  2. 6. Integration of Two-Dimensional Materials for Electronics and Photonics

    Author : Arne Quellmalz; Kristinn Gylfason; Frank Niklaus; Cedric Huyghebaert; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Two-dimensional (2D) materials with a thickness on the atomic scale promise to continue the trend of increasing performance in electronics, photonics, and sensing. However, despite record-breaking demonstrations of individual devices, the commercial exploitation of 2D materials is still limited. READ MORE

  4. 7. 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.

    Abstract : During the last two decades, increase in electricity demand and environmental concern resulted in fast growth of power production from renewable sources. Wind power is one of the most efficient alternatives. READ MORE

  6. 9. Fabrication Technology for Efficient High Power Silicon Carbide Bipolar Junction Transistors

    Author : Reza Ghandi; Martin Domeij; Anant Agarwal; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Other engineering physics; Övrig teknisk fysik;

    Abstract : The superior characteristics of Silicon Carbide as a wide band gap semiconductor have motivated many industrial and non-industrial research groups to consider SiC for the next generations of high power semiconductor devices. The SiC Bipolar Junction Transistor (BJT) is one candidate for high power applications due to its low on-state power loss and fast switching capability. READ MORE

  7. 10. Demand responsive resource management for cellular networks : link asymmetry, pricing and multihopping

    Author : Magnus Lindström; Jens Zander; Narayan Mandayam; KTH; []
