1. 16. Development of Nanoimprint Lithography for Fabrication of Electrochemical Transducers

   Författare :Marc Beck; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electrochemistry; interdigitated array; anti-adhesion; anti-sticking; stamp; mold; monolayer deposition; Fysik; post-imprint processes; Physics; transducer; nanoimprint lithography; sensor; Fysicumarkivet A:2003:Beck;

   Sammanfattning : This thesis gives an overview about the current status of nanoimprint lithography, a relatively new nanofabrication tool. The technology is capable for parallel mass production of nm-structured features having a resolution below 10 nm and is usable with high throughput on full wafer scale. LÄS MER

3. 17. Transient electrochemical methods for investigation of porous battery electrodes

   Författare :Anton Lundqvist; KTH; []
   Nyckelord :electrochemical iimpedance spectroscopy; limn2o4; mathematical modelling; metal hydride; mcroelectrode; porous electrode; potential step; state of charge;

   Sammanfattning : This thesis treats electrochemical methods used to studybattery materials. Two different types of materials are used asmodel systems in this study, metal hydride alloys used in thenickel-metal hydride battery and LiMn2O4suggested for use in the lithium-ion battery. Thetwo model systems are used to critically analyse differentexperimental methods. LÄS MER

4. 18. Electrochemical Deposition and Characterization of Thermoelectric Thin Films of Bismuth Telluride and Its Derivatives

   Författare :Yi Ma; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; efficiency; deposition mechanism; thermoelectric properties; Thermoelectric; thin films; bismuth telluride and its derivatives; nano-engineering; electrochemical deposition;

   Sammanfattning : Thermoelectric materials have attracted enormous academic and industrial interest recently due to the fact that they can be used in solid state devices for power generation and cooling applications. It is expected that such thermoelectric applications will eventually contribute to meet the energy challenge in the future if the performance of the current devices can be further promoted through an increase in thermoelectric efficiency of the materials.
