一般說明

三甲基铝(TMA)是在化学气相沉积(CVD)工艺中广泛应用的前体,用于生产各种应用中的薄膜。TMA具有高反应活性和自燃性,这些性质使其成为薄膜沉积过程中的有效铝源,可改善光电性质,如增强的光吸收和载流子传输特性。

應用

三甲基铝可用于:
  • 作为生长引发剂,通过原子层沉积合成自组装铝纳米颗粒。
  • 作为合成铝掺杂ZnO膜(AZO)的前体,用于钙钛矿太阳能电池的电子传输层。TMA增强钙钛矿层的电导率和热稳定性
  • 制备用于锂离子电池的Al2O3涂层硅合金阳极。这种涂层有助于抑制硅的体积膨胀,提高电池的稳定性。
  • 制备具有优异抗自放电性能(260小时)和长稳定性(900次循环)的Al2O3涂层石墨电极,用于铝离子电池。

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.

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.
