Abstract

Synthesis of Nb2O5 thin films from sputter deposited Nb films and its optical property.

Voltage-Dependent Barrier Height of Electron Transport through Iron Porphyrin Molecular Junctions

“…The Raman analysis results indicated that FeP molecules were successfully deposited on the Au substrates. All vibrational modes were consistent within approximately 10 cm –1 to assignments reported in the literature. , AFM characterization of the bare Au substrate and the FeP self-assembled samples revealed a surface modification that supports the deposition of FeP on the Au substrate. See the Supporting Information for the analysis of the Raman spectra and AFM characterization of the images and surface morphology from FeP.…”

Early Transition Metal Doped Tungstite as an Effective Catalyst for Glucose Upgrading to 5-Hydroxymethylfurfural

“…Deconvolution of the peaks related to the dopants (Nb 3d and Ti 2p) yielded a single doublet for either material. Binding energies for the Nb 3d 5/2 and Ti 2p 3/2 components were 207.6 and 459.2 eV and were assigned to the fully oxidated states (Nb V and Ti IV ) [36,37]. Of note is that the amount of W V species differs from material to material.…”

Enhanced Coloration for Hybrid Niobium-Based Electrochromic Devices

“…10,11 . Niobium element characterized by several valence states from +2 to +4 to +5 for NbO, NbO2 and Nb2O5, respectively 12 , exists in various oxides polymorphic forms including monoclinic (H-Nb2O5), tetragonal (M-Nb2O5), orthorhombic (T-Nb2O5), and pseudo hexagonal (TT-Nb2O5). The different crystal phases of Nb2O5 depend on the synthesis temperature.…”

“…7,8 Since the discovery of electrochromism in Nb 2 O 5 in 1980, by Reichman and Bard, 9 niobium oxide has been studied extensively and has come up as a promising electrochromic material because of its chemical stability in many electrolytes, nice reversible color switching, and long-term cycling stability. 10,11 The niobium element characterized by several valence states from +2 to +4 to +5 for NbO, NbO 2 , and Nb 2 O 5 , respectively, 12 exists in various oxide polymorphic forms including monoclinic (H-Nb 2 O 5 ), tetragonal (M-Nb 2 O 5 ), orthorhombic (T-Nb 2 O 5 ), and pseudohexagonal (TT-Nb 2 O 5 ). The different crystal phases of Nb 2 O 5 depend on the synthesis temperature.…”

“…The electrochromic performance of niobium pentoxide depends on several parameters including the morphology and the porosity, the film thickness, the surface roughness, and the deposition method. Various deposition techniques including spray pyrolysis, radio frequency magnetron sputtering, pulsed laser deposition, chemical vapor deposition, and dip-coating techniques , have been used to prepare Nb 2 O 5 thin films. Among them, dip-coating processes present the advantage of high versatility, low cost, reasonable deposition rates, and simplicity in experimental parameter modulation.…”
