Description

Dimethylethylindium is a high-purity organometallic compound, specifically a trialkylindium, widely used as a precursor in advanced material synthesis. Its primary value lies in enabling the precise deposition of indium-containing thin films, which are critical for high-performance electronic and optoelectronic devices. This material is essential for manufacturers and R&D facilities in the semiconductor, compound semiconductor, and photovoltaics industries seeking reliable, high-quality metalorganic sources for processes like Metalorganic Chemical Vapor Deposition (MOCVD) and Atomic Layer Deposition (ALD).

Application

• Precursor for the MOCVD growth of indium phosphide (InP) and related III-V compound semiconductors.
• Source material for the ALD deposition of indium oxide (In2O3) and indium tin oxide (ITO) transparent conductive films.
• Key reactant in the synthesis of specialized indium-containing nanomaterials and quantum dots.
• Used in research and development of next-generation photovoltaic cells, including CIGS (Copper Indium Gallium Selenide) thin-film solar cells.
• Employed in the fabrication of high-electron-mobility transistors (HEMTs) and other advanced microelectronic components.
• Facilitates the production of light-emitting diodes (LEDs) and laser diodes operating in specific wavelength ranges.

Quality Control

Our Dimethylethylindium is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and ultra-high purity, which is paramount for sensitive deposition processes. Each lot undergoes comprehensive analysis, including Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for metallic impurities and Gas Chromatography (GC) for organic purity and solvent residues. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, this product must be stored under a dry, oxygen-free inert gas (argon or nitrogen) in a cool, well-ventilated area. Recommended storage temperature is between 2°C and 8°C to maintain stability and minimize decomposition. Keep away from heat, sparks, open flames, and incompatible materials.
