The deposition of energy in large and small sensitive volumes is studied after ultrahigh energy heavy-ion irradiation. We demonstrate that the energy deposition increase effect previously reported in p-i-n diode detectors due to delta electrons occurs only in large sensitive volumes, but not in small ones, typical of advanced microelectronic devices, such as the cells of a 3-D NAND Flash memories. We attribute this effect to the trajectories of the secondary electrons.

Abstract
The deposition of energy in large and small sensitive volumes is studied after ultrahigh energy heavy-ion irradiation. We demonstrate that the energy deposition increase effect previously reported in p-i-n diode detectors due to delta electrons occurs only in large sensitive volumes, but not in small ones, typical of advanced microelectronic devices, such as the cells of a 3-D NAND Flash memories. We attribute this effect to the trajectories of the secondary electrons.File in questo prodotto:
