Description

Triethylarsine is a highly reactive organoarsenic compound primarily utilized as a key precursor in advanced material synthesis. Its value lies in its ability to act as an efficient source of arsenic in the controlled deposition of semiconductor thin films, which is critical for modern electronics. This product is essential for manufacturers and R&D facilities in the semiconductor, photovoltaic, and specialty chemical industries seeking high-purity materials for vapor deposition processes.

Application

• Metalorganic Chemical Vapor Deposition (MOCVD): A crucial arsenic source for the epitaxial growth of III-V semiconductor compounds like gallium arsenide (GaAs) and indium arsenide (InAs).
• Thin-Film Photovoltaics: Used in the production of high-efficiency solar cells based on compound semiconductor materials.
• Light-Emitting Diodes (LEDs): Enables the fabrication of specific LED structures requiring arsenic-containing layers.
• Specialty Catalyst Synthesis: Serves as a ligand or precursor in the development of novel organometallic catalysts for research applications.
• Chemical Vapor Deposition (CVD): Employed in other CVD techniques for depositing arsenic-containing coatings and nanomaterials.
• Academic and Industrial Research: A fundamental reagent for exploring new organoarsenic chemistry and advanced material properties.

Quality Control

Our Triethylarsine is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and high purity, which is paramount for sensitive deposition processes. Each lot is analyzed to meet exacting specifications for electronic-grade applications. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profiles, and physical properties is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, store under an inert atmosphere (argon or nitrogen) in a cool, well-ventilated place. Recommended storage temperature is 2-8°C to minimize degradation and maintain stability. Keep away from heat, sparks, open flames, and oxidizing agents.
