Journal ArticleDOI
Self-selective van der Waals heterostructures for large scale memory array.
Linfeng Sun,Yishu Zhang,Gyeongtak Han,Geunwoo Hwang,Jinbao Jiang,Bomin Joo,Kenji Watanabe,Takashi Taniguchi,Young-Min Kim,Woo Jong Yu,Bai-Sun Kong,Rong Zhao,Heejun Yang +12 more
TL;DR: A self-selective memory design able to combine, in the same cell, non-volatile and volatile behaviors with negligible sneak current is proposed, thereby achieving a practical readout margin for terabit-scale and energy-efficient memory integration.
Journal ArticleDOI
Layer-controlled single-crystalline graphene film with stacking order via Cu–Si alloy formation
Van Luan Nguyen,Dinh Loc Duong,Sanghyub Lee,José Avila,Gyeongtak Han,Young-Min Kim,Maria C. Asensio,Se-Young Jeong,Young Hee Lee +8 more
TL;DR: An approach for controlling the layer thickness and crystallographic stacking sequence of multilayer graphene films at the wafer scale via Cu–Si alloy formation using direct chemical vapour deposition is proposed.
Journal ArticleDOI
Tunable Negative Differential Resistance in van der Waals Heterostructures at Room Temperature by Tailoring the Interface.
Sidi Fan,Quoc An Vu,Sanghyub Lee,Thanh Luan Phan,Gyeongtak Han,Young-Min Kim,Woo Jong Yu,Young Hee Lee +7 more
TL;DR: It is demonstrated that heterointerface control is one of keys to achieving high device performance by constructing WSe2/SnSe2 heterostructures in inert gas environments and that diode behavior can be further modulated by controlling the electrostatic doping and the tunneling barrier as well.
Journal ArticleDOI
Monodispersed SnS nanoparticles anchored on carbon nanotubes for high-retention sodium-ion batteries
Thi Hoai Thuong Luu,Dinh Loc Duong,Tae Hoon Lee,Duy Tho Pham,Ramkrishna Sahoo,Gyeongtak Han,Young-Min Kim,Young Hee Lee +7 more
TL;DR: In this article, the authors proposed an effective approach to alleviate the volume pulverization and enhance the capacity of SIB anodes by anchoring SnS nanoparticles densely on a porous carbon nanotube (CNT) film (SnS@CNT).
Journal ArticleDOI
Ultralow switching voltage slope based on two-dimensional materials for integrated memory and neuromorphic applications
Linfeng Sun,Genuwoo Hwang,Wooseon Choi,Gyeongtak Han,Yishu Zhang,Jinbao Jiang,Shoujun Zheng,Kenji Watanabe,Takashi Taniguchi,Mali Zhao,Rong Zhao,Young-Min Kim,Heejun Yang +12 more
TL;DR: In this paper, a threshold switching device based on a vertical heterojunction of silver/hexagonal boron nitride (h-BN)/graphene was proposed.
