1. 11. Identification of process induced defects affecting the performance of nanowire based solar cells by spatially resolved photocurrent measurements

   University essay from Lunds universitet/Fasta tillståndets fysik

   Author : Calvin Kan; [2013]
   Keywords : Nanowires; solar cells; nanotechnology; sustainable development; photocurrent measurements; energy; Technology and Engineering;

   Abstract : Solar power clearly has one of the greatest potential among renewable energy but a big setback is that it is still relatively expensive. Engineering of materials on a nanoscale, e.g. READ MORE

3. 12. Cryogenic Etching of the Electroplating Mold for Improved Zone Plate Lenses

   University essay from KTH/Tillämpad fysik

   Author : Daniel Larsson; [2010]
   Keywords : etching; plasma etching; zone plate; x-ray; nanofabrication; sidewall passivation; cryo; cryogenic; undercut;

   Abstract : The fabrication of zone plate lenses that are used for focusing X-rays relies on nanofabrication techniques such as e-beam lithography, reactive ion etching, and electroplating. The circular grating-like zone plate pattern can have a smallest half-period, a so-called zone width, of down to 20 nm while it also needs to have a height that is 5 to 10 times the zone width to have good diffraction efficiency.

4. 13. Optical components of XUV monochromator : For use in laser based angle-resolved photoemission spectroscopy

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Andreas Östlin; [2010]
   Keywords : ;

   Abstract : At the division of Material Physics at KTH an angle resolved photoemission spectrometer (ARPES) is being built. This system uses a pulsed laser to create ultraviolet light through higher harmonic generation. The laser has a high output effect which puts the optical components of the system under a large heat load. READ MORE
