Dual-sided Charge-Coupled Devices

Understand

Existing Charge-Coupled Devices (CCDs) operate by detecting either the electrons or holes created in an ionization event.

• We propose a new type of imager, the Dual-Sided CCD, which collects and measures both charge carriers on opposite sides of the device via a novel dual-buried channel architecture.
• We show that this dual detection strategy provides exceptional dark-count rejection and enhanced timing capabilities.
• These advancements have wide-ranging implications for dark-matter searches, near-IR/optical spectroscopy, and time-domain X-ray astrophysics.
