Fabrication of Low-Power Consumption Hydrogen Sensor Based on TiO_x/Pt Nanocontacts via Local Atom Migration by Yasuhisa Naitoh, Hisashi Shima, Hiroyuki Akinaga

“…The key findings are summarized as follows: (1) Resistive random-access memory (ReRAM) technology was used to fabricate extremely compact H₂ sensors via various forming techniques, and substantial sensor performance enhancement was investigated. (2) A nanocontact composed of titanium oxide (TiO_x)/platinum (Pt) was subjected to various forming operations to establish a Schottky junction with a nanogap structure on a tantalum oxide (Ta₂O₅) layer, and its properties were assessed. (3) When the Pt electrode was on the positive side during the forming operation used for ReRAM technology, a Pt nanopillar structure was produced. …”
