4. 3. Engineering Epitaxial Graphene for Quantum Metrology

   Författare :Hans He; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Epitaxial Graphene; Magnetotransport; Quantum Resistance Metrology; Chemical Doping;

   Sammanfattning : Quantum resistance metrology deals both with the precise and accurate measurement of electrical resistance, by utilizing the quantum hall effect (QHE) in two-dimensional electron gases (2DEGs) such as those based on gallium arsenide (GaAs). Due to the unique properties of graphene, and specifically epitaxial graphene grown on silicon carbide (SiC/G), quantum Hall resistance (QHR) standards based on graphene perform better in a wider parameter space (temperature, current and magnetic field) than conventional semiconducting materials.

5. 4. Chemical Doping of Conjugated Polymers for Thermoelectric Applications

   Författare :Mariavittoria Craighero; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mechanical properties; conjugated polymers; solid-state order; organic thermoelectrics; chemical doping;

   Sammanfattning : The ongoing development of interconnected and wearable small devices, which together make up the so-called Internet of Things, is driving a rising need for autonomous and on-site energy supplies. Heat, an abundant and often wasted energy source, can be harnessed through thermoelectric generators that can directly convert heat into electricity. LÄS MER

7. 5. Computational study of Polymerization, Crystallization and Mechanical Properties of Conducting Polymers

   Författare :Donghyun Kim; Igor Zozoulenko; Xavier Crispin; Mathieu Linares; Yun Hee Jang; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : 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.
