Acoustic Flow Control

You have heard about the latest Nobel prize in Physics regarding Optical tweezers to manipulate small object. In this Diploma work/Master thesis project you will instead study an acoustic tweezer.

The goal of this project is to utilize a novel MEMS-based ultrasonic speaker array and advanced beam-forming strategies to produce acoustic traps and affect the position of minute electronic components. The experimental platform will be provided by MyVox. The experiments will probe the validity of component manipulation with respect to component size, and positioning and motion stability. The project will include stages for literature review, design, design review, setup build, testing and documentation.

Implementing Novel Organic Supercapacitors in Energy Harvesting Systems​

The project aims at developing a demonstrator that utilizes the organic supercapacitor as the energy storing component for an energy harvesting system that can power up devices such as wireless sensors or terminals. The work will be carried out at Rise Acreo in Norrköping.​

1- Growth of epitaxial graphene on C face of SiC and its characterization
The project is based on the growth of graphene on SiC substrates using thermal decomposition (sublimation) method. It also involves characterization of graphene using atomic force microscopy, optical microscopy, contactless measurements of charge carrier density and mobility as well as micro-Raman spectroscopy. We seek a materials science and growth interested master thesis student in growth of graphene and production oriented research.

2- Surface functionalization of epitaxial graphene on SiC using two dimensional material for sensing application

In this research project, the epitaxial graphene layers will be grown on Si-face of SiC substrates using thermal decomposition method. We will use different coverage of monolayer and bilayer graphene on SiC as a substrate. The chemically doped nano size 2D materials (such as BN) will be used for surface functionalization of epitaxial graphene. Different dopants (e.g.Cl, N, K, Na) with two different concentration will be used to compare the effectiveness for each dopant and to modify the surface functional groups of nano size 2D materials. They will be distributed uniformly on the surface of epitaxial graphene, and then morphology, structural, electrical properties of the samples will be characterize with different methods (e.g. AFM, SEM, Raman spectroscopy ...). After charactering the samples, functionalized samples with doped 2D materials will be used for making sensor devices.

3- The effect of oxygen on epitaxial graphene on SiC
The aim of this project is study of surface morphology, structure and electronic modifications of epitaxial graphene layers for different steps of the oxidation process. We also want to check if oxygen partially can decouple the buffer layer from the substrate and hence reduce the effect of SiC substrate to graphene layers. This diploma work will include different characterization techniques of graphene layers on SiC substrates before and after oxidation.
