Development of Radiation Hardened Far IR Detector Arrays. Volume 2. Phase 3

摘要

A detector manufacturing method for the fabrication of radiation hardened detectors and detector arrays is presented. Different types of linear and area arrays were fabricated and measured. The best performance data are noise equivalent power = 5 times 10 to the minus 17th power W/sq rt Hz, and current responsivity = 6 A/W. These improvements compared to the results of Phase 2 are obtained without enhancing the low sensitivity of these devices to ionizing radiation, which remains an order of magnitude lower than that of conventional extrinsic photoconducting detectors. An upper limit of the crosstalk is calculated to be 5 percent.
