Dual-sided Charge-Coupled Devices

Existing Charge-Coupled Devices (CCDs) operate by detecting either theelectrons or holes created in an ionization event. We propose a new type ofimager, the Dual-Sided CCD, which collects and measures both charge carriers onopposite sides of the device via a novel dual-buried channel architecture. Weshow that this dual detection strategy provides exceptional dark-countrejection and enhanced timing capabilities. These advancements havewide-ranging implications for dark-matter searches, near-IR/opticalspectroscopy, and time-domain X-ray astrophysics.
