Journal ArticleDOI
Electrical manipulation of nanofilaments in transition-metal oxides for resistance-based memory.
Myoung-Jae Lee,Seungwu Han,Sang Ho Jeon,Bae Ho Park,Bo Soo Kang,Seung-Eon Ahn,Ki-Hwan Kim,Chang Bum Lee,Chang Jung Kim,In-Kyeong Yoo,David H. Seo,Xiang-Shu Li,Jong-Bong Park,Jung-Hyun Lee,Youngsoo Park +14 more
TL;DR: Through experiments on the negative resistance switching phenomenon in Pt-NiO-Pt structures, a nanofilament channels that can be electrically connected or disconnected are fabricated that are ideal for the basis for high-speed, high-density, nonvolatile memory applications.
Proceedings ArticleDOI
2-stack 1D-1R Cross-point Structure with Oxide Diodes as Switch Elements for High Density Resistance RAM Applications
Myoung-Jae Lee,Youngsoo Park,Bo Soo Kang,Seung-Eon Ahn,Chang-Bum Lee,Ki-Hwan Kim,Wenxu Xianyu,G. Stefanovich,Jung-Hyun Lee,Seok-Jae Chung,Yeon-hee Kim,Chang-Soo Lee,Jong-Bong Park,In-Kyeong Yoo +13 more
TL;DR: In this article, a 2-stack 8-times-8 array with 0.5 mumtimes0.5 cells was proposed to demonstrate the feasibility of high density stacked RRAM.
Journal ArticleDOI
High-Rate Capability Silicon Decorated Vertically Aligned Carbon Nanotubes for Li-Ion Batteries
Aurélien Gohier,Barbara Laïk,Ki-Hwan Kim,Jean-Luc Maurice,Jean-Pierre Pereira-Ramos,Costel Sorin Cojocaru,Pierre Tran Van +6 more
TL;DR: The concept of a hybrid nanostructured collector made of thin vertically aligned carbon nanotubes (CNTs) decorated with Si nanoparticles provides high power density anodes in lithium-ion batteries.
Journal ArticleDOI
Write Current Reduction in Transition Metal Oxide Based Resistance-Change Memory**
Seung-Eon Ahn,Myoung-Jae Lee,Youngsoo Park,Bo Soo Kang,Chang Bum Lee,Ki-Hwan Kim,Sunae Seo,Dongseok Suh,Dong-Chirl Kim,Ji-Hyun Hur,Wenxu Xianyu,G. Stefanovich,Huaxiang Yin,In-Kyeong Yoo,Jung-hyun Lee,Jong-Bong Park,In-Gyu Baek,Bae Ho Park +17 more
TL;DR: This work has focused on defining just the storage node portion of the devices, which utilize the resis-tance change within the film to store information via two dif-ferent stable resistance states, and has attempted to de-termine the properties of such structures.
Journal ArticleDOI
Acidic polysaccharide from Panax ginseng, ginsan, induces Th1 cell and macrophage cytokines and generates LAK cells in synergy with rIL-2.
Ki-Hwan Kim,Yun Sil Lee,In Sung Jung,Shin-Young Park,Hee Yong Chung,Ihn Rhan Lee,Yeon Sook Yun +6 more
TL;DR: It is demonstrated that ginsan generates LAK cells from both NK and T cells through endogeneously produced multiple cytokines, which may contribute to its effectiveness in the immunoprevention and immunotherapy of cancer.
