11. Life Cycle Assessment of Paper Based Printed Circuits
Sammanfattning : Printed circuit boards have been massively manufactured and wildly used in all kinds of electronic devices during people’s daily life for more than thirty years since the last century. As a highly integrated device mainly consists of silicon base, an etched copper layer and other soldered components, massive production of printed circuit boards are considered to be environmentally unfriendly due to the wet chemical manufacturing mode and lack of recycling ability.

12. Integration of silicide nanowires as Schottky barrier source/drain in FinFETs
Sammanfattning : The steady and aggressive downscaling of the physical dimensions of the conventional metal-oxide-semiconductor field-effect-transistor (MOSFET) has been the main driving force for the IC industry and information technology over the past decades. As the device dimensions approach the fundamental limits, novel double/trigate device architecture such as FinFET is needed to guarantee the ultimate downscaling. LÄS MER
13. The O2 electrode performance in the Li-O2 battery
Sammanfattning : Li-O2 batteries have been attracting increasing attention and R&D efforts as promising power sources for electric vehicles (EVs) due to their significantly higher theoretical energy densities compared to conventional Li-ion batteries. The research presented in this thesis covers the investigation of factors influencing the decomposition of Li2O2, the development of highly active electrocatalysts, and the design of low-cost and easy-operation binder-free O2 electrodes for Li-O2 batteries.

14. Programming Abstractions and Optimization Techniques for GPU-based Heterogeneous Systems
Sammanfattning : CPU/GPU heterogeneous systems have shown remarkable advantages in performance and energy consumption compared to homogeneous ones such as standard multi-core systems.Such heterogeneity represents one of the most promising trendsfor the near-future evolution of high performance computing hardware.

15. CVD solutions for new directions in SiC and GaN epitaxy
Sammanfattning : This thesis aims to develop a chemical vapor deposition (CVD) process for the new directions in both silicon carbon (SiC) and gallium nitride (GaN) epitaxial growth. The properties of the grown epitaxial layers are investigated in detail in order to have a deep understanding. LÄS MER
