Real time monitoring of ordering in pentacene films during growth by using in-situ infrared spectroscopy
Autor: Yunbog Kim, Dongryul Jeon
Publikováno v: Current Applied Physics. 17:972-975
By employing the in-situ Fourier transform infrared (FTIR) spectroscopy and curve-fitting, we studied the evolution in the ordering of vacuum-deposited pentacene films. In the FTIR spectra, the thin film and bulk phases appeared at 903.2 cm −1 and

Learning Characteristics and Tactics of a Scientifically Gifted Student with Economic Difficulty and Physical Disadvantage: A Case Study of 'Haneul' of Saturday Physics Class
Autor: Dongryul Jeon, Seong-Min Cho
Publikováno v: Journal of Gifted/Talented Education. 22:729-755
As an effort to understand alienated gifted students, we investigated learning characteristics and learning tactics of a scientifically gifted student with economic difficulty and physical disadvantage. The student we studied is attending the Saturda

Effect of the Surface Roughness of Electrode on the Charge Injection at the Pentacene/Electrode Interface
Autor: Wooyoung Kim, Dongryul Jeon
Publikováno v: Journal of the Korean Vacuum Society. 20:93-99
We investigated how the surface roughness of electrode affects the charge injection at the pentacene/Au interface. After depositing Au film on the Si substrate by sputtering, we annealed the sample to control the Au surface roughness. Pentacene and A

Inquiry of Advanced Scince for Science High School Teacher: Relationship between Diameter and Emission Wavelength of CdTe Quantum Dot
Autor: Dongryul Jeon, Eui-Young Kim
Publikováno v: School Science Journal. 4:19-26
Contrary to bulk material, quantum effect founded in extremely small crystals(range of nanometer). This feature comes from energy structure of nano-sized material(nano particle) has intermediated character between isolated atom and bulk material. Par

Guided Inquiry of Fractal Phenomenon for High School Students: Au-Al Fractal Surface Alloy Growth
Autor: S. T. Park, Dongryul Jeon
Publikováno v: School Science Journal. 3:111-117
Fractal is an interesting and important phenomenon which is widely found in nature. Contrary to its importance, fractal is introduced in secondary science textbooks by simple pictures of tree branches or snow crystal without proper explanation. Here

Instrumentation for Sound Interference and Diffraction Measurement
Autor: S. T. Park, Dongryul Jeon
Publikováno v: School Science Journal. 3:30-36
Sound interference and diffraction is an important part of wave phenomena. Compared to the experiment on the light interference and diffraction, sound experiment is not widely performed at high schools because of the cumbersome equipment. In this exp
