Gallium selenide Granules are a crucial III-VI compound semiconductor material, typically appearing as black or dark gray crystalline particles. They possess a moderate direct bandgap of approximately 1.8–2.0 eV, exhibit excellent responsivity across the visible to near-infrared spectrum, and demonstrate unique photoconductive and photorefractive properties. This chemically stable material serves as a key foundational component for fabricating infrared optoelectronic devices, photovoltaic materials, and nonlinear optical elements.
We offer a comprehensive range of high-purity Ga2Se3 Granules products. Our portfolio spans multiple purity grades from standard to ultra-high levels, catering to diverse requirements from fundamental research to high-end device fabrication. Multiple particle size specifications are available, supported by flexible, professional moisture-proof sealed packaging ranging from gram-level samples to kilogram-scale batches, ensuring reliable supply for your research and production needs.

Q1: What distinguishes Ga2Se3 from GaAs materials?
A1: They differ in composition and bandgap. Ga₂Se₃ is a selenide with a narrower bandgap, primarily used for infrared optoelectronics. GaAs is an arsenide with high electron mobility, serving as the mainstream material for high-frequency microwave and infrared lasers.
Q2: What are the primary advantages of this material?
A2: Direct bandgap and strong light absorption. It efficiently converts light energy into electrical signals or light emission, making it highly suitable for photodetectors and light-emitting devices.
Q3: What safety precautions should be taken during use?
A3: Selenides are toxic and require standardized handling. Avoid inhaling or ingesting dust. Wear protective equipment and operate in a well-ventilated area.
Q4: What is its price level?
A4: It is classified as a high-value specialty material. Due to the cost of selenium and the high-purity preparation process, its price exceeds that of common semiconductor materials. However, its performance remains irreplaceable in specific applications.
