Abstract

Blocked impurity band(BIB)detectors are the state-of-the-art choice for far infrared astronomical ob-servation. Ge: B BIB far infrared detector has been successfully developed using near-surface processing tech-niques. The spectral response covers a wide range from 50 cm^-1 to 400 cm^-1. At a temperature of 3. 5 K and a working voltage of 30 mV, the detector exhibits a highly competitive responsivity of 21. 46 A∙W^-1 and a highly competitive detectivity of 4. 34×10¹⁴ cm∙Hz^1/2∙W^-1 at the peak response of 84. 9 cm^-1. The influence of the interfacial barriers on the spectral response is investigated. A new excitation model that the carriers in the contact regions can be excited over the interfacial barriers is proposed. Moreover, a new method to enhance the relative response intensity of BIB detectors in the low wavenumber region is found.
