Description
We present a novel, blue-sky detector concept that aims to replace the relatively slow process of charge-drift in a semiconductor with light-collection from scintillating quantum dots (QDs) in order to achieve ultimate timing performance in a thin, low-mass material for future charged-particle detectors. Here we show measured detection performance using self-assembling InAs QDs inside of a 25 micron thickness GaAs semiconductor matrix grown via molecular beam epitaxy with an InGaAs photodiode monolithcally integrated for efficient light collection. We will discuss the current performance in light-collection and energy resolution relative to the theoretical optimum performance. Finally, we will outline proposed future research directions to investigate significant improvements in detector performance, ultimately approaching fundamental limits.
