  1. 1. Mapping of contaminant dispersion from a polluted mining area by geochemical and geophysical methods, Rävlidmyran,northern Sweden : Use of geochemical and geophysical studies to investigate contaminants

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Astrid Theander; [2019]
    Keywords : ;

    Abstract : After open pit mining, the pit can either be backfilled or be filled with groundwater andbecome a pit lake. These lakes tend to be acidic and contains high concentrations ofmetals, which increases the environmental risks in the area. One of these pit lakes isRävlidmyran in the Skellefte ore district.

  2. 2. Transparent conductive oxides deposited by magnetron sputtering: synthesis and characterization

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Mathias Axelsson; [2019]
    Keywords : TCO; AZO; solar cell; magnetron sputtering;

    Abstract : The thesis has dealt with transparent conducting oxide (TCO) materials, with a focus on Al:ZnO and with studies on Sn:In2O3 and ZnO. TCOs are a material group that is used for its properties of being conductive and at the same time transparent. READ MORE

  4. 4. Processing and characterization of self-aligned Ni/Al and Co ohmic contacts to 4H-SiC

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Andrea Ferrario; [2018]
    Keywords : ;

    Abstract : New self-aligned silicide processes for the realization of Ni/Al and Co contacts to silicon carbide (4H-SiC) are presented and contacts are characterized using the transfer length method (TLM). Since cobalt silicide formation on 4H-SiC has not been investigated before, interface reaction between Co and 4H-SiC as well as the study on the annealing temperatures constitute an essential part of this work.

  5. 5. Characterization of the Electrical Resistivity and Water Sorption Properties of a Semiconducting Swelling Tape

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Maria Nicte Polanco Olsen; [2018]
    Keywords : ;

    Abstract : I närvaro av fukt och lokaliserade fältförbättringar kan vattenträd utvecklas inom polymerisoleringen av HV subsea kraftkablar. Vattenträd tenderar att växa obemärligt och försämra isolationsegenskaperna med tiden. Fuktigheten i isoleringen kan effektivt reduceras genom applicering av halvledande svällningsband. READ MORE
