Experimental evaluation demonstrates single-electron photon counting in a double-gate floating surface detector, indicating viability for high-sensitivity imaging.

Key Points

Fabricate and characterize a novel on-chip charge detector for charge-coupled-device (CCD) area image sensors to achieve ultra-high sensitivity.
Fabricated a double-gate floating surface detector integrated on a CCD image sensor platform.
Evaluated detector performance across a 3.58-MHz video bandwidth at room temperature.
Assessed small-signal photon counting performance below 20 electrons by measuring discrete voltage levels on an oscilloscope.
Achieved a charge-to-voltage conversion gain of 220 µV/electron.
Demonstrated a noise equivalent electron level of 0.5 electrons r.m.s. with a dynamic range of 79 dB at room temperature.
Maintained high conversion gain in the small-signal region under 20 electrons, resolving discrete single-electron signal levels.
