Journal ArticleDOI
Pinning effect on fluctuation conductivity in a superconducting untwinned YBa 2 Cu 3 O 7 − δ single crystal with columnar defects
Jin-Tae Kim,Yong-Ki Park,Jongnam Park,Hae-Ryong Lim,S. Y. Shim,D. H. Kim,Won Nam Kang,J. H. Park,Taek Sang Hahn,S.S. Choi,W. C. Lee,J. D. Hettinger,Kenneth E. Gray +12 more
TL;DR: The effect of columnar defects on the critical dynamics of a superconducting untwinned (YBCO) single crystal has been investigated in this article, where columnar defect is produced by Sn ion irradiation of which dose corresponds to a matching field of 1 T.
Journal ArticleDOI
Ninety Degree Domains in RF-Sputtered BaTiO3 Thin Films on Platinum Substrates
Jin Wook Jang,Woon Jo Cho,Jong-Ho Lee,In-Tae Kim,Young Hwan Kim,Changhoon Kim,J. H. Park,Sang Sam Choi,Taek Sang Hahn +8 more
TL;DR: In this paper, the formation of a 90° domain boundary was discussed in terms of planar defects such as the (111) twin and two kinds of stress relief mechanisms induced by 90° domains formation were proposed.
Journal ArticleDOI
Effect of heavy-ion irradiation on transport properties of YBa/sub 2/Cu/sub 3/O/sub x/ films
D. H. Kim,S. Y. Shim,J. H. Park,Young Hwan Kim,Changhoon Kim,Jin Wook Jang,Taek Sang Hahn,Sang Sam Choi,J. D. Hettinger,D.G. Steel,Kenneth E. Gray +10 more
TL;DR: In this paper, the effect of heavy-ion irradiation on the transport properties of YBa/sub 2/Cu/sub 3/O/sub x/ thin films was investigated.
Journal ArticleDOI
Digital and analog measurements of HTS SFQ RS flip-flops and shift register circuits
Young Hwan Kim,Joonhee Kang,Gun Yong Sung,J. H. Park,Jaeick Lee,K.R. Jung,Changhwan Kim,Taek Sang Hahn,S.S. Choi +8 more
TL;DR: In this paper, reset-set flip-flops and shift registers were fabricated using YBCO bicrystal junctions and tested using a computer-controlled digital measurement set-up and an analog measurement setup.
Journal ArticleDOI
Photoresponse of resistive and kinetic inductive YBa2Cu3Ox bolometer
S. Y. Shim,Dae Hwan Kim,Hae-Ryong Lim,J.S. Hwang,J. H. Park,Changhwan Kim,S.S. Choi,Taek Sang Hahn +7 more
TL;DR: In this paper, the authors used the same meander line made of YBa 2 Cu 3 O x thin film as a sensing element near the superconducting transition as a function of temperature and irradiation intensity.
