Sommario La popolazione urbana è in crescita costante: ogni anno aumenta di circa 60 milioni di persone, soprattutto nei Paesi a medio reddito. Proiezioni di popolazione mostrano che nei prossimi 30 anni la crescita globale avverrà solo nelle aree urbane. I cambiamenti demografici in corso (urbanizzazione, peggioramento degli stili di vita, invecchiamento della popolazione e isolamento sociale) si...
A cadmium sulfide (CdS) passivation process was demonstrated for the first time on InGaAs/InP p-i-n mesa photodetectors. The passivated devices produced lower reverse bias leakage currents in comparison to devices that received only a thermally deposited SiO2 film. The subsequent deposition of SiO2 on the passivated devices produced virtually no change to the aforementioned leakage currents even after...
