature and duration are found to influence the growth of CuO nanowires significantly. With an optimized condition, the porous copper film is converted into pure CuO. The application of the as-synthesized CuO nanowires in nanoenergetic materials is also studied...
Two different types of large-area plasmonic nanostructures are fabricated on a silicon wafer and on a glass substrate for surface enhanced fluorescence. Ag coated silicon spikes are formed on a silicon substrate by cryogenic inductively coupled plasma reactive ion etching together with e-beam evaporation, and Ag nanoparticles are embedded in glass by two-step ion exchange. Both of them are demonstrated...
Wafer-scale monolayer graphene film was synthesized on Cu foils by chemical vapor deposition in a 3-in thermal furnace. Graphene film was transferred to the surface of SiO2 (300 nm)/Si substrates using a polymer-assisted method. Hall bar structures were fabricated by lithography and E-beam deposition for the electrical property measurement. Perfect symmetrical ohmic resistance distribution was achieved...
In this paper, a solution method to synthesize well-aligned ZnO nanowires (NWs) arrays on flexible substrates was reported. By investigated the growth of ZnO NWs on Polyimide (PI), it was found that the morphology of ZnO NWs arrays on PI could be controlled by adjusting the parameters. When the thickness of the seed layer is 200nm, the concentration of the zinc nitrate and HTMA is among 5mmol/L and...
Gallium nitride (002) via pulsed laser deposition (PLD) is manufactured on sapphire substrate and hydrothermal-grown ZnO on sapphire. The film was deposited through the 248nm pulsed laser at 5×10− 3 torr nitrogen atmosphere. Temperature was controlled at 800 °C. The morphology of ZnO buffer layer and GaN films was examined using SEM and the crystallinity of the films was examined by XRD. In contrast...
Large-scale synthesis of silver nanowires (AgNWs) is achieved by an improved facile polyol method, with the diameter about 70 nm and the length exceeding 20 µm. The synthesized AgNWs can be processed to form a highly transparent thin film, making nanowire networks to realize high electrical conductivity. Simple oven heating and fast light sintering methods have been examined for curing the films,...
The relaxation properties of three kinds of single layer graphene (SLG) sheets with different aspect ratios on copper substrates are investigated through the molecular dynamics (MD) method. The adaptive intermolecular reactive empirical bond order (AIREBO) potential, the embedded-atom method (EAM) potential and the Lennard-Jones (L-J) potential are utilized to describe the C-C covalent bonds, the...
