Below 1% Reflectance for Black GaAs Surface Prepared by Facile Two‐Step Wet Chemical Treatment: Hydrogen Peroxide and Water

open access: yesAdvanced Photonics Research, EarlyView.
Black GaAs surface which decreases light reflectivity forms in surprising way when GaAs is kept first in hot hydrogen peroxide solution and then in hot‐water solution. To increase performance of many photonic devices (e.g., solar cell, light emitting diode (LED), photodetector), it is essential to decrease light reflection at device interfaces ...

CMOS‐Compatible Short‐Wave Infrared Linear Arrays of Ge‐on‐Si Avalanche Photodiodes

open access: yesAdvanced Photonics Research, EarlyView.
The fabrication and characterization of a new type of surface‐illuminated Si‐based avalanche photodiode array operating in the short‐wave infrared region using germanium as the absorber and silicon as the multiplier is reported. The demonstration of an avalanche gain of 24 at a temperature of 378 K allows the devices to operate in outdoor environments.
