Mg2Si Single Crystal for Infrared Detectors
Summary
Mg2Si (magnesium silicide) single crystal is a semiconductor material that can detect a wide range of wavelengths, from visible light (VIS) to near infrared (NIR) and shortwave infrared (SWIR), and is expected to be used for various sensors.
Application Examples
- Industrial inspection cameras
(contamination, quality, crop evaluation, etc.) - Surveillance cameras
- Blood glucose level sensors
- LiDAR

Benefits for Customers
- IR sensors using InGaAs have high performance with high cost, but those using Mg2Si are expected to achieve a balance between performance and cost.
- Mg2Si is expected to have higher detection sensitivity (D*) than Ge.
- Mg2Si can detect a wider range of wavelengths extending to longer wavelengths than Si.
- Sensors using Mg2Si can enable simple device structures with a P/N junction fabricated by thermal diffusion.
Features of Mg2Si Single Crystal
- Mg2Si single crystal can be used as a single material to detect a wide range of wavelengths from visible light to near-infrared and shortwave infrared.
- Mg2Si can easily control carrier concentration and P/N type by thermal diffusion.
- The raw materials are readily available, and large, high quality single crystals can be expected to be grown.
- JX Metals is working with Ibaraki University to develop Mg2Si single crystals and reduce the cost of sensors and devices.
