How can I precisely determine the type of defects and energy of defects inside of CsPbBr3 nanocrystals?

05 May 2018 0 4K Report

Fitting photoluminescence lifetime decay curves with 2-exponential model indicates two types of decay paths for photons inside of CsPbBr3 semiconductors. I am guessing this 2-exponential arises due to the surface states within the bandgaps of CsPbBr3. I need to precisely determine the type of defects and energy of defects inside of CsPbBr3 nanocrystals. How can I do these measurements experimentally?

How the Ground Plane implantation is performed without damaging (and w/o varying the undoped nature) the top Si (8-10 nm) in FDSOI technology ?

It is a general practice to introduce Ground Plane in FDSOI devices under the BoX. The Ground Planes are introduced by Ion Implantation through Top Si layer and Buried Oxide. I wanted to know that...
