  1. 1. Nanowire Superinductors

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : David Niepce; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Disordered Superconductors; Superinductance; Superinductor; Resonator; Nanowire; TLS;

    Abstract : In this thesis, we demonstrate that a disordered superconductor with a high kinetic inductance can realize a low microwave loss, non-dissipative circuit element with an impedance greater than the quantum resistance (Rq = h/4e^2 = 6.5kΩ). READ MORE

  2. 2. III–V Nanowire Surfaces

    University dissertation from Department of Physics, Lund University

    Author : Martin Hjort; Lund University.; Lunds universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; low energy electron microscopy; scanning tunneling spectroscopy; scanning tunneling microscopy; surface; III–V semiconductor materials; nanowire; photoemission electron microscopy; photoelectron spectroscopy; Fysicumarkivet A:2014:Hjort;

    Abstract : This dissertation deals with the geometric and electronic structure of surfaces on III–V semiconductor nanowires (NWs). NWs made of InAs, GaAs, and InP have been studied using scanning tunneling microscopy/spectroscopy (STM/S), low energy electron microscopy (LEEM), photoemission electron microscopy (PEEM), and x-ray photoelectron spectroscopy (XPS).

  3. 3. Electron Transport in Nanowire Quantum Devices

    University dissertation from Department of Physics, Lund University

    Author : Henrik Nilsson; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Spin-orbit coupling; the Kondo effect; the Zeeman effect; Quantum dots; Nanowire memories; Nanowire transistors; InSb; InAs; Nanowires; Electron transport; Andreev reflections; Nanowire RF-SET; Noise in nanowires;

    Abstract : This thesis focuses on electron transport in semiconductor InAs/InP and InSb nanowire quantum devices. However, first the temperature dependence of classical charge transport in InSb nanowire field-effect transistors, FETs, is characterized, using InAs nanowire FETs as a reference. READ MORE

  4. 4. Vertical III-V Nanowire MOSFETs

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Olli-Pekka Kilpi; Lund University.; Lunds universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanowire; MOSFET; III-V; InGaAs; Vertical; Heterostructure; High frequency;

    Abstract : Vertical III-V nanowire MOSFETs are interesting candidates for future digital and analog applications. High electron velocity III-V materials allow fabrication of low power and high frequency MOSFETs. Vertical vapor-liquid-solid growth enables fabrication of axial and radial heterostructure nanowires.

  5. 5. InAs Nanowire Devices and Circuits

    University dissertation from Electrical and Information Technology, Lund University

    Author : Kristofer Jansson; Lund University.; Lunds universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelling; Circuit; Simulation; Ballistic; Capacitor; Transistor; RF; Band structure; III-V semiconductor; InAs; MOSFET; Metal-oxide-semiconductor field-effect transistor; Nanowire; Amplifier;

    Abstract : Since the introduction of the transistor and the integrated circuit, the semiconductor industry has developed at a remarkable pace. By continuously fabricating smaller and faster transistors, it has been possible to maintain an exponential increase in performance, a phenomenon famously described by Moore’s Law. READ MORE
