  2. 1. AlN Thin Film Electroacoustic Devices

    Author : Gonzalo Fuentes Iriarte; I.V. Katardjiev; G.F. Iriarte; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; elektronik; Electronics;

    Abstract : Recently, the enormous growth in personal communications systems (PCS), satellite communication and various other forms of wireless data communication has made analogue frequency control a key issue as the operation frequency increases to the low/medium GHz range. Surface acoustic wave (SAW) and bulk acoustic wave (BAW) electroacoustic devices are widely used today in a variety of applications both in consumer electronics as well as in specialized scientific and military equipment where frequency control is required.

  4. 2. Thin Film Synthesis of Nickel Containing Compounds

    Author : Erik Lindahl; Jan-Otto Carlsson; Jens Birch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemical Vapor Deposition; CVD; Atomic Layer Deposition; ALD; Nickel nitride; Nickel oxide; Nickel; Epitaxy; multilayer; Thin film; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; Oorganisk kemi;

    Abstract : Most electrical, magnetic or optical devices are today based on several, usually extremely thin layers of different materials.  In this thesis chemical synthesis processes have been developed for growth of less stable and metastable layers, and even multilayers, of nickel containing compounds.

  5. 3. Thin films of molecular sieves : synthesis and applications

    Author : Jonas Hedlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : The seed film method for synthesis of ultra thin and thin molecular sieve films was developed. The versatility of the method was demonstrated by successful preparation of films of a number of molecular sieves (silicate-1, ZSM-5, NA) on various supports (silicon, alumina, gold, etc.).

  6. 4. Synthesis and Characterization of Ternary Carbide Thin Films

    Author : Ola Wilhelmsson; Ulf Jansson; Michael Stueber; Uppsala universitet; []
    Keywords : Chemistry; Thin film; dc magnetron sputtering; tribology; carbide; PVD; MAX-phase; DFT; solid solution; Kemi;

    Abstract : This thesis reports on synthesis, microstructure and properties of binary and ternary carbide thin films deposited by dc magnetron sputtering. These materials are interesting since they exhibit a wide range of useful properties, such as high hardness, resistance to wear and oxidation, and high electrical conductivity. READ MORE

  7. 5. Synthesis and Characterization of Amorphous Carbide-based Thin Films

    Author : Matilda Folkenant; Ulf Jansson; Erik Lewin; Paul Mayrhofer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous; coating; thin film; nanocomposite; sputter deposition; PVD; XPS; SEM; TEM; electrical properties; mechanical properties;

    Abstract : In this thesis, research on synthesis, structure and characterization of amorphous carbide-based thin films is presented. Crystalline and nanocomposite carbide films can exhibit properties such as high electrical conductivity, high hardness and low friction and wear. READ MORE
