摘要：

The design, fabrication, and characterization of heterojunction photodiodes for room temperature operation in the mid-infrared (3-5 mu m) spectral range is described. Devices appropriate for carbon dioxide detection have been developed and studied. The authors report on the improvements obtained by increasing buffer layer thickness and also by using a blocking barrier to reduce leakage current. (c) 2006 American Institute of Physics.
