Prof. Choi Seong Soo
SunMoon University, South Korea
Professor Seong Soo Choi graduated from Department of Physics, Seoul National University, 1973, received Ph.D. in Physics, at Department of Physics, University of North Carolina at Chapel Hill in May 1987. Then, he worked as research associate at Physics Department, North Carolina State University. I studied As impurity redistribution phenomena dependent upon the temperature under thermal oxidation during the PhD. Candidate period. During the period of (1987~ 1991., the native oxide and the surface studies on the II-VI surface were carefully examined to publish oxidation kinetics of native oxide formation of ( CdO + TeO2 ) on CdTe II-VI complex pound semiconductor, rather than TeO2 only on CdTe. Professor Choi’s group at SunMoon University also developed the cantilever array of atomic force microscope under coorperation with Professor Kuk in Seoul National University in 1996, first in Korea, then also developed the 100 nm diameter optical aperture on the cantilever for nearfield optical microscope (NSOM) in 1999. In year 2005, the diameter of 50 nm on Au coated pyramidal cantilever was successfully fabricated, then 5 nm diameter Au pore was fabricated by using electron beam irradiation. Recently, Professor Choi also found the kinetics of Au diffusion under electron beam irradiation; Au atoms always diffuse along with carbon atoms, later the formed Au- C membrane forms Au particles on the membrane due to Ostwald ripening and Spinodal decomposition. These observation can be valuable information to develop plasmonic nanopore on the Au for single molecule analysis. These observation can be valuable information to develop plasmonic nanopore on the Au for single molecule analysis. More recently, Professor Choi developed “self –cooling nano-silica pyramid system embedded in the crystalline silicon solar cell.” In this conference, fabrication of the self-cooling nanosystem will be addressed. In addition, he was a visiting research scientist at CNRS-LAAS, Toulouse, France in 2000, and also a visiting research professor at University of California at Berkeley, Ca, USA in 2010.

"Prediction of Hardening Depth for AISI 1045 Specimen by High-Frequency Induction Process with Finite Element Analysis"
Abstract: A high-frequency induction hardening analysis method was established based on electromagnetic-thermal translate analysis (co-simulation). To apply the same conditions as that of the experiment to the high-frequency induction hardening analysis, the temperature-dependent material properties of AISI 1045 were entered. During cooling, the analysis results could be obtained by setting the cooling conditions of water. After the hardening depth of the high-frequency induction-hardened specimen was measured using a micro Vickers hardness tester, the hardening depth and hardening pattern were verified with a metallurgical structure. The experiment results were compared with the finite element analysis (FEA) results. The hardening pattern could be confirmed because AISI 1045 was heated to over 746°C, which was the A2 transformation point, and cooled to below 200°C. The FEA results could confirm the heating and cooling temperatures. In addition, the hardening depth was found to be similar to the hardened area. When AISI 1045 was heated over the A2 transformation point, its structure transformed from ferrite to austenite and it changed from a magnetic material to a non-magnetic material. The FEA of magnetic flux density and Joule heat density during heating revealed that high-frequency induction hardening is favorable for surface hardening.
