1. A study of the triboelectricity of 2D materials: MoS2, WS2 and MoO3 : Analyzing measurements from a triboelectric nanogenerator
Kandidat-uppsats, Mittuniversitetet/Institutionen för naturvetenskapSammanfattning : Detta projekts mål har varit att undersöka tre olika 2D-materials triboelektriska egenskaper och därmed placera dem i en triboelektrisk serie. Detta utfördes genom att använda en triboelektrisk nanogenerator (TENG) och mäta den resulterande spänningen. Tio stycken motmaterial applicerades mot varje 2D-material på nanogeneratorn. LÄS MER
2. First Principles Studies Of 2D Magnets
Kandidat-uppsats,Sammanfattning : The aim of this project is to examine the electric and magneticproperties of three monolayer chromium trihalides when doped withdifferent transitions metals, that is CrXY_6, where X=(Mn,Fe,Co,Ni,V)and Y=(Cl,Br,I). The calculations were made using the software programQuantum Espresso that used density functional theory to solveSchrödinger’s equation. LÄS MER
3. 2D-material nanocomposites with nonlinear optical properties for laser protection
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Lasers are increasingly used for a wide range of different applications for both civil and military purposes. Due to the distinct properties of laser light, use of lasers often comes with a risk of damage to the human eye and other optical sensors. Therefore, an effective laser protection is needed. LÄS MER
4. Black phosphorous sample preparation for ultrafast electron diffraction studies
Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : Since 2004 when mechanical exfoliation was first utilised to produce single layered samples of graphite, 2D materials have gained interest in the scientific community. With the prerequisite that the initial bulk material has a layered structure, these 2D materials have created an opportunity to examine materials on a very small scale as well as opening the possibility of creating smaller electrical components for industrial and commercial use, with well-known and documented parameters.

5. Angular dependence of the Raman active phonon modes of Black Phosphorus
Magister-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : This Master’s project presents on the angular dependence of the intensity of the Raman active phonon modes of Black Phosphorus (BP), a layered 2D material with unique and attractive characteristics to the scientific and engineering community. Raman spectroscopy is an indispensable tool in quick and unobtrusive analysis of chemical structures. LÄS MER
