We used a superconducting nanowire single photon detector integrated with a current reservoir in a closed-cycle cryocooler to demonstrate RF-amplifier-free photon counting. By removing the RF ...

We describe a stacked detector made of thin CdTe diode detectors. By using a thin CdTe device, we can overcome the charge loss problem due to the small mobility and short lifetime of holes in CdTe or ...
