一般描述

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.

应用

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

In recent years considerable interest in ALD has emerged, mainly due to its ability to controllably coat even very small structures, e.g. nanoor microstructures.

Continuous efficiency improvements in photovoltaic devices result from material advancements and manufacturing innovation.

The properties of many devices are limited by the intrinsic properties of the materials that compose them.

Nanomaterials are considered a route to the innovations required for large-scale implementation of renewable energy technologies in society to make our life sustainable.
