We report progress in the study of thick CZT strip detectors for 3-D imaging and spectroscopy and discuss two approaches to device design. Unlike double-sided strip detectors, these devices feature both row and column contacts implemented on the anode surface. This electron-only approach circumvents problems associated with poor hole transport in CZT that(More)
In this paper, we report progress in the study of thick single-sided charge-sharing cadmium zinc telluride (CZT) strip detector modules designed to perform gamma-ray spectroscopy and 3-D imaging. We report on continuing laboratory and simulation measurements of prototype detectors with 11/spl times/11 unit cells (15/spl times/l5/spl times/7.5 mm/sup 3/). We(More)
Simulation of the charge sharing properties of single-sided CZT strip detectors with small anode pads are presented. The effect of initial event size, carrier repulsion, diffusion, drift, trapping and detrapping are considered. These simulations indicate that such a detector with a 150 mum pitch will provide good charge sharing between neighboring pads.(More)
Patience and self-control are important non-cognitive skills that are associated with favorable educational, economic and social outcomes. This paper provides empirical evidence to inform discussions on possible educational interventions to make children more forward-looking or less present-biased, by putting forward a way to identify self-control problems(More)
