1. ## 1. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning

University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

Keywords : Physics and Astronomy;

Abstract : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. READ MORE

2. ## 2. Transverse Momentum Spectra in pp collisions (\sqrt{s}\) = 7 TeV and $$\sqrt{s}$$ = 13 TeV in ALICE

University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikelfysik

Abstract : In this project particle production as a function of transverse momentum ($$p_{\rm T}$$) in proton-proton collisions at a center-of-mass energy ($$\sqrt{s}$$) of 7 TeV and 13 TeV has been studied. The transverse momentum is interesting to study since it reflects momentum created in the collision (before the collision, all momentum is in the beam - going in a longitudinal direction) and therefore gives information on the collision dynamics.

3. ## 3. THE COUPLING OF A DOUBLE QUANTUM DOT TO MICROWAVE PHOTONS

University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

Abstract : In this study, we derive a mathematical description of a double quantum dot (DQD) embedded in a microwave resonator starting from classical electrostatics. DQDs are a promising platform for building quantum computers and have important applications in quantum sensing and the study of light-matter interactions. READ MORE

4. ## 4. Chemoreception of a Two-Dimensional Cell with Multilayer Diffusion

University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

Abstract : Previously, Berg and Purcell found an expression for the diffusion current of particles into a set of receptors in their paper Physics of Chemoreception. These receptors were assumed to be uniformly distributed on a spherical cell's surface and the receptors where idealized as circular patches. READ MORE

5. ## 5. Error propagation in nuclear models

University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

Keywords : Physics and Astronomy;

Abstract : In this thesis we perform error analysis of a nuclear model based on density-functional theory developed in Lund. The Lund model allows us to perform calculations of nuclear spectra more efficiently by constructing a simple effective Hamiltonian reproducing the quadrupole deformation and pairing interaction strength parameters of a spherical Hartree-Fock reference functional.
