Abstract

NO2 gas sensing mechanism of IZO nanorods synthesized by low cost and simple reflux method.

Optimizing Gas Sensing Properties of Fe-Loaded Indium Zinc Oxide Nanocomposite for Efficient Detection of Ammonia Gas

“…It is detected that as the concentration of Indium and Iron are more, they subsequently increase the intensity of the (002) peak. 18 As we noticed hydroxyl of Zn(OH) 2 and In(OH) 3 in the XRD results and therefore we increased the drying temperature of the synthesized sample above 350 °C to 700 °C for 3 h so that these hydroxides can be eliminated and the sensing performance can be improved.…”

“…The E 2 optical phonon band at 437.8 cm −1 which is the fingerprint region of ZnO. 18 The optical phonon modes E 1 (TO) 407 cm −1 and A 1 (TO) 379 cm −1 contribute to a broad shoulder of the E 2 band, while around 592 and 574 cm −1 the E 1 (LO) and A 1 (LO) optical phonons.…”

Bio‐Inspired Artificial Perceptual Devices for Neuromorphic Computing and Gesture Recognition

“…[36] In addition, the diffraction peak intensity and crystal orientation of electrodeposited ZnO film are also affected by In 3+ substitution. [37] The pure ZnO film has sharper and intense major diffraction peaks, suggesting that it has a higher crystallinity. The decreased crystallinity of doped ZnO may be related to structural distortion and inner tensile stress caused by the introduction of In dopants.…”

P-type to N-type conversion of Fe-doped Cu2BaSnS4

“…29 In this work, an attempt has been made to increase the band gap of CBTS with the Fe dopant as Fe has partially filled d orbitals in an ionic state, which may tend to reduce the band tail states, thereby increasing the open circuit voltage and photoconversion efficiency. 30,31 Till now, no research work has been reported on Fe-doped CBTS, which increases the band gap and reduces the band tail risk and the Urbach energy.…”
