InGaAs epitaxial wafer substrate PD Array photodetector arrays can be used for LiDAR

Short Description:

InGaAs epitaxial film refers to indium gallium arsenic (InGaAs) single crystal thin film material formed by epitaxial growth technology on a specific substrate. Common InGaAs epitaxial substrates are indium phosphide (InP) and gallium arsenide (GaAs). These substrate materials have good crystal quality and thermal stability, which can provide an excellent substrate for the growth of InGaAs epitaxial layers.
The PD Array (Photodetector Array) is an array of multiple photodetectors capable of detecting multiple optical signals simultaneously. The epitaxial sheet grown from MOCVD is mainly used in photodetection diodes, the absorption layer is composed of U-InGaAs, the background doping is <5E14, and the diffused Zn can be completed by the customer or Epihouse. The epitaxial tablets were analyzed by PL, XRD and ECV measurements.
