10.6-Micron (Hg,Cd)Te Photodiode Module.
Abstract
This report describes the development of a 10.6-micrometers (Hg,Cd)Te thermoelectrically cooled photodiode module operating at 174 K. The objective of the program was the demonstration of 170 K operation with quantum efficiency of 20 percent bandwidth of 50 MHz and a 1 mA reverse saturation current in a .0005 sq.cm. area device. Several approaches were assessed in order to achieve a heavily doped junction that would minimize diffusion current at 170 K. Two 10.6-micrometers (Hg,Cd)Te Photodiode Modules, each consisting of a n-on-p diffused (Hg,Cd)Te diode with an active area of .0002 sq.cm. mounted on a 6-stage thermoelectric cooler, were delivered. The better device had a minimum detectable power of 7.7 x 10 to the -19th power W/Hz, 23 MHz bandwidth, and 8.8 mA saturation current at 174 K. The power consumption for the module was less than 20 watts. (Author)
