In this project we will research disordered magnetic alloys from first principles. Researching magnetic properties of disordered alloys is essential for the knowledge of phase transformations in alloys and also from the viewpoint of fundamental concerns of magnetism in solids. Actually Disorder in a magnetic system can lead to unusual magnetic structures, as an example spin glass, which have somewhat unusual features.
The interaction between light and organometallic chromophores has been looked into theoretically in a strive for fast optical filters. The key focus is on two-photon absorption and excited state absorption as highlighted in the Jablonski diagram. We stress the need for relativistic
Organic electronics is a rapidly evolving field with large number of applications having high possibility of commercial success. Even though a great progress has been created, many organic electronic applications: organic light-emitting diodes (OLEDs), organic field effect transistors (OFETs), organic solar cells,
There are many different codes available for making molecular dynamic simulation. Most of these are focused on high performance mainly. We have moved that focus towards modularity, flexibility and user friendliness. Our goal has been to design a software that is easy to use, can handle many different kind of simulations and is easily extendable to meet new requirements.
This thesis concerns quadratic response properties and their application to properties in Jablonski diagrams such as resonant two-photon absorption and excited state absorption. Our main interest lies in optical power limiting applications, and in this context, molecules containing heavy metal atoms prove superior.
Label-free detection of DNA has been successfully demonstrated on field effect transistor (FET) based devices. Since conducting organic materials was discovered and have attracted more and more research efforts by their profound advantages, this work will focus on utilizing an organic field effect transistor (OFET) as DNA sensor.
In this thesis we explore in particular the dynamics of a special type of quasi-particle in pi-conjugated materials termed polaron, the origin of which is intimately related to the strong interactions between the electronic and the vibrational degrees of freedom within these systems.
Integrated optics, by which optical devices are fabricated on a chip, is really a speedily growing field. Integrated optics is different from free-space optics in the manner which performs that will usually need bulky equipment in free-space optics, are put together on
The main goal of this thesis is to investigate the feasibility of a quadrature radio frequency receiver front-end using a second-order sampling topology in CMOS. Second-order sampling combines subsampling with a non-uniform sampling scheme. This non-uniform sampling scheme comprises of two uniform sampling streams with a small time delay between both streams, which allows the generation of an I and Q channel.
Ellipsometry is an optical technique used for studies of thin films and surfaces. The technique is based on measurement and analysis of the changes in the state of polarization that occur when polarized light is reflected on a sample surface. The multichannel
