    Fabrication and characterization of Si1−xGex nanocrystals in as-grown and annealed structures: a comparative study 
    Sultan, Muhammad Taha; Maraloiu, Adrian Valentin; Stavarache, Ionel; Gudmundsson, Jon Tomas; Manolescu, Andrei; Teodorescu, Valentin Serban; Ciurea, Magdalena Lidia; Svavarsson, Halldor (Beilstein Institut, 2019-09-17)
    Multilayer structures comprising of SiO2/SiGe/SiO2 and containing SiGe nanoparticles were obtained by depositing SiO2 layers using reactive direct current magnetron sputtering (dcMS), whereas, Si and Ge were co-sputtered using dcMS and high-power impulse ...

    Influence of Phosphorus on Current Efficiency in Aluminum Electrolysis at Different Current Densities 
    Meirbekova, Rauan; Haarberg, Geir Martin; Thonstad, Jomar; Saevarsdottir, Gudrun Arnbjorg (The Electrochemical Society, 2017)
    Many factors may contribute to loss of current efficiency (CE) in aluminum reduction and one of them is a presence of impurities. In this work, the effect of phosphorus on CE is studied in a laboratory cell at different current densities. Due to a ...

    Piezoresistance characterization of silicon nanowires in uniaxial and isostatic pressure variation 
    Aghabalaei Fakhri, Elham; Plugaru, Rodica; Sultan, Muhammad Taha; Kristinsson, Thorsteinn; Árnason, Hákon Örn; Plugaru, Neculai; Manolescu, Andrei; Ingvarsson, Snorri; Svavarsson, Halldor (MDPI AG, 2022-08-23)
    Silicon nanowires (SiNWs) are known to exhibit a large piezoresistance (PZR) effect, making them suitable for various sensing applications. Here, we report the results of a PZR investigation on randomly distributed and interconnected vertical silicon ...

    Refractometric Sensing with Periodic Nano-Indented Arrays: Effect of Structural Dimensions 
    Carney, Daniel; Svavarsson, Halldor; Hemmati, Hafez; Fannin, Alexander; Yoon, Jae; Magnusson, Robert (MDPI AG, 2019-02-21)
    Fabrication and sensor application of a simple plasmonic structure is described in this paper. The sensor element consists of nano-patterned gold film brought about from two-dimensional periodic photoresist templates created by holographic laser ...
