Autor: Jae-Hyung Wi, Won Seok Han, Dae-Hyung Cho, Sang Dae Choi, Boo-Kyoung Kim, Ju-Yeoul Baek, Yong-Duck Chung, Woo-Jung Lee
Publikováno v: Materials Science in Semiconductor Processing. 81:48-53
Chemical bath deposition (CBD)-ZnS is used as a buffer layer for Cu(In,Ga)Se2 (CIGS) solar cell and then, plasma damage originated from the negative oxygen ions or neutral particles with high energy is regarded as an important issue during subsequent

Autor: Sang Dae Choi, Kyoung-Joon An, Min-Jun Choi, Ju-Yeoul Baek, Kwun-Bum Chung, O Dae Kwon
Publikováno v: Applied Science and Convergence Technology. 25:73-76
Multi-layer films of SiN x /SiO x /InSnO with anti-reflective effect were grown by new-concept plasma enhanced chemical vapor deposition system (PECVD) with hybrid plasma source (HPS). Anti-reflective effect of SiN x /SiO x /InSnO was investigated as

Annealing Effect of Magnetic Properties in NiO/Co/Cu/Co Spin-valve Thin Films with Nano-oxide Layer
Autor: Ky-Am Lee, Jin-Hyup Choi, Sang-Dae Choi, Ho-Wan Joo
Publikováno v: Journal of the Korean Magnetics Society. 14:29-32
Magnetic properties are investigated for spin valves of Si/SiO/Ta(3 nm)/NiO(60 nm)/Co(2.5 nm)/Cu(1.95 nm)/Co(4.5 nm)/NOL(t nm ; Nano Oxide layer)/Ta(3 nm) with annealing. The annealing effect of spin valves with NOL are shown larger MR ratios from 10

Magnetoresistance Effect of Ta/NiFe/Cu/Co Pseudo Spin Valve Structure
Autor: Jin-Hyup Choi, Sang-Dae Choi, Ky-Am Lee, Ho-Wan Joo
Publikováno v: Journal of the Korean Magnetics Society. 14:25-28
The dependence of sensitivity, MR ratio, coercivity (Hc) and switching fields as a function of thickness of each magnetic layers(Co, NiFe and Cu) were investigated in pseudo spin valves with a structure of Ta/NiFe/Cu/Co. As measured results dependenc

Study on the Specular Effect in NiO spin-valve Thin Films
Autor: Sang-Dae Choi, Ho-Wan Joo, Ky-Am Lee
Publikováno v: Journal of the Korean Magnetics Society. 12:231-234
Magnetic properties are investigated for top- and bottom-type spin valves of Si/SiO/NiO(60nm)/Co(2.5nm)/Cu(1.95nm)/Co(4.5nm)/NOL(t nm; Nano Oxide layer). The MR ratios of the bottom-type spin valves with NOL are larger than those of the top-type spin
