Avalanche multiplication for quantum dot photodetectors with ultrahigh detectivity

Multiple exciton generation can increase the detectivity in photodetectors but has limited effect in infrared detectors. Now, a strategy for kinetically pumped avalanche multiplication has been demonstrated in colloidal quantum dot-based infrared photodetectors, achieving an 85-fold multiplication gain and ultrahigh detectivity of 1.4 × 1014 Jones.
