Journal ArticleDOI
V2O5 nanofibre sheet actuators
Gang Gu,Michael C. Schmid,Po-Wen Chiu,Andrew I. Minett,J. Fraysse,Gyu Tae Kim,Siegmar Roth,Mikhail Kozlov,Edgar Muñoz,Ray H. Baughman +9 more
TL;DR: It is shown that the V2O5 sheets provide high Young's modulus, high actuator-generated stress, andhigh actuator stroke at low applied voltage, which facilitates electrochemical charge injection and intercalation that causes the electromechanical actuation.
Journal ArticleDOI
Origin of the slow photoresponse in an individual sol-gel synthesized ZnO nanowire
Seung-Eon Ahn,Seung-Eon Ahn,Hyunjin Ji,Kanghyun Kim,Gyu Tae Kim,Chang Hyun Bae,Seung Min Park,Yong Kwan Kim,Jeong Sook Ha +8 more
TL;DR: In this article, the photocurrent of a single ZnO nanowire synthesized by a sol-gel route was investigated, and it was shown that the photoresponse was slower than that in air, attributed to the release of the available charge carriers by desorption of water molecules and the decrease of the exchange rates of molecular ions.
Journal ArticleDOI
Growth and electrical transport of germanium nanowires
Gang Gu,Marko Burghard,Gyu Tae Kim,G. S. Düsberg,Po-Wen Chiu,Vojislav Krstić,S. Roth,Wei-Qiang Han +7 more
TL;DR: In this paper, single crystalline germanium nanowires were synthesized from gold nanoparticles based on a vapor-liquid-solid growth mechanism using argon as a carrier gas.
Journal ArticleDOI
Low-frequency noise in multilayer MoS2 field-effect transistors: the effect of high-k passivation
Junhong Na,Min-Kyu Joo,Min-Kyu Joo,Minju Shin,Minju Shin,Junghwan Huh,Jae Sung Kim,Mingxing Piao,Jun Eon Jin,Ho Kyun Jang,Hyung Jong Choi,Joon Hyung Shim,Gyu Tae Kim +12 more
TL;DR: Low-frequency noise in mechanically exfoliated multilayer molybdenum disulfide (MoS2) field-effect transistors with back-gate control was characterized with and without an Al2O3 high-k passivation layer, ensuring the existence of the bulk conduction in multilayers MoS2.
Journal ArticleDOI
A skin-integrated transparent and stretchable strain sensor with interactive color-changing electrochromic displays.
Heun Park,Dong Sik Kim,Soo Yeong Hong,Chul Min Kim,Junyeong Yun,Seung Yun Oh,Sang Woo Jin,Yu Ra Jeong,Gyu Tae Kim,Jeong Sook Ha +9 more
TL;DR: A stretchable, transparent, and skin-attachable strain sensor integrated with a flexible electrochromic device as a human skin-inspired interactive color-changing system that demonstrates high potential for use in interactive wearable devices, military applications, and smart robots.
