SAFC Hitech Paper Success at EuroCVD18 Conference

October 3rd, 2011

Congratulations to SAFC Hitech Research Chemist Sarah Hindley who recently won first prize for the oral presentation of ‘Metal Organic Chemical Vapour Deposition of Vertically-Aligned ZnO Nanowires using Oxygen Adducts’ at the EuroCVD18 Conference, which took place in Kinsale, County Cork, Ireland from the 4th – 9th September 2011.

The presentation of a summary of an original paper, authored by Sarah and A. C. Jones, S. Ashraf, J. Bacsa, A. Steiner, P. R. Chalker, P. Beahan, P. A. Williams, R. Odedra, won Sarah a first prize of 300€.

The presentation looks at Zinc Nanowires and how better results can be achieved in terms of the severe pre-reaction (particulates, poor composition control, poor morphology) using conventional MOCVD methods by using new, less reactive ZnO precursors.  It then goes on to look at precursor (Me2Zn.L) design, structure and processing via Liquid Injection CVD.  The summary findings indicated that:

- Me2Zn.L allow ZnO nanowire growth on Si(111) substrates at ~500oC in the absence of a seed layer

- Me2Zn.L adducts controls initial reaction with O2 via the formation of a gas phase species [MeZn(OMe).(L)]

- MeZn(OMe) is the reactive surface species control ZnO nanowire growth kinetics

‘Strategies in Light’ Illuminating for SAFC Hitech

May 25th, 2011

In February of this year, SAFC Hitech Chief Technology Officer Ravi Kanjolia spoke at the Strategies in Light conference in Santa Clara as part of a session that sought to address manufacturing issues and strategies for LEDs, chaired by Solid State Technology’s Pete Singer.  The session examined some of the challenges facing the industry as it seeks to meet the demands of high volume LED production for use across an increasingly wide a variety of applications, including backlight illumination in flat panel displays and TVs, solid state and architectural lighting and so on.
