2. 1. Charge carrier dynamics in colloidal quantum dots: Tracking the dance of electrons and holes by ultrashort laser pulses

   Author : Nils Lenngren; Kemisk fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; CdSe; quantum dots; ultrafast spectroscopy; charge carrier dynamics;

   Abstract : Quantum dots (QDs) are semiconductor nanocrystals with quantum confinement. This thesis uses various time-resolved spectroscopic techniques to study ultrafast charge carrier dynamics in colloidal CdSe quantum dots that are important both from a theoretical point of view and for their relevance for solar cell applications.

4. 2. High-order accurate calculations and bounds on effective properties of composites

   Author : Henrik Christiansson; KTH; []
   Keywords : ;

   Abstract : A classical problem in material science has been the studyof electrostatic and elastostatic properties of compositematerials. The complexity of the microstructure of randomcomposite media makes an exact calculation of the effectiveproperties very difficult. READ MORE
