Description

Indium Selenide is a compound semiconductor material with the chemical formula In2Se3. It is valued for its unique optoelectronic properties, including a tunable bandgap and high photoconductivity, which are critical for advanced technological applications. This material is essential for researchers and manufacturers in the fields of photovoltaics, thermoelectrics, and next-generation electronics. The compound is supplied under strict quality control to ensure batch-to-batch consistency for demanding industrial and R&D use.

Application

• Thin-Film Solar Cells: Used as a light-absorbing layer in copper indium gallium selenide (CIGS) photovoltaic devices.
• Phase-Change Memory (PCM): Explored for non-volatile memory applications due to its reversible amorphous-crystalline phase transition.
• Thermoelectric Materials: Incorporated into compounds to convert waste heat into electrical energy, benefiting from its low thermal conductivity.
• Photodetectors & Sensors: Serves as a sensitive material for infrared and visible light detection in imaging and sensing systems.
• Layered 2D Materials Research: A subject of study for novel electronic and spintronic devices due to its van der Waals layered structure.
• Lubricant Additive: Acts as a solid lubricant or coating component under high-temperature and vacuum conditions.

Quality Control

Our Indium Selenide is produced and handled under a strict quality management system. Each batch undergoes comprehensive analysis to verify chemical identity, purity, and physical properties. A Certificate of Analysis (COA) detailing lot-specific results is provided with every shipment. We support custom purity requirements and specifications for research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is moisture-sensitive (hygroscopic) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent oxidation and degradation.
