Structural characterization of indium oxide nanostructures: a Raman analysis

Abstract

In this work we report on structural and Raman spectroscopy measurements of pure and Sn-doped In 2 O 3 nanowires. Both samples were found to be cubic and high quality single crystals. Raman analysis was performed to obtain the phonon modes of the nanowires and to confirm the compositional and structural information given by structural characterization. Cubic-like phonon modes were detected in both samples and their distinct phase was evidenced by the presence of tin doping. As a consequence, disorder effects were detected evidenced by the break of the Raman selection rules.

Effect of Layer Thickness on I-V Characteristics of GaInP Nanofibers Fabricated by Electrospinning on n-Si Substrates

“…Figure 5 shows the XRD patterns of pure GaInP (black), of gallium indium oxide (red), indium oxide (blue) and gallium phosphate (green), which suggest that our film is polycrystalline. The results are in a good agreement with literature [20][21][22].…”

Influence of post-annealing on the structure and optical properties of ITO nanocrystals prepared by electrochemical method

“…The broad peak at 570 cm À1 is obviously resulted from the glass substrate. From above analysis, we can see that the phonon modes at 115, 137, 309, 369 and 499 cm À1 definitely come from cubic In 2 O 3 , which is in agreement with the reported values in the literatures [36,37]. The peak at 137 cm À1 is assigned to the In-O vibration of InO 6 structure units, and that at 309 cm À1 to the bending vibration of d(InO 6 ) octahedrons, while the peak at 499 cm À1 is attributed to the stretching vibrations of the same n(InO 6 ) octahedrons, whereas that at 369 cm À1 is assigned to the stretching vibrations of the In-O-In.…”

Effect of iron doping on structural, optical and electrical properties of sprayed In2O3 thin films

“…3. We observe two vibrational modes at 134 and 307 cm À1 for undoped indium oxide thin films which correspond to the modes of body centered cubic structure [22]. After doping, five other vibrational modes have been appeared at 109, 290, 338, 366 and 499 cm À1 .…”
