InGaAs and other compound epitaxial wafers

High performance and high-quality compound semiconductor materials based on gallium arsenide (GaAs), indium phosphide (InP), and indium antimonide (GaSb) substrates can cover near-infrared to long wavelength infrared spectra, becoming a "golden band" solution in the field of optoelectronics. In the future, with breakthroughs in superlattice band engineering and heterogeneous integration technology, its applications will extend to cutting-edge fields such as quantum sensing and neural morphology computing.

Applications

Applied to photodetectors, avalanche diodes, heterojunction bipolar transistors, quantum cascade lasers, high electron mobility transistors, etc.

Features

InGaAs (Indium Gallium Arsenide) is a III-V compound semiconductor material with many superior properties, making it widely used in the fields of optoelectronics and semiconductors. Here are some of the main advantages of InGaAs materials:

Wide bandgap adjustment range: InGaAs can achieve wide bandgap adjustment by adjusting the composition of Indium and Gallium. This enables InGaAs to cover the infrared spectral range, including near-infrared and shortwave infrared, which is crucial for many optoelectronic devices and communication applications.

High electron mobility: InGaAs has a high electron mobility, making it an ideal choice for high-speed electronic devices. This is crucial for high-frequency, high-speed applications such as high-speed field-effect transistors (FETs) and high-frequency photodetectors.

Sensitivity of photodetectors: InGaAs has high photoelectric detection sensitivity in the near-infrared and shortwave infrared ranges. This makes InGaAs photodetectors widely used in fields such as night vision, communication, and medical imaging.

High saturation drift velocity: Due to its high electron mobility, InGaAs exhibits high saturation drift velocity under high electric fields. This is very advantageous for high-frequency applications and high-speed electronic devices.

Low noise performance: InGaAs photodetectors typically exhibit low noise levels, which is crucial for applications that require high detector sensitivity and accuracy, such as optical communications and scientific instruments.
