Siti Zulaikha Ngah Demon, school of Materials Science has received the student award in the 9th International Symposium on Atomic Level Characterizations for New Materials and Devices 2013(ALC'13)

Siti Zulaikha Ngah Demon, the third-doctoral student of the school of Materials Science(Mizutani Laboratory) has received the student award in the 9th International Symposium on Atomic Level Characterizations for New Materials and Devices 2013(ALC' 13) The symposia focus on practical applications of atomic level characterization (both atomic dimensions and energy levels) of new materials and devices, including bio- and organic materials as well as inorganic. The award is given by the 141st Committee on Microbeam Analysis of Japan Society for the Promotion of Science (JSPS) to participating students with outstanding contribution to the atomic level characterizations for new materials and devices.

[Prized title] Study of ITO/organic Interfaces by Second Harmonic Generation (SHG) Phase Measurement
[Abstract] We present a study of the interface dipoles of double layered structures of indium tin oxide (ITO)/organic semiconductor by second harmonic generation (SHG) phase measurement. The interfaces of organic films; CuPc, pentacene, -6T, 2-TNATA, m-MTDATA and NPD at the heterojunction of inorganic ITO were used to predict the general properties of the interface dipoles. Phase shift was measured directly from SHG interference patterns with translation of the second order nonlinear crystal, -SiO2 along the output beam path. Analysis of the absolute phase from the interface indicated the charge transfer complexes present at the interfaces of CuPc and pentacene. In the measurement of ITO/NPDs, we observed oscillation of the signal dependent on the thickness of the organic layer.
[Comment] I would like to thank the organizer of the ALC'13 for their recognition of my research work. My utmost gratitude goes to my main supervisor Prof. Dr. Goro Mizutani and former assistant professor of Mizutani laboratory, Dr. Yoshihiro Miyauchi for their enlightening guidance and patience in having me as a student. It is an exciting experience and a wonder working in Mizutani lab where I am able to get hands-on and practical skills in the field of nonlinear optics, something that I had only known in theory before I enrolled in JAIST. I would also like to thank my family and fellow friends for the emotional support during my study in Japan. The work will not be possible without our collaborator from Murata laboratory, Prof. Dr. Murata and Dr. Matsushima. I am very thankful to them. To me, it seems the work has just only begun and hopefully there will be more stimulating progress in near future.
