  1. 1. Synthesis and thermoelectric properties of Cr1-xMexN (Me = Mo, V)

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Victor Rutberg; [2022]
    Keywords : Chromium nitride; thin films; thermoelectrics; physical vapour deposition; medium entropy alloy;

    Abstract : Among emerging materials systems for thermoelectric applications, the early transition-metal nitrides based on ScN and CrN show unexpectedly promising properties. These properties are determined by high Seebeck coefficient, low thermal conductivity, and high electrical conductivity. READ MORE

  2. 2. Investigating potential proton conductors: Doping BaTiO3 and SrTiO3 with Fe and Al

    University essay from Uppsala universitet/Strukturkemi

    Author : Julia Löfstrand; [2020]
    Keywords : Proton conductor; perovskite; solid state synthesis;

    Abstract : There are many interesting applications of proton conducting oxides, such as electrolytes in fuel cells, hydrogen sensors and catalytic membranes for hydrogenation or dehydrogenation of organic compounds. Previous work explored doping BaTiO3 with the Rare Earth Element (REE) Sc to introduce oxygen vacancies in the structure, making it a Proton Conductor (PC). READ MORE

  3. 3. Characterization of graphene-based sensors for forensic applications : Evaluating suitability of CVD graphene-based resistive sensor for detection of amphetamine

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

    Author : Ülle-Linda Talts; [2019]
    Keywords : Sensor systems; Chemical sensors; Nanosensors; Drug screening; Nanomaterials; Sensorsystem; Kemiska sensorer; Nanosensorer; Drug screening; Nanomaterial;

    Abstract : Recent improvements in sensor technology and applications can be partly attributed to the advancements in microand nanoscale fabrication processes and discovery of novel materials. The emergence of reliable and inexpensive methods of production of monolayer materials, such as graphene, has revealed the advantageous electronic properties which when utilized in sensory elements can significantly enhance response to the input signal.

  4. 4. Electronic structure calculations of defects in diamond for quantum computing : A study of the addition of dopants in the diamond structure

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Diana Elisa Murillo Navarro; [2019]
    Keywords : Density Functional Theory; Quantum computing; Diamond; Dopants; Quantum physics; NV color center;

    Abstract : When doing computations on the negatively (positively) charged NV-center in diamond, the common procedure is to add (subtract) an electron from the system. However, when using periodic boundary conditions, this addition/subtraction of an electron from the supercell would result in a divergent electrostatic energy. READ MORE

  5. 5. Doped 3C-SiC Towards Solar Cell Applications

    University essay from Linköpings universitet/Halvledarmaterial

    Author : Mattias Jons; [2018]
