2. 1. Spin splitting in open quantum dots and related systems

   Author : Martin Evaldsson; Igor Zozoulenko; Igor Abrikosov; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mesoscopic systems; 2DEG; ballistic transport; quantum dots; spin-polarised transport in quantum dots; spontanueous spin-splitting; Mesoscopic physics; Mesoskopisk fysik;

   Abstract : This thesis addresses electron spin phenomena in semi-conductor quantum dots/anti-dots from a computational perspective. In the first paper (paper I) we have studied spin-dependent transport through open quantum dots, i.e., dots strongly coupled to their leads, within the Hubbard model. READ MORE

4. 2. Computational Modelling of Organic Bioelectronic Devices and Materials

   Author : Najmeh Delavari; Igor Zozoulenko; Mathieu Linares; Brett Savoie; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Bioelectronics being the intersection field between electronics and biology, aims to investigate the transduction between electronic signals and ionic signals within a biological environment. Organic materials such as conducting polymers are extensively utilized in the fabrication and development of bioelectronic devices due to their ability to conduct both electrons and ions. READ MORE

5. 3. Quantum transport and spin effects in lateral semiconductor nanostructures and graphene

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Nowadays, electronic devices that include conducting polymers, ranging from batteries and OLED panel for TVs and smartphones to bioelectronics devices such as sensors and ion-pumps for drug-delivery are widely used in our life. The use of conducting polymer in many electronic applications was driven by demand for light weight, flexibility or biocompatibility with the performance on pair with conventional inorganic counterparts.
