일반 설명

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.

애플리케이션

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.

ALD — A Versatile Tool for Nanostructuring

As the electronic industry continues to move towards smaller and smaller devices, researchers must continually strive for technologies to deposit electronic materials with precision at ever-smaller scales. This trend has lead to a variety of techniques used in the microelectronics industry to layer materials with precision thicknesses, sometimes down to even the atomic level.

Since the demonstration of the first practical solar cell 60 years ago, research on novel materials, improved solar cell design and structure, and innovative manufacturing processes have all contributed to a continuous increase in the efficiency of photovoltaic (PV) devices.

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