  1. 36. Development of novel materials for solar cells

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Klara Takei; [2015]
    Keywords : Sputter target; CIGSe; chalcopyrite; compound; mechanical alloying; milling; hot pressing;

    Abstract : More efficient and cheaper solar cells are necessary if photovoltaics are to play a major rolein the field of sustainable power generation. Copper indium gallium selenide (CIGSe) is one of the best suited materials for thin film solar cell absorbers. READ MORE

  3. 37. The application of resistivity and IP-measurements as investigation tools at contaminated sites : a case study from Kv. Renen 13, Varberg, SW Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Sofia Åkesson; [2015]
    Keywords : geophysics; resistivity; induced polarization; contaminated site; hydrogeology; trichloroethene; TCE; Earth and Environmental Sciences;

    Abstract : An old industry estate, Kv. Renen 13, is located in central Varberg, southwest Sweden, and is known from previous investigations as highly polluted. READ MORE

  4. 38. A 2D Electrical Resistivity Survey of Palsas in Tavvavuoma, sub-arctic Sweden

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Per Marklund; [2014]
    Keywords : Palsas; permafrost; peat plateaus; resistivity; ert; geophysics; Tavvavuoma; Palsar; permafrost; torvplatåer; resistivitet; ert; geofysik; Tavvavuoma;

    Abstract : Electrical resistivity tomography (ERT) is a commonly used geophysical method to investigate permafrost in the mountain environment, but few studies have employed this method in a permafrost affected peatland. For this thesis, 5 ERT profiles were measured over 17 palsas and peat-plateaus in a palsa peatland environment in Tavvavuoma, northern Sweden, where the primary aim was to investigate the depth to the base of permafrost under the mounds.

  5. 39. Advanced processing of vertically aligned nanodevices

    University essay from Lunds universitet/Fysiska institutionen

    Author : Shantonu Biswas; [2013]
    Keywords : photoresist; S1800; photodetector; nanowire; metal contact; Technology and Engineering;

    Abstract : Lithography technique is highly dependent on the photoresist that is used for the processing of the nanodevices. S1800 series photoresist is probably the most used positive photoresist for UV-lithography process. READ MORE

  6. 40. Determination of Homogeneity and Isotropy of Soil Using Geophysical Methods.

    University essay from KTH/Mark- och vattenteknik

    Author : Danial Khatibi Asfanjani; [2013]
    Keywords : radial; homogeneity; isotropy; electrical resistivity; infiltration;

    Abstract : Cognition of the hydraulic properties of soils is important in civil and environmental projects such as for water supply, geotechnical investigations and evaluation of pollutant spreading. This pilot project aims to develop and test a new method for characterization of the homogeneity and isotropy of different soils by using geophysical measurements. READ MORE
