从前我们曾报导,汞离子注入能使p型Hg_(1-x)Cd_xTe层转变成n型并用这种技术制得高质量光伏探测器,其截止波长范围从2到14微米。这些结果,加上资料[2]的那些报导,第一次表明用离子注入技术制备工作在77°K的8~14微米范围的二极管是可能的。另方面在比较短的波长中,离子注入和质子轰击已成功地制备出光伏红外探测器。这里,提出Hg~+离子注入Hg_(1-x)Cd_xTe光伏探测器最新的一些研究结果,特别着重介绍利用这种技术制备的多谱线组合器件。这样的器件允许同时接收光谱和空间信息而无需采用色散的光学系统,因此能简化多谱线遥感系统光学部份的复杂性。除此之外,还便于制造信道数目少的特殊目的系统。事实上,就地质、水文和农业这些地球资源勘探的某些方面而论,人们一般都知道
We have previously reported that mercury ion implantation converts the p-type Hg_ (1-x) Cd_xTe layer to n-type and uses this technique to produce high quality photovoltaic detectors with cutoff wavelengths ranging from 2 to 14 microns. These results, together with those reported in data [2], for the first time indicate that it is possible to prepare diodes operating in the range of 8 to 14 microns at 77K using ion implantation techniques. On the other hand, in the relatively short wavelength, ion implantation and proton bombardment have been successfully prepared photovoltaic infrared detector. Here, we present some newest research results of Hg ~ + ion implantation Hg_ (1-x) Cd_xTe photovoltaic detector, with special emphasis on the multi-spectral combination device prepared by this technique. Such a device allows the simultaneous reception of spectral and spatial information without the use of dispersive optical systems, thereby simplifying the optical part of the multi-spectral remote sensing system. In addition, it is easy to create special-purpose systems with a small number of channels. In fact, as far as certain aspects of the Earth's resources exploration, geology, hydrology and agriculture, are concerned, it is generally known
