  1. 1. Chromia-Alumina Thin Films from Alkoxide Precursors : From Precursor Synthesis to Deposition and Characterisation

    University essay from Uppsala universitet/Oorganisk kemi

    Author : Elina Elvelo; [2023]
    Keywords : alkoxide; synthesis; thin film; coating; alumina; chromia; spinodal decomposition;

    Abstract : A hetero-bimetallic alkoxide CrAl3(OiPr)12 was synthesised through metathesis of achromium(III)chloride THF complex (CrCl3 . 3 THF) and 3 KAl(OiPr)4.It was used as a single sourceprecursor to make oxide powders and films with 1:3 chromium/aluminium compositionthrough sol-gel synthesis.

  5. 4. Growth and Characterization of CrB2/TiB2 Superlattices by Magnetron Sputtering

    University essay from Linköpings universitet/Tunnfilmsfysik; Linköpings universitet/Tekniska fakulteten

    Author : Samira Dorri; [2019]
    Keywords : Thin films; diborides; superlattices; reflectivity; transition-metal diborides; CrB2; TiB2;

    Abstract : In the present work, growth and structural characterization of CrB2/TiB2 superlattices on (0001) Al2O3 substrate is studied. The superlattices are grown using a direct current magnetron sputtering (DCMS) system with a base pressure of <9E-7 Torr. READ MORE

  6. 5. Rear side BSF/emitter patterning of SHJ-IBC solar cells using selective deposition and hydrogen plasma etching of a-Si:H

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Mahmudul Hasan; [2016]
    Keywords : ;

    Abstract : Silicon heterojunction interdigitated back-contact (SHJ-IBC) solar cells have attracted considerable attention because of their potential to achieve very highly efficiency. However, the back contacting scheme leads to additional fabrication complexity mainly resulting from the formation of interdigitated n- (back surface field (BSF)) and p-type (emitter) hydrogenated amorphous silicon (aSi:H) strips.
