Noise and bandwidth
Johnson, generation-recombination, 1/f, bandwidth, and instrumentation contributions.
Technical scopeInfrared photodetector analysis
Electrical, spectral, and noise data are evaluated together for HgCdTe (MCT), InSb, and related infrared detectors.
Core capabilities
A detector can appear limited by the material, the device geometry, the operating point, or the test system. The full dataset is used to distinguish among them.
Johnson, generation-recombination, 1/f, bandwidth, and instrumentation contributions.
Technical scopeOperating regimes, gain behavior, saturation, heating, contacts, and current spreading.
Technical scopeCutoff, composition, thickness, response shape, and measurement artifacts.
Technical scopeReview method
The review checks the measurements, the test conditions, and the physical explanations before recommending additional work.
See the complete review processDevice geometry, temperature, bias, bandwidth, calibration, and instrumentation are established first.
Each proposed mechanism is checked against the observed scaling and known physical limits.
The next test is selected for its ability to distinguish the remaining explanations.
