1. Structural analysis of HZO thin film and electrode using X-ray diffraction
Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER
2. (1,3-di-tert-butyltriazenide) Cu(I) as vapor deposition precursor
Kandidat-uppsats, Linköpings universitet/KemiSammanfattning : In the past few decades, devices such as computers have become smaller, and their performance has improved beyond comparison. Semiconductors and interconnectors are used in almost all devices today and are made of thin films. LÄS MER
3. BCP Lithography Defined Arrays of InAs NWs Grown Using MOVPE with Au Seeds
Master-uppsats, Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/Fasta tillståndets fysikSammanfattning : In this report we outline a detailed process flow for a quick and inexpensive implementation of large dense arrays of InAs nanowires (NWs) grown in the reactive ion etching/etched (RIE) pores of a SiO2/SiNx mask on top of an InAs/Si(111) substrate. The self-assembled (hexagonally close-packed) pattern of poly(methyl-methacrylate) (PMMA) cylinders in a poly(styrene) (PS) matrix adopted by a linear diblock poly(styrene-block-methyl-methacrylate) P(S-b-MMA) block-copolymer (BCP) was transferred to the dielectric stack (consisting of a ≈10 nm plasma enhanced chemical vapour deposition/deposited (PECVD) SiNX layer topped by a thin atomic layer deposition/deposited (ALD) SiO2 film) using a two-step RIE procedure.

4. Elastic hyperspectral lidar for detecting coherent backscatter from insects
Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenSammanfattning : Insects play a major role in the ecosystem and are an important factor for biodiversity. Using laser remote sensing to distinguish and monitor the millions of insects in-situ, holds large potential to speed up and improve the otherwise time consuming process of trapping and subsequent analysis.

5. Study on the Electronic Band Structure of the Spinel Superconductor LiTi2O4
Master-uppsats, KTH/Tillämpad fysikSammanfattning : This master’s thesis focuses on investigating the electronic properties of the superconducting spinel compound LiTi2O4 by means of computational and experimental effort. The title compound has been extensively studied in the past years, being the only known superconducting spinel oxide with relatively high Tc = 11.5 K. LÄS MER
