Leakage current analysis of silicon diode with anode activated by furnace annealing or laser annealing using deep level transient spectroscopy

AIP Advances, 2020
Silicon P-i-N diodes with a p+ region in the anode—where boron atoms are implanted and activated with relatively low-temperature furnace annealing (FA) or high-temperature laser annealing (LA)—show a large difference between the leakage currents of the ...

Effect of Schottky barrier height on quantitative analysis of deep-levels in n-type GaN by deep-level transient spectroscopy

AIP Advances, 2021
Deep-level transient spectroscopy (DLTS) using Schottky barrier diodes (SBDs) is widely used for quantitative analysis of deep levels. This study focuses on the dependence of Schottky barrier height on apparent time constants and concentrations of ...

Proton-induced leakage current in CCDs [PDF]

SPIE Proceedings, 2003
The effect of different proton fluences on the performance of two E2V Technologies CCD47-20 devices was investigated with particular emphasis given to the analysis of 'random telegraph signal' (RTS) generation, bright pixel generation and induced changes in base dark current level.
