  2. 1. Investigation of Novel Metal Gate and High-κ Dielectric Materials for CMOS Technologies

    Author : Jörgen Westlinder; Jörgen Olsson; Stefan Bengtsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; metal gate; high-κ dielectics; titanium nitride; zirconium nitride; MOSFET; thin film; tantalum oxide; aluminum nitride; Elektronik; Electronics; Elektronik;

    Abstract : The demands for faster, smaller, and less expensive electronic equipments are basically the driving forces for improving the speed and increasing the packing density of microelectronic components. Down-scaling of the devices is the principal method to realize these requests. READ MORE

  4. 2. Accident-tolerant uranium nitride

    Author : Aneta Herman; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accident-tolerant fuel; uranium nitride; chromium; glucose; internal sol-gel;

    Abstract : After the nuclear accident at Fukushima-Daiichi in 2011, a search for alternatives to a current fuel-clad standard UO2-Zircaloy was encouraged by government and industry and novel fuel-clad systems were selected. These systems are often referred to as Accident Tolerant systems, because of an improved response to severe accidents. READ MORE

  5. 3. Synthesis of Thin Piezoelectric AlN Films in View of Sensors and Telecom Applications

    Author : Milena De Albuquerque Moreira; Ilia Dr.; Ioshiaki Dr.; Ricardo Cotrin; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminum nitride; reactive sputtering; c-axis oriented films; tilted films; electroacoustic devices; piezoelectric materials; Aluminum Scandium Nitride; HiPIMS; high-k dielectric; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : The requirements of the consumer market on high frequency devices have been more and more demanding over the last decades. Thus, a continuing enhancement of the devices’ performance is required in order to meet these demands. In a macro view, changing the design of the device can result in an improvement of its performance. READ MORE

  6. 4. Defects in Titanium Aluminum Nitride-Based Thin Films

    Author : Janella Salamania; Magnus Odén; Lars Johnson; Lina Rogström; Zoe Barber; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thin films; Ti-Al-N; Defects; Physical vapor deposition;

    Abstract : Coatings and thin films inherently contain several types of defects. This thesis aims to enhance the understanding of the relationship of defects on the growth, structure, stability, and properties of titanium aluminum nitride films synthesized by physical vapor deposition techniques.
