Current generation from radiation with diamond diode-based devices for detection or power generation
Patent
·
OSTI ID:1840261
Diamond diode-based devices are configured to convert radiation energy into electrical current, useable for sensing (i.e., detection) or delivery to a load (i.e., energy harvesting). A diode-based detector includes an intrinsic diamond layer arranged between p-type diamond and n-type diamond layers, with the detector further including at least one of (i) a boron containing layer arranged proximate to the n-type and/or the intrinsic diamond layers, or (ii) an intrinsic diamond layer thickness in a range of 10 nm to 300 microns. A diode-based detector may be operated in a non-forward biased state, with a circuit used to transmit a current pulse in a forward bias direction to reset a detection state of the detector. An energy harvesting device may include at least one p-i-n stack (including an intrinsic diamond layer between p-type diamond and n-type diamond layers), with a radioisotope source arranged proximate to the at least one p-i-n stack.
