1. 1. Synthesis and properties of single luminescent silicon quantum dots

   Författare :Ilya Sychugov; Jan Linnros; Tom Griegorkiewich; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Condensed matter physics; Kondenserade materiens fysik;

   Sammanfattning : Silicon is an ubiquitous electronic material and the discovery of strong room temperature luminescence from porous Si in 1990 raised hopes it may find a new lease of life in the emerging field of optoelectronics. First, the luminescence was shown to be emitted from nanostructures remained in a porous Si network. LÄS MER
