1. 1. Study of the Optical Properties of sp2-Hybridized Boron Nitride

   University essay from Linköpings universitet/Tillämpad optik

   Author : Eduardo Antunez de Mayolo; [2014]
   Keywords : Spectroscopic ellipsometry; boron nitride; optical properties; materials characterization; III-V nitride semiconductors; cathodoluminescence; electron microscopy; Raman spectroscopy;

   Abstract : Nitride-based semiconductor materials make it possible to fabricate optoelectronic devices that operate in the whole electromagnetic range, since the band gaps of these compounds can be modified by doping. Among these materials, the sp2-hybridized boron nitride has properties that make it a potential candidate for integration in devices operating in the short-wavelength limit, under harsh environment conditions, due to the strength of the B-N bond.

3. 2. Surface Optimization of the Silicon Templates for Monolithic Photonics Integration

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

   Author : Chen Hu; [2011]
   Keywords : Chemical mechanical polishing; epitaxial lateral growth; surface optimization; roughness; surface morphology; step height; surface topography.;

   Abstract : Silicon photonics is emerging as a potential field to achieve optical interconnects towards the realization of ultra high bandwidth. The indirect band-gap property of silicon still remains as a big challenge to incorporate silicon photonic active device, for example, silicon-based laser. READ MORE

4. 3. Probing the Toba super-eruption: Insights from oxygen isotope geochemistry and geobarometry

   University essay from Berggrundsgeologi

   Author : David Budd; [2011]
   Keywords : super-eruption; oxygen isotopes; geobarometry; Toba; magmatic plumbing; caldera;

   Abstract : The Toba caldera located in north Sumatra, Indonesia, is the source of the largest volcanic eruption in the Quaternary (Rose & Chesner 1987). Its enormous volume of 2800 km3 has been a matter of debate for decades and it is still unclear where and how the Toba magma was assembled. READ MORE

   Abstract : Nowadays, lighting represents 20% of the global electricity consumption. Light can be produced using different technologies but more than 100 years after its invention, the incandescent bulb is still the most sold and one of the more used light sources. READ MORE

6. 5. Internal structures in detrital zircons from Hamrånge: a study of cathodoluminescence and back-scattered electron images

   University essay from Lunds universitet/Geologiska institutionen

   Author : Karolina Bjärnborg; [2008]
   Keywords : zircons; internal structures; BSE; CL; Hamrånge; zirkoner; inre strukturer; zonering; metamiktisering; Earth and Environmental Sciences;

   Abstract : Syftet med denna studie var att extrahera och undersöka de inre strukturerna hos zirkoner från skifferprover insamlade i Hamrångeområdet, norr om Gävle,. Fyra prover från tre olika lokaler valdes ut för undersökningen. Studierna genomfördes med optiskt mikroskop samt svepelektronmikroskop, där back-scatter och katodluminescens användes. READ MORE
