AbstractAluminium doped zinc oxide thin films (ZnO:Al) have been deposited on polyester (Mylar type D, 100 μm thickness) substrates at room temperature by r.f. magnetron sputtering. The structural, morphological, optical and electrical properties of the deposited films have been studied. The samples are polycrystalline with a hexagonal wurtzite structure and a strong crystallographic c-axis orientation (002) perpendicular to the substrate surface. The ZnO:Al thin films with 85% transmittance in the visible and infra-red region and a resistivity as low as 3.6×10−2 ωcm have been obtained, as deposited. The obtained results are comparable to those ones obtained on glass substrates, opening a new field of low cost, light weight, small volume, flexible and unbreakable large area optoelectronic devices.

Thin films of near-noble metal silicide such as Pd2Si and PtSi are now being used as rectifying and ohmic contacts in high performance Si devices. These silicides are made by depositing and annealing the metals on Si. The substrate temperature and orientation and the annealing condition can affect the microstructure of the silicide (1) and in turn change the electrical characteristics of the contact.This study attempts to show that detailed structural information about thin Pd2Si films can be obtained from lattice imaging technique. We chose the Pd2Si because it has a hexogonal structure (2) and grows epitaxially on (111) Si with the orientation relationships:(001)Pd2Si // (111)Si and [100]Pd2Si // [110]Si. The epitaxially-grown film will provide a large area or the single crystal Pd2Si for lattice imaging.The Si wafers used were n-type, 10 to 20 Ω-cm, (111) oriented, and HF etched before deposition. The deposition of Pd film of 100Å was carried out by e-beam evaporation at a rate of ∼5Å/sec. in a vacuum of 2x10-7 torr onto room temperature substrates.

Abstract Large-scale growth of two-dimensional (2D) ferromagnetic thin films will provide an ideal platform for studying 2D magnetism and active spintronic devices. However, controllable growth of 2D ferromagnets over large areas faces tremendous challenges. Herein, we report a large-area growth of 2D ferromagnetic single-crystal thin films Cr4Te5 on Al2O3 (0001) substrates using pulsed laser deposition. X-ray diffraction patterns and atomic force microscopy detection confirm that all thin films are high quality epitaxy together with atom-level smooth. Magnetic measurements show the persistence of ferromagnetic ordering state up to above room temperature, with a Curie temperature 320 K, atomic magnetic moment 0.307µB/Cr, and the easy-magnetization axis in film plane. Comparing bulk Cr4Te5 single-crystal, the critical exponent β=0.491 indicates that the magnetic interactions of thin film obey mean-field model rather than 3D Heisenberg model. This work will open a avenue for growing large-scale 2D ferromagnet and developing room temperature 2D magnet-based nanodevices.
