Abstract: “Simple fabricating methods of nanostructures are required for solving many kinds of problems in the field of electronic engineering. The fabrication of novel and functional nanostructures is a promising way toward innovations: low power consuming devices, sensors with higher sensitivity, selectivity, as well as other novel functions. However, various researches are limited in costly, complex and time-consuming methods. We demonstrated a simple way to obtain nanogap electrodes using ordinary photolithographic techniques and electromigration, and its application as chemoresistive gas sensor based on gold nano-particles (AuNPs)-bridging.”

Keywords: nanogap electrodes, gold nanoparticles, electromigration, chemiresistors
