1. 1. Flashlamp Annealing for Improved Ferroelectric Junctions

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Theodor Blom; [2023]
   Nyckelord :Flashlamp annealing; ferroelectricity; hafnia oxide; III-V semiconductor; thermal annealing; device performance; Technology and Engineering;

   Sammanfattning : The effects of flashlamp annealing (FLA) on the quality of ferroelectric HfxZr1–xO2 (HZO) interfaces, integrated on InAs substrates, are evaluated. For the integration of ferroelectric HZO on III-V semiconductors the crystallization via rapid thermal processing (RTP) can severely degrade the HZO/III-V interface. LÄS MER

3. 2. Influence of Nucleation Techniques on the Degree of Supercooling and Duration of Crystallization for Sugar Alcohol as Phase Change Material : Investigation on erythritol-based additiveenhanced Composites

   Master-uppsats, KTH/Energiteknik

   Författare :JiaCheng Lin; HaoRan Teng; [2019]
   Nyckelord :Phase Change Material; Latent Thermal Energy Storage; Temperature-history; Sugar Alcohols; Supercooling; Duration of crystallization; Crystallization; Solidification; Fasändringsmaterial; Latent Termisk Energilagring; T-history; Sockeralkoholer; Underkylning; Varaktighet av kristallisering; Kristallisering; Stelning;

   Sammanfattning : Utilizing Phase Change Materials (PCM) for Latent Thermal Energy Storage (LTES) applications have previously been extensively researched as a measure to reduce greenhouse gas emissions from energy consumption. In order to make use of the waste heat from industrial processes for LTES purposes, a new demand emerged for PCMs capable of phase change in mid-temperature ranges of 100 °C - 200 °C. LÄS MER

5. 4. Pretreatmenteffect on induction time and polymorphic outcome of tolbutamide crystallizationin 1-propanol

   Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

   Författare :Georgios Chondrogiannis; [2017]
   Nyckelord :Crystallization; Nucleation; Polymorphism; Solution history; Pretreatment;

   Sammanfattning : In this project, the effect of solution thermal and structural history on nucleation was investigated. Many researchers have shown that temperature and duration of pretreatment has an influence on induction time, polymorphic outcome and metastable zone width. LÄS MER
