6. Ultraviolet vertical-cavity surface-emitting lasers and vertical microcavities for blue lasers
Sammanfattning : III-nitride materials are used for ultraviolet (UV) and visible light emitters. One such light source is the vertical-cavity surface-emitting laser (VCSEL) that could find applications within areas ranging from sterilization and medical treatment to car headlights and augmented reality displays.

7. Silicon nanofabrication by electron beam lithography and laser assisted electrochemical etching
Sammanfattning : .... LÄS MER
8. Development of Nanoimprint Lithography for Fabrication of Electrochemical Transducers
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
9. Silicon nanowires, nanopillars and quantum dots : Fabrication and characterization
Sammanfattning : Semiconductor nanotechnology is today a very well studied subject, and demonstrations of possible applications and concepts are abundant. However, well-controlled mass-fabrication on the nanoscale is still a great challenge, and the lack of nanofabrication methods that provide the combination of required fabrication precision and high throughput, limits the large-scale use of nanodevices.

10. Characterising Dental Implant Surfaces by Topographical, Electrochemical, and Biomechanical Methods
Sammanfattning : Replacement of extracted teeth by dental implants was first introduced in the 1950’s. From the beginning, threaded titanium implants with smooth surfaces were used. Later on, screw shaped implants with micro-scaled roughened surfaces were introduced showing bone ingrowth and improved in vivo and in vitro results and good long term stability. LÄS MER
