Abstract: Based on the achievement of synthesis of ZnO nanowires in mass production, ZnO nanowires gas sensors were fabricated with microelectromechanical system technology and ethanol-sensing characteristics were investigated. The sensor exhibited high sensitivity and fast response to ethanol gas at a work temperature of 300 °C. Our results demonstrate the potential application of ZnO nanowires for fabricating highly sensitive gas sensors.

“…1-3 P-type doping of ZnO has recently been demonstrated in both bulk films 4,5 and nanowires, 6 opening the door for a variety of devices based on p-n junctions. Additionally, ZnO nanowires have shown promise in applications that include gas sensors, which take advantage of their high surface area to volume ratio, 7 and room-temperature spintronics, as the incorporation of transition metals has been shown to induce ferromagnetism in both bulk ZnO 8 and ZnO nanowires. 9,10 ZnO nanowires have also demonstrated amplified spontaneous emission 11 and room temperature UV lasing due to their high exciton binding energy.…”

“…According to literature, [21][22][23][24][25][26][27][28][29][30][31]33 ZnO interacted uniquely with VOCs bearing hydroxyl groups. Therefore, in this study, the behaviors of our ZnO nanoparticles were examined their responses to six compounds (methanol, ethanol, propanol, TCE, carbon tetrachloride (CCl4), and chloroform (CHCl3)) each injected at a volume of 1 μL into the static cell.…”

“…For instance, taking advantage of the catalytic behavior of ZnO, sensors have been developed for the detection of NOx, 17 alkanes, 18 ethers, 19 amines, [20][21][22] ketones, [23][24][25] aromatic volatile compounds, 26 and alcohols. [27][28][29][30][31] Unfortunately, these sensors are typically operated at temperatures above 250 C to trigger catalytic reactions that allow electronic sensing. The need for extreme sensing conditions and catalytically reactive molecules limits the application of these types of detection systems.…”

“…Zinc oxide is a well-known semiconductor material with a wide band gap (3.37 eV) and a large exciton binding energy (60 meV) at room temperature [1]. ZnO nanoparticles have been extensively studied over the past decades because of their fascinating electrical [2], mechanical [3], optical [4], and piezoelectric properties [5].…”
