Suyeon Cho,Sera Kim,Jung Ho Kim,Jiong Zhao,Jinbong Seok,Dong Hoon Keum,Jaeyoon Baik,Duk-Hyun Choe,Kee-Joo Chang,Kazu Suenaga,Sung Wng Kim,Young Hee Lee,Heejun Yang +12 more
TL;DR: Laser-induced phase patterning is used to fabricate an ohmic heterophase homojunction between semiconducting hexagonal and metallic monoclinic molybdenum ditelluride that is stable up to 300°C and increases the carrier mobility of the MoTe2 transistor by a factor of about 50, while retaining a high on/off current ratio of 106.
Journal ArticleDOI
Free-Standing Single-Atom-Thick Iron Membranes Suspended in Graphene Pores
Jiong Zhao,Qingming Deng,Alicja Bachmatiuk,Alicja Bachmatiuk,Gorantla Sandeep,Alexey A. Popov,Juergen Eckert,Juergen Eckert,Mark H. Rümmeli +8 more
TL;DR: A free-standing crystalline single-atom-thick layer of iron (Fe) is shown using in situ low-voltage aberration-corrected transmission electron microscopy and supporting image simulations to pave the way for new 2D structures to be formed in graphene membranes.
Journal ArticleDOI
A Growth Mechanism for Free-Standing Vertical Graphene
TL;DR: A continuum model based on the surface diffusion and moving boundary (mass flow) is developed to describe the intermediate states of the steps and the edges of graphene and the experimentally observed convergence tendency of the Steps near the top edge can be explained.
Journal ArticleDOI
Solution-Phase Epitaxial Growth of Perovskite Films on 2D Material Flakes for High-Performance Solar Cells.
Guanqi Tang,Peng You,Qidong Tai,Anneng Yang,Jiupeng Cao,Fangyuan Zheng,Zhiwen Zhou,Jiong Zhao,Paddy K. L. Chan,Feng Yan +9 more
TL;DR: In this article, a solution-phase van der Waals epitaxy growth of MAPbI3 perovskite films on MoS2 flakes is reported under transmission electron microscopy.
Journal ArticleDOI
Misorientation-angle-dependent electrical transport across molybdenum disulfide grain boundaries
Thuc Hue Ly,David J. Perello,Jiong Zhao,Qingming Deng,Hyun Kim,Gang Hee Han,Sang Hoon Chae,Hye Yun Jeong,Young Hee Lee +8 more
TL;DR: This work explores misorientation angle-dependent electrical transport at grain boundaries in monolayer MoS2 by correlating the atomic defect structures of measured devices analysed with transmission electron microscopy and first-principles calculations.
