我们报告了远红外阻挡杂质带(BIB)探测器的成功制造。通过使用表面激活键合 (SAB) 技术键合两个分立的锗晶片,我们在吸收层和阻挡层之间形成了清晰的边界界面,过渡层厚度为 8 nm。结果,与传统的 Ge:Ga 光电导体探测器相比,在 2 K 下实现了约 7 A/W 的良好响应度,并具有更长的截止波长。
We report a successful fabrication of a far-infrared blocked-impurity-band (BIB) detector. We achieve a clear boundary interface between an absorption layer and a blocking layer with a transition layer of 8 nm thick by bonding two discrete germanium wafers using surface activated bonding (SAB) technique. As the results, a good responsivity of ~7 A/W at 2 K has been achieved with extended cutoff wavelength compared to a conventional Ge:Ga photoconductor detector.
