概要

• 論文の詳細を見る

• Devices based on the contact of sputtered WO_3 and IrO_2 that are covered by an HCO^-_3-containing polymer exhibit reversible and reproducible CO_2-dependent, diodelike current rectification at 1 atm and room temperature. The gain or loss of current in the forward direction as a function of CO_2 concentration is found to be tunable by controlling the thickness ratio of the WO_3 and IrO_2 films. The rectification mechanism is uniquely governed by the thermodynamic free energies; this is the key to the durability previously not attainable using conventional diodes in microsensor applications. These diodes are useful as a basis of construction for durable microsensors operating in gases or liquids.
