Periodic boundary conditions were used to determine the bulk electronic and optical properties of the metal oxide thin film.…”

“…Observed reflectivity changes as a result of plasmon oscillations have been demonstrated in ITO by FTIR and SPR spectroscopy. 23,47,48 Therefore, similar investigations are warranted in AZO. In addition, studies of SAM formation on conducting metal oxides have also been previously described in the literature for TCOs such as ITO and CTO.…”

“…In addition, studies of SAM formation on conducting metal oxides have also been previously described in the literature for TCOs such as ITO and CTO. 22,47 Herein, we report the deposition of n-hexadecanethiol-and n-octadecanethiol-based SAMs onto the surface of a 2% aluminum-doped zinc oxide thin film. Reflectance infrared spectroscopy, X-ray photoelectron spectroscopy (XPS), contact angle, and near-edge X-ray fine structure spectroscopy (NEXAFS) are used to characterize SAM formation.…”

The optical and electronic properties of aluminum-doped zinc oxide (AZO) thin films on a glass substrate are investigated experimentally and theoretically. Optical studies with coupling in the Kretschmann configuration reveal an angle-dependent plasma frequency in the mid-IR for p-polarized radiation, suggestive of the detection of a Drude plasma frequency. These studies are complemented by oxygen depletion density functional theory studies for the calculation of the charge carrier concentration and plasma frequency for bulk AZO. In addition, we report on the optical and physical properties of thin film adlayers of n-hexadecanethiol (HDT) and n-octadecanethiol (ODT) self-assembled monolayers (SAMs) on AZO surfaces using reflectance FTIR spectroscopy, X-ray photoelectron spectroscopy (XPS), contact angle, and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. Our characterization of the SAM deposition onto the AZO thin film reveals a range of possible applications for this conducting metal oxide.

“…This can be compared with the lithography process on molecular level [12,13]. Chemisorbed thiols organized on the surface of transparent semiconductors, like ITO or cadmium-tin oxide, modify profoundly the optical properties of such materials, which is applied in the construction of optical nanodevices [14]. Commonly thiols are x-functionalized, i.e.…”

Hydrothermal synthesis and infrared emissivity property of flower-like SnO2 particles

The flower-like SnO2 particles are synthesized through a simple hydrothermal process. The microstructure, morphology and the infrared emissivity property of the as-prepared products are characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM), and infrared spectroradio meter (ISM) respectively. The results show that the as-prepared SnO2 products are all indexed to tetragonal cassiterite phase of SnO2. The different molarity ratios of the OH− concentration to Sn4+ concentration ([OH−]:[Sn4+]) and the polyacrylamide (PAM) lead to the different morphological structures of SnO2, which indicates that both the [OH−]:[Sn4+] and the PAM play an important role in the morphological evolution respectively. The infrared emissivities of the as-prepared SnO2 products are discussed.
