Doping against the native propensity of MoS2: degenerate hole doping by cation substitution.
Joonki Suh,Tae Eon Park,Der Yuh Lin,Deyi Fu,Joonsuk Park,Hee Joon Jung,Yabin Chen,Changhyun Ko,Chaun Jang,Yinghui Sun,Robert Sinclair,Joonyeon Chang,Sefaattin Tongay,Junqiao Wu,Junqiao Wu +14 more
TL;DR: Stable p-type conduction in MoS2 is demonstrated by substitutional niobium (Nb) doping, leading to a degenerate hole density of ∼ 3 × 10(19) cm(-3), and it is expected that the synthesis technique demonstrated here can be generally extended to other TMDs for doping against their native unipolar propensity.
Journal ArticleDOI
Skyrmion-electronics: writing, deleting, reading and processing magnetic skyrmions toward spintronic applications.
Xichao Zhang,Yan Zhou,Kyung Mee Song,Tae Eon Park,Jing Xia,Motohiko Ezawa,Xiaoxi Liu,Weisheng Zhao,Guoping Zhao,Seonghoon Woo +9 more
TL;DR: The field of magnetic skyrmions has been actively investigated across a wide range of topics during the last decades as discussed by the authors, including information storage, logic computing gates and non-conventional devices such as neuromorphic computing devices.
Journal ArticleDOI
Skyrmion-based artificial synapses for neuromorphic computing
Kyung Mee Song,Jaeseung Jeong,Biao Pan,Xichao Zhang,Jing Xia,Sun Kyung Cha,Tae Eon Park,Kwangsu Kim,Kwangsu Kim,Simone Finizio,Jörg Raabe,Joonyeon Chang,Joonyeon Chang,Yan Zhou,Weisheng Zhao,Wang Kang,Hyunsu Ju,Seonghoon Woo,Seonghoon Woo +18 more
TL;DR: In this article, the accumulation and dissipation of magnetic skyrmions in ferrimagnetic multilayers can be controlled with electrical pulses to represent the variations in the synaptic weights.
Journal ArticleDOI
Magnetic skyrmion artificial synapse for neuromorphic computing.
Kyung Mee Song,Jaeseung Jeong,Sun Kyung Cha,Tae Eon Park,Kwangsu Kim,Simone Finizio,Jörg Raabe,Joonyeon Chang,Hyunsu Ju,Seonghoon Woo +9 more
TL;DR: In this article, an electrically-operating skyrmion-based artificial synaptic device designed for neuromorphic computing was presented, where current-induced creation, motion, detection and deletion of skyrms in ferrimagnetic multilayers can be harnessed in a single device at room temperature to imitate the behaviors of biological synapses.
Journal ArticleDOI
Reconfiguring crystal and electronic structures of MoS2 by substitutional doping.
Joonki Suh,Teck Leong Tan,Weijie Zhao,Joonsuk Park,Der-Yuh Lin,Tae Eon Park,Jonghwan Kim,Chenhao Jin,Nihit Saigal,Sandip Ghosh,Zicong Marvin Wong,Zicong Marvin Wong,Yabin Chen,Feng Wang,Feng Wang,Wladek Walukiewicz,Wladek Walukiewicz,Goki Eda,Junqiao Wu,Junqiao Wu +19 more
TL;DR: The authors investigate the structural and electronic effects of Nb doping in MoS2 crystals, which induces a structural transformation from naturally occurring 2H stacking to 3R stacking and produces strong and broadband photoluminescence via the formation of exciton complexes tightly bound to neutral acceptors.
