摘要：

For extrinsic photoconductors with gain in excess of unity there is a minimum response time determined by the background flux. Combining this concept with conventional D* arguments leads to D*max/τmin = λ hc η 4 qμP ε{lunate}ε{lunate}0t 1 2. This sensitivity bandwidth product has a value of 2 × 1018 cm Hz 1 2 W sec for extrinsic germanium for 12.5 microns. © 1969.
