Light emission from silicon with tin-containing nanocrystals

Søren Roesgaard, Jacques Chevallier, Peter I. Gaiduk +6

Tin-containing nanocrystals, embedded in silicon, have been fabricated by growing an epitaxial layer of Si_{1-x-y}Sn_{x}C_{y}, where x = 1.6 % and y = 0.04 %, followed by annealing…

Luminescence decay dynamics of germanium nanocrystals in silicon

Brian Julsgaard, Peter Balling, John Lundsgaard Hansen +2

The dynamics of the luminescence decay from germanium nanocrystals embedded in crystalline silicon has been studied for temperatures varied between 16 K and room temperature. At ro…

Tuning the plasmon resonance of metallic tin nanocrystals in Si-based materials

Mads Møgelmose Kjeldsen, John Lundsgaard Hansen, Thomas Garm Pedersen +2

The optical properties of metallic tin nanoparticles embedded in silicon-based host materials were studied. Thin films containing the nanoparticles were produced using RF magnetron…

Anomalous temperature dependence of the the spin-flip thermalization time between the dark and bright exciton states in silicon nanocrystals

Brian Julsgaard, Ying-Wei Lu, Peter Balling +1

Silicon nanocrystals are studied by time-resolved fluorescence spectroscopy. After laser excitation the bright and dark exciton ground state levels are populated at random, but sub…
