  1. 1. Liquid-Phase Exfoliation of Two-Dimensional Materials : Applications, deposition methods and printed electronics on paper

    Författare :Viviane Forsberg; Magnus Norgren; Luis Miguel Pereira Nunes; Mittuniversitetet; []
    Nyckelord :molybdenum disulfide MoS2 ; transition metal dichalcogenide TMD ; thin films; inkjet printing; 2D inks; liquid-phase exfoliation; shear exfoliation; printed electronics; organic electronics; PEDOT:PSS; photoresponse; photocurrent; cathodoluminescence;

    Sammanfattning : After the unprecedented success of graphene research, other materials that can also be exfoliated into thin layers, like Transition metal dichalcogenides (TMDs) such as molybdenum disulfide (MoS2), have also become the subjects of extensive studies. As one of the most promising methods for large scale production of such materials, liquid-phase exfoliation (LPE) has also been the subject of extensive research and is maturing as a field to the point that devices using additive manufacturing and printed nanosheets are often reported.

  3. 2. Photoresponse of Patterned YBa2Cu3O7-x Thin Films

    Författare :Martin Danerud; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The first object of this work was to develop YBa2Cu3O7-x (YBCO) thin films. Initially, Y, BaF2 and Cu were coevaporated with the substrate temperature (TS) 400 °C and the oxygen pressure (pO2) 5 x 10-5 mbar on SrTiO3 substrates with a subsequent high temperature annealing at 890 °C for 15 min in flowing wet oxygen.

  7. 5. Type-II interband quantum dot photodetectors

    Författare :Oscar Gustafsson; Mattias Hammar; Wenquan Ma; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photodetector; quantum dot; infrared; MOVPE; thermal imaging; type-II; photoluminescence; III V; InSb; InGaSb; InAs; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Photon detectors based on single-crystalline materials are of great interest for high performance imaging applications due to their low noise and fast response. The major detector materials for sensing in the long-wavelength infrared (LWIR) band (8-14 µm) are currently HgCdTe (MCT) and AlGaAs/GaAs quantum wells (QW) used in intraband-based quantum-well infrared photodetectors (QWIPs).
