Descripción

General description

Atomic number of base material: 34 Selenium

Dimethyl selenide is a high-purity (≥99.0% by GC), volatile organoselenium compound in liquid form, primarily used as a catalyst and a precursor for solution and vapor deposition processes. Its excellent volatility and reactivity make it suitable for thin-film fabrication techniques such as chemical vapor deposition (CVD) and atomic layer deposition (ALD), particularly in the synthesis of semiconductor and optoelectronic materials.

Application

Dimethyl selenide can be used as:

• A precursor to prepare high-quality nanometric metal selenides, which are important for applications in thermoelectric, catalysis, and optoelectronics.
• A key reagent in the synthesis of tin(IV) methylselenolate complex, which is used as a precursor for SnSe and as a conductive interparticle "glue" for colloidal nanocrystals.
• A precursor to synthesize tin selenide (SnSe), which is used as a semiconductor with thermoelectric and electronic applications.

Features and Benefits

• High Purity (≥99.0% GC): Ensures consistency and reliability in sensitive chemical syntheses and deposition processes
• Volatile Liquid: Low boiling point and high vapor pressure make it ideal for vapor-phase processes like CVD and ALD
• Easy Handling
