Using Shape to Turn off Blinking for Two-Colour Multiexciton Emission in CdSe/CdS Tetrapods
Semiconductor nanostructures capable of emitting from two excited states and thereby of producing two photoluminescence colours are of fundamental and potential technological significance. In this limited class of nanocrystals, ...
Propagation and Absorption of Light in Planar Dielectric Waveguides with Two-Dimensional Semiconductors
(Optical Soc Amer, 2017-09-12)
Strong optical responses of atomically thin two-dimensional (2D) semiconductors make them attractive candidates for integration into various photonic and optoelectronic structures. We discuss some fundamental effects of ...
Energy Transfer from Colloidal Nanocrystals into Si Substrates Studied via Photoluminescence Photon Counts and Decay Kinetics
We use time-resolved photoluminescence (PL) kinetics and PL intensity measurements to study the decay of photoexcitations in colloidal CdSe/ZnS nanocrystals grafted on SiO₂ - Si substrates with a wide range of the SiO₂ ...
Chemical Bonding and Defect States of LPCVD Grown Silicon-Rich Si₃N₄ for Quantum Dot Applications
(A V S: Science & Technology of Materials, Interfaces, and Processing, 2014-03)
Si-rich Si₃N₄ (SRN) thin films were investigated to understand the various defect states present within the SRN that can lead to reduced performance in quantum dot based devices made of these materials. The SRN films, ...
