16. Towards graphene-based devices: Fabrication and characterization
Sammanfattning : Graphene is a new material with a large set of impressive properties, interesting both for fundamental studies and applications. Reliable synthesis of large-scale, high-quality graphene is key to its future success. LÄS MER
17. Optical Investigations of Chiral Liquid Crystals
Sammanfattning : Optical investigations of course involve experimental work, but a theoretical basis is also needed. The first chapter can hopefully can give the non-expert an insight into the science of liquid crystals. Liquid crystals are optically birefringent, and a review of the phenomenon of birefringence follows in chapter 2. LÄS MER
18. Chiral Liquid Crystalline Side-Chain Polymers. Design, Synthesis and Properties
Sammanfattning : The potential use of chiral liquid crystalline materials, low molar mass as well as polymers, in technical applications has been recognized for some decades now. A number of interesting phenomena based on the spontaneous ordering of the liquid crystal forming molecules are strong reasons for the research effort in this area. LÄS MER
19. Liquid crystalline polymers for nonlinear optics : pyroelectric polymers and ferroelectric dendrimers
Sammanfattning : This thesis deals with liquid crystalline materialsincluding monomers, side-chain polymers, crosslinked polymers,and dendrimers. The materials are pyroelectric, meaning thatthere is a macroscopic electric polarization in the material,which is energetically stable in the absence of externalfields. LÄS MER
