  2. 1. Electrical properties of polycrystalline silicon

    Author : Matts Rydberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Elektronik; Electronics;

    Abstract : Polysilicon is used, among other materials, in today's integrated circuits. In this thesis, the structural and electrical properties' of polysilicon thin film resistors have been studied. The aim has been to improve the long-term stability and increase the knowledge concerning grain-boundary related phenomena. READ MORE

  4. 2. A single trapped Rydberg ion

    Author : Gerard Higgins; Markus Hennrich; Tilman Pfau; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Trapped ions; Rydberg physics; quantum information platforms; atomic physics; fysik; Physics;

    Abstract : Systems of trapped ions and systems of ultracold Rydberg atoms are used at the forefront of quantum physics research and they make strong contenders as platforms for quantum technologies. Trapped Rydberg ions are a new hybrid technology envisaged to have both the exquisite control of trapped ion systems and the strong interactions of Rydberg atoms. READ MORE

  5. 3. Fast and Scalable Entangling Gate in Trapped Ions via Rydberg Interaction

    Author : Chi Zhang; Markus Hennrich; Peter Zoller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; trapped ions; Rydberg interaction; quantum entanglement; fysik; Physics;

    Abstract : Trapped Rydberg ions are a novel platform for quantum information processing. This approach combines the advanced quantum control of trapped ions and the strong dipolar interaction of Rydberg atoms. READ MORE

  6. 4. Time-resolved laser spectroscopic studies of atoms, ions and Molecules

    Author : Zhongshan Li; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:2000:Li;

    Abstract : Time-resolved laser spectroscopy has been performed to study the radiative properties of various microscopic systems. Using Laser-Induced Fluorescence (LIF) techniques, natural radiative lifetimes have been studied not only in neutral B, S, Ge, Ce, Pb, and in singly ionized V, Fe, Zr, Mo, La, Ce, Eu, Gd and Yb, but also in doubly ionized La, Ce, Pr, Eu, Er, Gd, Tm, Lu, and W.

  7. 5. Time Resolved Laser Spectroscopy of Rydberg States in Group IIIA and IIIA Elements

    Author : Göran Jönsson; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this work radiative properties of neutral elements with one or two electrons outside closed subshells have been investigated. Using laser techniques in connection with atomic beams selective excitation of Rydberg states was performed. Most of the studied states were populated with two-step excitation. READ MORE
