In our previous studies, we demonstrated a continuous current flow by filling a nanofluids consisting of dodecanethiol coated Au nanoparticles of 3-5 nm in diameter into an inter-electrode gap. Experiments showed that the gap thickness influences the performance of the device and theoretical analysis can relate this to interactions between the nanoparticles and strength variations of the electrical field. In this paper, we report on our efforts on design, fabrication, and evaluation of two types of gaps between metal electrodes of different work functions for the investigation of device performances as well as the operational mechanism. The merits, achievements, as well as process compatibilities of each design will be presented and discussed. The efforts and the results of this work may offer practice applicable nanomanufacturing approaches to fabricating submicron gaps for many other potential applications as well.本誌: 電気学会論文誌E（センサ・マイクロマシン部門誌） Vol.143 No.8 （2023）本誌掲載ページ: 225-230 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejsmas/143/8/143_225/_article/-char/ja/
