Journal ArticleDOI
van der Waals epitaxial growth of graphene on sapphire by chemical vapor deposition without a metal catalyst.
Jeonghyun Hwang,Moonkyung Kim,Dorr Campbell,Hussain Alsalman,Joon Young Kwak,Shriram Shivaraman,Arthur R. Woll,Arunima K. Singh,Richard G. Hennig,Sandeep Gorantla,Mark H. Rümmeli,Michael G. Spencer +11 more
TL;DR: Density functional theory calculations reveal that the binding between graphene and sapphire is dominated by weak dispersion interactions and indicate that the epitaxial relation as observed by GIXRD is due to preferential binding of small molecules on sappire during early stages of graphene formation.
Journal ArticleDOI
Electrical characteristics of multilayer MoS2 FET's with MoS2/graphene heterojunction contacts.
Joon Young Kwak,Jeonghyun Hwang,Brian Calderon,Hussain Alsalman,Nini Munoz,Brian Schutter,Michael G. Spencer +6 more
TL;DR: The electrical properties of multilayer MoS2/graphene heterojunction transistors are investigated and the charge transport mechanism in both junctions was determined to be either thermionic-field emission or field emission depending on bias voltage and temperature.
Journal ArticleDOI
Cellular Auxetic Structures for Mechanical Metamaterials: A Review.
Parth Uday Kelkar,Parth Uday Kelkar,Hyun Soo Kim,Hyun Soo Kim,Kyung Hoon Cho,Joon Young Kwak,Chong Yun Kang,Chong Yun Kang,Hyun Cheol Song +8 more
TL;DR: A review of cellular auxetic structures for mechanical metamaterials with a special emphasis on state-of-the-art applications of these structures in important domains such as sensors and actuators, the medical industry, and defense while touching upon ways to accelerate the material development process.
Journal ArticleDOI
A universal transfer route for graphene
Sandeep Gorantla,Alicja Bachmatiuk,Jeonghyun Hwang,Hussain Alsalman,Joon Young Kwak,Thomas Seyller,Jürgen Eckert,Michael G. Spencer,Mark H. Rümmeli +8 more
TL;DR: This paper presents a facile and cheap route that can be applied to graphene over any substrate that is based on a wet chemical reaction producing gaseous species which can intercalate between the substrate and the graphene and thus gently delaminate the two.
Journal ArticleDOI
Growth and Interlayer Engineering of 2D Layered Semiconductors for Future Electronics.
Chanwoo Song,Gichang Noh,Gichang Noh,Tae Soo Kim,Min Soo Kang,Hwayoung Song,Ayoung Ham,Min-kyung Jo,Min-kyung Jo,Seorin Cho,Hyun-Jun Chai,Seong Rae Cho,Kiwon Cho,Jeongwon Park,Seungwoo Song,Intek Song,Sunghwan Bang,Joon Young Kwak,Kibum Kang +18 more
TL;DR: This review describes the preparation method of layered materials and suggests interlayer engineering via intercalation as a method for the development of artificial crystal and inevitable factors that layered materials must face to be used as electronic applications will be introduced with possible solutions.
