1. 1. Magnetron Sputter Epitaxy of High-quality GaNand Plasma Characterization of the Process : Degree Project–Master’s Thesis

   Master-uppsats, Linköpings universitet/Tunnfilmsfysik

   Författare :Yi-Ling Lo; [2021]
   Nyckelord :GaN; Semiconductors; Nanomaterials; Thin film; Magnetron Sputtering; Epitaxy; XRD; Physical Vapor Deposition;

   Sammanfattning : Several sputtering depositions were done by direct current (DC) magnetron sputtering epitaxy (MSE) techniquefor the goal of improving the growth rate and crystalline quality of GaN thin film on Al2O3 substrate. Thegrowth rate was higher when substrate-to-target distance D = 7 cm compared with D = 9. LÄS MER

3. 2. Sputtering of High Quality Layered MoS2 films

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

   Författare :Sari Abid Al Shaybany; [2020]
   Nyckelord :MoS2; molybdenum; molybdenum disulfide; sputtering; magnetron sputtering; high quality; sulfur; H2S; argon; pressure; temperature; high temperature; monolayer; few layers; large scale;

   Sammanfattning : We have deposited bulk, monolayer and few-layers as well as large-scale 2D layered MoS2 thin films by pulsed DC magnetron sputtering from an MoS2 target. MoS2 has gained great attention lately, together with other layered Transition Metal Dichalcogenides (TMDCs), for its unique optical and electrical properties with thickness-dependent bandgap.

4. 3. Gas flow sputtering of Cu(In,Ga)Se2 with extra selenium supply

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

   Författare :Marcus Turunen; [2015]
   Nyckelord :Gas flow sputtering; CIGS; selenium; thin film; solar cell;

   Sammanfattning : In this thesis CIGS absorber layers have been deposited by gas flow sputtering with an extra supply of selenium, a method that displays promise for large scale production because of its one-step sputtering route which deposits low energy particles in a high deposition rate. In this thesis a method was developed where selenium was added to the sputtering process inside the sputter chamber in a controllable manner and in larger amount than done in previous projects.

5. 4. Development of novel materials for solar cells

   Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

   Författare :Klara Takei; [2015]
   Nyckelord :Sputter target; CIGSe; chalcopyrite; compound; mechanical alloying; milling; hot pressing;

   Sammanfattning : More efficient and cheaper solar cells are necessary if photovoltaics are to play a major rolein the field of sustainable power generation. Copper indium gallium selenide (CIGSe) is one of the best suited materials for thin film solar cell absorbers. LÄS MER

7. 5. Evaluation of Cu2ZnSnS4 Absorber Films Sputtered from a Single, Quaternary Target

   Uppsats för yrkesexamina på avancerad nivå, Institutionen för kemi - Ångström

   Författare :Liv Carlhamn Rasmussen; [2013]
   Nyckelord :Cu2ZnSnS4; CZTS; kesterite; sputtering; compound; quaternary;

   Sammanfattning : Cu2ZnSnS4 (CZTS) is a promising absorber material for thin-film solar cells since it contains no rare or toxic elements, has a high absorption coefficient and a near ideal bandgap energy. It does, however, present some challenges due to the limited single-phase region of the desired kesterite phase and its instability towards decomposition. LÄS MER
