Using an approach of combining Fourier transform infrared spectroscopy with resonant illumination from a secondary external light source, we have measured the photocurrent (PC) for multiple layers of self-assembled InAs dots embedded in a matrix of InP. Without external illumination, we observe photoexcitation of electrons from bound states in the dots to the InP barrier. By additional illuminatio
A theory of self-induced transparency for a TM-mode propagating in a planar semiconductor waveguide sandwiched between two dielectric media is developed. A transition layer between the waveguide and one of the connected media is described using a model of a two-dimensional sheet of quantum dots. Explicit analytical expressions for the optical soliton in the presence of single-excitonic and biexcit
Entanglement production is one of the properties of interest when studying nanoscale systems. Not only does entanglement between subsystems hints at other non-classical behaviour and effects that may be of interest to applications; the resource of entangled systems themselves is one on which many future devices and protocols may depend on. In this thesis work, a system of two quantum dots coupled
There is an increasing demand for alternative in vitro methods to replace animal testing, and, to succeed, new methods are required to be at least as accurate as existing in vivo tests. However, skin sensitization is a complex process requiring coordinated and tightly regulated interactions between a variety of cells and molecules. Consequently, there is considerable difficulty in reproducing this
The complex interplay by tunneling and scattering in quantum cascade lasers is analyzed with nonequilibrium Green's functions. Data for a recently proposed simple structure based on only two wells per period is presented. This simple structure allows to visualize the relevance of the tunneling resonance very clearly. It is argued that a QCL design needs at least three levels per period, thus furth
Sorption balances are instruments in which samples are weighed as they are exposed to a programmed relative humidity (RH). Such instruments are used to measure sorption isotherms and to study solid-vapour interaction. There are different methods to validate the performance of the RH generation in such instruments by charging them with saturated salt solutions and ramping/stepping the RH past the d

We demonstrate that we can use the extreme ultraviolet radiation produced by high order harmonic generation to perform photoionization experiments. With harmonics from the 11th to the 69th of a 140 fs Cr:LiSAF laser operating at 825 nm, we measure the relative photoionization cross sections of xenon, krypton, argon and neon over the range 10 to 110 eV. With narrow bandwidth harmonics produced by a
I play cement Halla Steinunn Stefánsdóttir ‘I play cement’ (2019) is an audio and video installation for a screen and eight speakers. The footage was filmed and recorded in summer and winter 2017-18 as I navigated through a cement factory, situated by the mouth of Elliðaár in Reykjavík, Iceland. The work was later created at Lund University’s Inter Arts Center in Malmö, Sweden. ‘I play Cement’ con

Herein, a model is developed to study the polarization-selective light-coupling in quantum well infrared photodetector arrays with 15 and 30 μm pixel pitch. The polarization-selective light-coupling is achieved using 1D lamella gratings with varying grating orientation and studied through 2D and 3D finite-element method simulations. The extracted absorption quantum efficiency ηabs, derived from th
The PhD programme in Computational Science concerns the scientific studies which applies and develops computational methods for advanced computing with the aim of solving research problems in natural science, technology or medicine. The doctoral education leads to a Phil. Dr. degree at Lund University. It normally takes four years of full-time studies, of which approximately one year is devoted to
