Hyun Kum,Hyungwoo Lee,Sungkyu Kim,S. Lindemann,Wei Kong,Kuan Qiao,Peng Chen,Julian Irwin,June Hyuk Lee,Saien Xie,Shruti Subramanian,Jaewoo Shim,Sang-Hoon Bae,Chanyeol Choi,Luigi Ranno,Seungju Seo,Sangho Lee,Jackson Bauer,Huashan Li,Kyusang Lee,Joshua A. Robinson,Caroline A. Ross,Darrell G. Schlom,Mark Rzchowski,Chang-Beom Eom,Jeehwan Kim +25 more
TL;DR: A universal mechanical exfoliation method of producing freestanding single-crystalline membranes made from a wide range of complex-oxide materials including perovskite, spinel and garnet crystal structures with varying crystallographic orientations is demonstrated.
Journal ArticleDOI
Oxygen environmental and passivation effects on molybdenum disulfide field effect transistors.
Woanseo Park,Juhun Park,Jingon Jang,Hyungwoo Lee,Hyunhak Jeong,Kyungjune Cho,Seunghun Hong,Takhee Lee +7 more
TL;DR: The study suggests that surface passivation is important for MoS(2)-based electronic devices and recommends that polymethyl methacrylate-passivated devices should be considered as a preferred material for FETs.
Journal ArticleDOI
Electron pairing without superconductivity
Guanglei Cheng,Michelle Tomczyk,Shicheng Lu,Joshua P. Veazey,Joshua P. Veazey,Mengchen Huang,Patrick Irvin,Sangwoo Ryu,Hyungwoo Lee,Chang-Beom Eom,C. Stephen Hellberg,Jeremy Levy +11 more
TL;DR: Cheng et al. as discussed by the authors showed that electron pairing in strontium titanate (SrTiO3) is stable at temperatures as high as 900 millikelvin, well above the superconducting transition temperature.
Journal ArticleDOI
Direct observation of a two-dimensional hole gas at oxide interfaces.
Hyungwoo Lee,Neil Campbell,Ja Kyung Lee,Thaddeus J. Asel,Tula R. Paudel,H. Zhou,Jung-Woo Lee,Brenton A. Noesges,Jung Woo T. Seo,Bumsu Park,Bumsu Park,Leonard J. Brillson,Sang Ho Oh,Evgeny Y. Tsymbal,Mark Rzchowski,Chang-Beom Eom +15 more
TL;DR: First-principles calculations, coherent Bragg rod analysis and depth-resolved cathodoluminescence spectroscopy consistently support the finding that to eliminate ionic point defects is key to realizing a 2DHG.
Journal ArticleDOI
Ambipolar Memory Devices Based on Reduced Graphene Oxide and Nanoparticles
TL;DR: This research presents a new approach called “superfunctional materials” which combines high-performance liquid chromatography with high-resolution 3D image analysis to solve the mystery of why superhigh-performance materials are attracted to each other.
