詳細

詳細

Trimethylaluminum (TMA) is a widely used precursor in the chemical vapor deposition (CVD) process to produce thin films in various applications. TMA is highly reactive and pyrophoric, which makes it an effective source of aluminum in thin film deposition processes to improve optoelectronic properties, such as enhanced light absorption and carrier transport characteristics.

アプリケーション

Trimethylaluminum can be used:

• As a growth initiator to synthesize self-assembled aluminum nanoparticles via atomic layer deposition.
• As a precursor to synthesize aluminum-doped ZnO thin films(AZO) for electron transport layer of perovskite solar cells. TMA enhances electrical conductivity and thermal stability of perovskite layers.
• To fabricate Al₂O₃-coated Si-alloy anodes for Li-ion batteries. This coating helps to suppress the volume expansion of Si and improves cell stability.
• To fabricate Al₂O₃-coated graphite electrode with superior anti-self-discharging behavior (260 h) with long stability (900 cycles), for Al-ion battery.

包装
