- A Micro-pulse Process of Atomic Layer Deposition of Iron Oxide Using Ferrocene and Ozone Precursors and Ti-Doping
Xianglin Li, Ng Chin Fan and Hong Jin Fan

A micro-pulse ALD process is developed for fast deposition of Fe2O3 on both planar and high aspect ratio substrates (nanowires and AAO channels). By introducing TiO2 co-deposition, a linear growth rate can be maintained up to 600 cycles, corresponding to a thickness of 33 nm. A controllable Ti-doping into Fe2O3 films is achievable by adjusting the ALD cycle ratios of TiO2 and Fe2O3.

Al-doped ZnO (AZO) films are deposited by atomic layer deposition (ALD) on borosilicate glass and Si using diethylzinc and aluminum isopropoxide as Zn and Al precursors, respectively. The effects of Zn/Al ALD cycle ratio and the Al source temperature on the Al dopant concentration and resistivity of AZO films are investigated. The AZO films deposited at an Al source temperature of 120°C show the lowest resistivity.
- Molecular Hybrid Structures by Atomic Layer Deposition – Deposition of Alq3, Znq2 and Tiq4 (q = 8-hydroxyquinoline)

Thin films of metal quinolines based on 8-hydroxyquinoline (q) and aluminum (Alq3), zinc (Znq2), and titanium (possibly Tiq4) are deposited using ALD in the temperature range 85–200 °C. This demonstrates the ALD growth of structures based on weak Van der Waals forces. The Alq3 material proves stable towards exposure to water during deposition. Films of both Alq3 and Znq2 are significantly photoluminescent active.
- Influence of Subsurface Hybrid Material Growth on the Mechanical Properties of Atomic Layer Deposited Thin Films on Polymers

The mechanical properties of Al2O3 ALD coatings on polyamide 6 are examined by nano-indentation and flexure testing to determine the influence of a sub-surface hybrid layer formed during the ALD process. The results show the importance of the consideration of this hybrid layer on the use of these materials in future flexible electronic and encapsulation applications.
