2. 11. Optical studies of crystal phase heterostructures

   Author : Irene Geijselaers; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; III-V semiconductor nanowires; photoluminescence; photoluminescence excitation; polytype; crystal phase heterostructure; InP; GaAs; wurtzite; Fysicumarkivet A:2021:Geijselaers;

   Abstract : III-V semiconductors are commonly used for a variety of optical applications, such as LED based lights and solar sells. Most III-V semiconductors, such as GaAs and InP, exhibit the zinc-blende (zb) crystal structure, but in the form of nanowires it is also possible to create them in the wurtzite (wz) crystal structure.

7. 15. Excitonic Effects and Energy Upconversion in Bulk and Nanostructured ZnO

   Author : Shula Chen; Irina Buyanova; Weimin Chen; Detlev M. Hofmann; Linköpings universitet; []
   Keywords : ;

   Abstract : Zinc Oxide (ZnO), a II-VI wurtzite semiconductor, has been drawing enormous research interest for decades as an electronic material for numerous applications. It has a wide and direct band gap of 3.37eV and a large exciton binding energy of 60 meV that leads to intense free exciton (FX) emission at room temperature. READ MORE
