项目摘要
We have developed germanium BIB detector for future mid- and far-infrared astronomical missions. In order to obtain clear interface between blocking and IR active layers, we have tested two new methods, surface activated bonding (SAB) and molecular beam epitaxial (MBE) crystal growth. We have fabricated a germanium BIB detector with SAB technique bonding a pure wafer (carrier concentration <8x10^12/cc) and a highly doped wafer (Ga 10^16/cc) and found that that device had a typical I-V characteristic for BIB detector, extended cut-off wavelength, and reduction of dark current. We have also achieved a high-purity germanium crystal growth on a high doped wafer with MBE technique that have a carrier concentration low enough for a blocking layer in BIB detector (5x10^14/cc).
我们为未来的中红外天文任务开发了锗围兜探测器。为了获得阻塞和IR活性层之间的清晰界面,我们测试了两种新方法,即表面激活键合(SAB)和分子束外延(MBE)晶体生长。我们已经用SAB技术粘合了纯晶片(载体浓度<8x10^12/cc)和高度掺杂的晶片(GA 10^16/cc),并发现该设备具有bib探测器的典型I-V特征,扩展的截止波长和降低黑暗电流的典型I-V特征。我们还通过MBE技术在高掺杂晶片上实现了高纯晶晶晶体的生长,该技术的载体浓度足够低,足以在围嘴检测器(5x10^14/cc)中阻断层。
