  1. 1. Generation and detection of entangled single-photon pairs

    Kandidat-uppsats, Uppsala universitet/FREIA

    Författare :Gabriella Tesfamichael Habtezion; [2024]
    Nyckelord :;

    Sammanfattning : Quantum information technology is an emerging field with important applications such as quantum cryptography and teleportation, quantum imaging and lithography. These applications make use of single photons and pairs of entangled photons. In this work, we experimentally generate and attempt to detect the entangled photons. LÄS MER

  3. 2. Design and implementation of a signaling system for a novel light-baseed bioprinter : Design och implementering av ett signalsystem för en ny ljusbaserad bioprinter

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Sammanfattning : A 3D bioprinter employing light-based technology has been designed and constructed in an EU-funded research initiative known as BRIGHTER (Bioprinting by Light-Sheet Lithography). This initiative is a collaborative effort between institutions and companies and aims to develop a technique for efficient and accurate production of engineered tissue. LÄS MER

  4. 3. Grafik som folkbildning : En analys av litografins spridning i det svenska folkhemmet 1947-1957

    Master-uppsats, Södertörns högskola/Institutionen för kultur och lärande

    Författare :Catarina Drugge; [2023]
    Nyckelord :Graphics; Graphic Art; litography; democracy; public education; Pierre Bourdieu; sociology; public home; Konstfrämjandet; Grafik; litografi; folkbildning; Pierre Bourdieu; folkhemmet; kulturpolitik; konstföreningar; Konstfrämjandet;

    Sammanfattning : Graphic Art as Public Education – a Study of the Spreading of Litographic Prints in Swedish Homes 1947-1957  This thesis aims to analyze how graphics as an art form became a tool to democratize art during the period of 1947–1957 in Sweden. Graphic art refers to the collective term that includes multiplied art prints: lithography, etching, woodcut, and serigraphy. LÄS MER

  5. 4. Fabrication and Characterization of Quantum-well Field Effect Transistor

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Yang Fu; [2022]
    Nyckelord :quantum-well field-effect transistor; InGaAs; subthreshold swing; sheet resistance; contact resistance; electron mobility; Post Metallization Annealing; electrostatic control; Physics and Astronomy;

    Sammanfattning : The project aims to optimize the design and fabrication of InGaAs quantum-well field-effect transistor (QW-FET) by investigating transfer and output characteristics of the QW-FET. This work found a lower source/drain contact resistance solution starting with fabricating micrometer-level gate length transistors. LÄS MER

  7. 5. BCP Lithography Defined Arrays of InAs NWs Grown Using MOVPE with Au Seeds

    Master-uppsats, Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/Fasta tillståndets fysik

    Författare :Björn Landeke-Wilsmark; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this report we outline a detailed process flow for a quick and inexpensive implementation of large dense arrays of InAs nanowires (NWs) grown in the reactive ion etching/etched (RIE) pores of a SiO2/SiNx mask on top of an InAs/Si(111) substrate. The self-assembled (hexagonally close-packed) pattern of poly(methyl-methacrylate) (PMMA) cylinders in a poly(styrene) (PS) matrix adopted by a linear diblock poly(styrene-block-methyl-methacrylate) P(S-b-MMA) block-copolymer (BCP) was transferred to the dielectric stack (consisting of a ≈10 nm plasma enhanced chemical vapour deposition/deposited (PECVD) SiNX layer topped by a thin atomic layer deposition/deposited (ALD) SiO2 film) using a two-step RIE procedure.
