| 1 | Formation of sub-100-nm suspended nanowires with various materials using thermally adjusted electrospun nanofibers as templates显示文摘The air suspension and location specification properties of nanowires are crucial factors for optimizing nanowires in electronic devices and suppressing undesirable interactions with substrates.Although various strategies have been proposed to fabricate suspended nanowires,placing a nanowire in desired microstructures without material constraints or high-temperature processes remains a challenge.In this study,suspended nanowires were formed using a thermally aggregated electrospun polymer as a template.An elaborately designed microstructure enables an electrospun fiber template to be formed at the desired location during thermal treatment.Moreover,the desired thickness of the nanowires is easily controlled with the electrospun fiber templates,resulting in the parallel formation of suspended nanowires that are less than 100 nm thick.Furthermore,this approach facilitates the formation of suspended nanowires with various materials.This is accomplished by evaporating various materials onto the electrospun fiber template and by removing the template.Palladium,copper,tungsten oxide(WO3),and tin oxide nanowires are formed as examples to demonstrate the advantage of this approach in terms of nanowire material selection.Hydrogen(H2)and nitrogen dioxide(NO2)gas sensors comprising palladium and tungsten oxide,respectively,are demonstrated as exemplary devices of the proposed method. | Yongkeun Oh Dae-Sung Kwon Eunhwan Jo Yunsung Kang Sangjun Sim Jongbaeg Kim | 2023 | Microsystems & Nanoengineering2023，9，1： | 0 |
