  1. 6. Design and Modeling of InxGa(1−x)As/InP based Nanosheet Field Effect Transistors for High Frequency Applications

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Hanyu Liu; Xi Chen; [2023]
    Keywords : nanosheet NS ; gate-all-around GAA ; channel release; parasitic channel; MATLAB; COMSOL; technology node; Technology and Engineering;

    Abstract : The advancement of CMOS technology has been fueled by the need to satisfy Moore’s law by shrinking transistors to progressively smaller sizes and increasing the transistor density per unit area [1]. The dimension of the state-of-the-art MOSFET is now down to a few nanometers. READ MORE

  3. 7. Developing an Ar milling process to improve the contact quality to InAs nanowires

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Chris Mkolongo; [2023]
    Keywords : InAs nanowires; Argon milling; Technology and Engineering;

    Abstract : The aim of this work was to develop a stable and reproducible argon milling process for InAs nanowires to remove the native oxide layer that increases electrical resistance. This was done by identifying a few milling parameters and studying them in relation to the milling rate of silicon dioxide (SiO2). READ MORE

  4. 8. In-situ Growth of Sn-seeded GaAs and GaSb Nanowire Heterostructures

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Azemina Kraina; [2023]
    Keywords : nanowire; heterostructure; ETEM; MOCVD; TEM; in-situ; Sn; GaAs; GaSb; materials chemistry; Technology and Engineering; Chemistry;

    Abstract : One of the ways to utilize III-V nanowires, is to make use of the possibility to combine materials and create heterostructures which allows for creating material combinations with new properties. A special interest can be taken into Sb-containing nanowires due to the high electron mobility, however there has been reported difficulties with switching to other materials because of a 'memory effect' where Sb lingers in the system and nanowire.

  5. 9. Mathematical modeling and analysis of hot carrier solar cells

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Benjamin van Dijk; [2023]
    Keywords : solar cell; nanowires; hot carrier; nanowire; analysis; mathematical model; trends; fermi function; reservoirs; Physics and Astronomy;

    Abstract : This thesis focuses on the analysis of a mathematical model of a nanowire based hot carrier solar cell. The relevance of the topic comes from the energy crisis society is facing today. Firstly, we discuss the basic principle of hot carrier solar cells and discuss several energy loss factors. READ MORE

  6. 10. Cold amplification and fiber coupling of a super-conducting nanowire single-photon detector

    University essay from KTH/Tillämpad fysik

    Author : Stéphane Cohen; [2022]
    Keywords : Applied Physics; Tilllämpad fysik;

    Abstract : Single-photon detectors are an essential tool for quantum photonics: one can harness the quantum properties of single photons for quantum communication as well as use the detectors in low illumination applications.Superconducting nanowire single-photon detectors offer high detection efficiency over a widerange of wavelengths, low dark counts, and a good timing resolution compared to single-photonavalanche diodes.
