InGaAs/InGaAsP/InP heterostructures for high-power photodetectors

A UTC photodetector based on InGaAs/InGaAsP/InP heterostructures grown by MOCVD is demonstrated. A model of the band diagram of the photodetector is proposed. Energy barriers that reduce the rate of hole removal from the absorbing layer are shown. A solution to reduce these barriers and increase the holes velocity is proposed. © 2022 IEEE.
