Profile: Giang Dang – Postdoctoral Fellow

MESA Chairperson Brendan Darby had a chat with a couple of students at different stages of their careers.  Meet postdocoral fellow, Giang Dang. Giang Dang  Postdoc Felow Can you give a brief overview of your journey to New Zealand in science? I was born in Vietnam, and went to Russia to take my specialist degree, where the diploma is 5 ½ years. I specialised in physics and in particular semiconductor physics. I then went to Japan to do my PhD in Applied Physics and graduated in 2011. In 2012 I got a PDF [postdoctoral fellowship] in Canterbury where I have been until now. Why did you decide to come to New Zealand to do a postdoc? My wife was doing her PhD here. And the position in Canterbury was very close to my PhD topic, studying oxide semiconductors with Martin Allen and Roger Reeves. Do you find the MacDiarmid Institute has helped with realising the goals of commercialising your research? Yes. When I first arrived, I managed to make some good quality transistors using a new class of oxide semiconductors (InGaZnO). Martin was then able to attract industry members through KiwiNet. We are working quite intensively recently to commercialise these transistors for use in displays such as TV screens and touch screens. The MacDiarmid Institute support came from the equipment; the entire cleaning room and all the equipment within is funded by the Institute. I was also awarded funding from the institute to travel back to Japan to use a growth technique called Mist Chemical Vapour Deposition (Mist-CVD) not available here in New Zealand. What are your plans for the future? I am currently applying for a grant to build up a Mist-CVD system to grow oxide-thin films. It is unique because you don’t need a vacuum chamber, and consequently is cheap but the quality of thin films is still very high. This would be a great technique for New Zealand to have. Any final words? I also love playing soccer—we play in the official division of Christchurch but it’s more precious for people to enjoy the game rather than the results. That’s what I love about the country and the people.
