Preparation of ZnO Nanorod/Graphene/ZnO Nanorod Epitaxial Double Heterostructure for Piezoelectrical Nanogenerator by Using Preheating Hydrothermal Dong-Myeong Shin1, Seok Hee Kang2, Seongsu Kim3, Wanchul Seung3, Ermias Libnedengel Tsege1, Sang-Woo Kim3, Hyung Kook Kim1, Suck Won Hong2, Yoon-Hwae Hwang1 1Department of Nanoenergy Engineering, BK21 Plus Nanoconvergence Technology Division, Pusan National University (PNU), Miryang, 2Department of Cogno-Mechatronics Engineering, Pusan National University (PNU), Busan, 3SKKU Advanced Institute of Nanotechnology (SAINT), Center for Human Interface Nanotechnology (HINT), SKKU-Samsung Graphene Center, Sungkyunkwan University (SKKU) One-step fabrication method for obtaining freestanding epitaxial double heterostructure is presented. This approach could achieve ZnO coverage with a higher number density than that of the epitaxial single heterostructure, leading to a piezoelectric nanogenerator with an increased output electrical performance.
