Journal ArticleDOI
Three-Dimensional Writing of Highly Stretchable Organic Nanowires
TL;DR: In this article, 3D nanoarches of poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) with unprecedented stretchability, over 270%, and no compromise on the electrical characteristics were fabricated.
Journal ArticleDOI
Nucleation and Growth of the HfO2 Dielectric Layer for Graphene-Based Devices
Il Kwon Oh,Jukka T. Tanskanen,Hanearl Jung,Kangsik Kim,Mi Jin Lee,Zonghoon Lee,Seoung-Ki Lee,Jong Hyun Ahn,Chang Wan Lee,Kwanpyo Kim,Hyungjun Kim,Han-Bo-Ram Lee +11 more
TL;DR: In this article, the authors investigated nucleation and growth characteristics of atomic layer deposition (ALD) HfO2 on exfoliated and chemical vapor deposition (CVD) graphene by using two Hf precursors, tetrakis(dimethylamino)hafnium (TDMAH) and hafnium tetrachloride (HfCl4).
Journal ArticleDOI
Approaching ultimate flexible organic light-emitting diodes using a graphene anode
Tae Hee Han,Min-Ho Park,Sung Joo Kwon,Sang-Hoon Bae,Hong Kyu Seo,Himchan Cho,Jong Hyun Ahn,Tae-Woo Lee +7 more
TL;DR: Lee et al. as mentioned in this paper used an easily controlled and low-temperature processable charge generation layer with lithium nitride (Li3N), which simultaneously provided efficient stacking of EL units and enhanced compatibility of the flexible device on a thin plastic substrate.
Journal ArticleDOI
Dynamic spin injection into chemical vapor deposited graphene
Ajit K. Patra,Simranjeet Singh,Brett Barin,Young-Ze Lee,Jong Hyun Ahn,E. del Barco,Eduardo R. Mucciolo,Barbaros Özyilmaz +7 more
TL;DR: In this paper, the authors demonstrate dynamic spin injection into chemical vapor deposition (CVD) grown graphene by spin pumping from permalloy (Py) layers and demonstrate a strong enhancement of the Gilbert damping at the py/graphene interface.
Journal ArticleDOI
On‐Fabrication Solid‐State N‐Doping of Graphene by an Electron‐Transporting Metal Oxide Layer for Efficient Inverted Organic Solar Cells
Hobeom Kim,Jinwoo Byun,Sang-Hoon Bae,Towfiq Ahmed,Jian-Xin Zhu,Sung Joo Kwon,Yeongjun Lee,Sung-Yong Min,Christoph Wolf,Hong Kyu Seo,Jong Hyun Ahn,Tae-Woo Lee +11 more
TL;DR: Lee et al. as mentioned in this paper proposed a method to solve the problem of particle filtering in the context of nanotechnologies, which is similar to the one we are investigating in this paper.
