    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin films; magnetron sputter-deposition; in situ and real-time characterization; early film growth stages; residual stress; manipulation of morphology; Couches minces; pulvérisation magnétron; caractérisation in situ en temps réel; premiers stades de croissance; contraintes résiduelles; manipulation de morphologie;

    Sammanfattning : Vapor-based growth of thin metal films with controlled morphology on weakly-interacting substrates (WIS), including oxides and van der Waals materials, is essential for the fabrication of multifunctional metal contacts in a wide array of optoelectronic devices. Achieving this entails a great challenge, since weak film/substrate interactions yield a pronounced and uncontrolled 3D morphology. LÄS MER

    Sammanfattning : Growth, microstructure and mechanical properties of boron nitride: carbon (BN:C) have been studied in films prepared by reactive r.f. diode sputter deposition as well as by reactive unbalanced d.c. LÄS MER

  5. 4. Reactive Sputtering of Cubic-Phase BN:C and Nanostructured B-N-C Films : Growth, Microstructure, and Mechanical Properties

    Författare :Mats P. Johansson; Ivan Petrov; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Synthesis, structure, and mechanical property related issues in the carbon-containing boron nitride (BN:C) system have been studied. Magnetron sputtering, comprising a B4C target in mixed Ar-N2 discharges and deposition parameters of low ion energy, high ion-to-neutral flux ratio, and substrate temperatures ... LÄS MER

  7. 5. Magnetron Sputter Epitaxy of GaN

    Författare :Muhammad Junaid; Jens Birch; Lars Hultman; Vanya Darakchieva; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Electronic-grade GaN (0001) epilayers have been grown directly on Al2O3 (0001) substrates by reactive DC-magnetron sputter epitaxy (MSE) from a liquid Ga sputtering target in an Ar/N2 atmosphere. The as-grown GaN epitaxial film exhibit low threading dislocation density on the order of ≤ 1010 cm-2 obtained by transmission electron microscopy and modified Williamson-Hall plot. LÄS MER
