  2. 1. Silicon-based Photonic Devices : Design, Fabrication and Characterization

    Author : Ziyang Zhang; Min Qiu; Thomas Koch; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photonic Devices; Silicon Photonics; Parallel Computation; Nanofabrication; Electron Beam Lithography; Optical Characterisation; Optics; Optik;

    Abstract : The field of Information and Communication Technologies is witnessing a development speed unprecedented in history. Moore’s law proves that the processor speed and memory size are roughly doubling each 18 months, which is expected to continue in the next decade. READ MORE

  4. 2. Application of SiGe(C) in high performance MOSFETs and infrared detectors

    Author : Mohammadreza Kolahdouz Esfahani; Henry Radamson; Ya-Hong Xie; KTH; []

    Abstract : Epitaxially grown SiGe(C) materials have a great importance for many device applications. In these applications, (strained or relaxed) SiGe(C) layers are grown either selectively on the active areas, or on the entire wafer. READ MORE

  5. 3. Analysis of Planar and Circular Cylindrical Multilayer Structures with Application to Soft and Hard Surfaces

    Author : Zvonimir Sipus; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antennas; periodic surfaces; integral equations; approximate boundary conditions; soft and hard surfaces; Green s functions; corrugated surfaces; moment method; periodic metal strips; multilayer structures; EFIE; microstrip antennas; spectral domain analysis; group representation theory; strip scatterers;

    Abstract : This thesis deals with the analysis of planar and circular cylindrical multilayer structures, such as strip-loaded dielectric layers, corrugated surfaces and microstrip antennas. In particular, we study corrugations and strip-loaded grounded dielectric slabs when they are used to realize soft and hard surfaces. READ MORE
