  1. 1. Electrically Modified Quartz Crystal Microbalance to Study Surface Chemistry Using Plasma Electrons as Reducing Agents

    University essay from Linköpings universitet/Kemi

    Author : Pentti Niiranen; [2021]
    Keywords : Plasma enhanced chemical vapor deposition; PECVD; Quartz crystal microbalance; QCM;

    Abstract : Metallic films are important in various applications, such as electric devices where it can act as contacts. In electrical devices, the substrate typically consists of silicon dioxide (SiO2) which is a temperature-sensitive substrate. READ MORE

  3. 2. Plasma density characteristics of magnetic holes near the Kronian magnetosphere boundary surfaces

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Marlon Luis Bause; [2020]
    Keywords : Magnetic holes; Saturn; Langmuir Probe; plasma electron density; Magnetosphere;

    Abstract : Localized structures of the magnetic field strength depression are often observed in the interplanetarymedium, and they are called ‘magnetic holes’ after the original work of Turner et al. 1977. A numberof observations of similar features have been reported, while the mechanisms of their origin have notfully understood yet. READ MORE

  4. 3. Electron heating in collisionless shocks observed by the MMS spacecraft

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Martin Svensson; [2018]
    Keywords : shocks; MMS; electron; heating; gradient; quasi-perpendicular; scaling; plasma; space;

    Abstract : Shock waves are ubiquitous in space and astrophysics. Shocks transform directed particle flow energy into thermal energy. As the major part of space is a collisionless medium, shocks in space physics arises through wave-particle interactions with the magnetic field as the main contributor.The heating processes are scale dependent.

  5. 4. Plasma diagnostics for particle confinement studies in magnetic fusion devices

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Linus Hägg; [2018]
    Keywords : Interferometry; Interferometer; double color interferometer; two-color interferometer; Fusion; Plasma; Fusion plasma; Spectroscopy;

    Abstract : This thesis investigates the performance and improves a double color interferometer setup, absolutely calibrates a line radiation Balmer H-alpha measurement setup, and uses measurements from both setups to estimate the particle confinement time of a plasma. The double colour interferometer at the magnetic confinement plasma device EXTRAP T2R measures the line integrated electron density of the plasma. 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.
