Adv. Opt. Mater. 2021, 18, 2001546 DOI: 10.1002/adom.202001546 In the originally published article, specific detectivity data was inaccurately calculated based on assumption of an ideal diode, which is not always valid. The photodetector by Equation (6) page 5. term r0 represents dynamic resistance. It should be obtained from derivative (dI/dV)−1 experimental I–V data. improper calculation leads to over- or under-estimation at below above around 200 K (Figure 4). corrected detectivities are now provided here, along with a short explanation changes that have been made. authors confirm these do affect conclusions article. abstract manuscript, next-to-last sentence read: correlation between background noise and sensitivity Te-hyperdoped Si photodiode, where maximum room-temperature found 1.1 × 109 cm Hz1/2 W−1 3.0 107 1.2 µm 1.55 µm, respectively.

Optically triggered infrared photodetector.

We demonstrate a new class of semiconductor device: the optically triggered infrared photodetector (OTIP). This photodetector is based on a new physical principle that allows the detection of infrared light to be switched ON and OFF by means of an external light. Our experimental device, fabricated using InAs/AlGaAs quantum-dot technology, demonstrates normal incidence infrared detection in the...

Quantum dot infrared photodetector enhanced by surface plasma wave excitation.

Up to a thirty-fold detectivity enhancement is achieved for an InAs quantum dot infrared photodetector (QDIP) by the excitation of surface plasma waves (SPWs) using a metal photonic crystal (MPC) integrated on top of the detector absorption region. The MPC is a 100 nm-thick gold film perforated with a 3.6 microm period square array of circular holes. A bare QDIP shows a bias-tunable broadband r...

Wavelength agile superlattice quantum dot infrared photodetector

A dual-band superlattice quantum dot infrared photodetector, providing bias-selectability of the response peaks, is demonstrated. The active region consists of two quantum dot superlattices separated by a graded barrier, enabling photocurrent generation only in one superlattice for a given bias polarity. Two response bands, one consisting of three peaks at 2.9, 3.2, and 4.9 m and the other cons...
