Abstract :
Summary form only given. Auger effects play an important role in all types of materials systems from atoms and molecules to bulk semiconductors. The efficiency of Auger effects is greatly reduced in bulk materials, due to the reduced Coulomb electron-electron coupling and kinematic restrictions imposed by energy and momentum conservation. In the present work, to quantitatively study the modification of Auger-type interactions during a gradual transformation from the atomic/molecular to bulk-crystalline regimes we use chemically-synthesized nanoparticles or quantum dots (QDs), with sizes controlled with a high accuracy in the range from 1 to 10 nm.
