Epitaxial growth of visible to infra-red transparent conducting In₂O₃nanodot dispersions and reversible charge storage as a Li-ion battery anode

Abstract

. (2013) AbstractUnique bimodal distributions of single crystal epitaxially grown In2O3 nanodots on silicon are shown to have excellent IR transparency greater than 87% at IR wavelengths up to 4 µm without sacrificing transparency in the visible region. These broadband antireflective nanodot dispersions are grown using a two-step metal deposition and oxidation by molecular beam epitaxy, and backscattered diffraction confirms a dominant (111) These properties could potentially lead to further development of similarly controlled dispersions of a range of other active materials to give transparent battery electrodes or materials capable of non-destructive in-situ spectroscopic characterization during charging and discharging.3

Epitaxial growth of an antireflective, conductive, graded index ITO nanowire layer

“…As with the thick porous films, the ITO layer contains a (222) texture, but this remains dominant since the NWs grow from nanoparticles with a (111) surface termination. We previously confirmed through electron back scattered diffraction that these nanoparticles grow with their (111) planes parallel to the substrate (10). Electron diffraction measurements shown in Figure 4D show that the NWs are composed of monocrystalline (In 1.875 Sn 0.125 )O 3 , in good agreement with the TEM measurements of the thinner layers.…”

“…Doping with Sn drastically enhances its electrical conductivity with only a slight compromise in visible wavelength transparency, thus making it a primary TCO. As the most important transparent conducting oxide, tin-doped indium oxide has also found a wide range of applications from photovoltaics to Li-ion battery materials (9,10).…”

Carbon‐Sheathed MoS2 Nanothorns Epitaxially Grown on CNTs: Electrochemical Application for Highly Stable and Ultrafast Lithium Storage

“…Therefore, developing MoS 2 /carbon hybrids with strong interfacial bonding and unstacked nanobuilding blocks is crucially desired. Epitaxial architectures, in particular, are highly attractive candidates, as they offer a feasible means to combine multiple functionalities in single nanostructures by forming a nanoscopic/atomic close interface, e.g., fast charge transfer kinetics and durable microstructure. Nevertheless, due to several matching constraints, such as lattice constants and atomic arrangement, the heteroepitaxial growth of MoS 2 /carbon core–shell structures remains a challenge.…”

A Lamellar Yolk–Shell Lithium‐Sulfur Battery Cathode Displaying Ultralong Cycling Life, High Rate Performance, and Temperature Tolerance

“…[ 22 , 23 ] As displayed in the O 1s spectrum (Figure S4c , Supporting Information), lattice oxygen peaks at 530.0, 531.9, and 532.5 eV correspond to —OH stems from In(OH) 3 , In—O, and C—O/C═O, respectively. [ 24 ] Figure S4d (Supporting Information) shows the high‐resolution XPS spectrum of the C 1s. An asymmetric peak at 284.8 eV is associated with sp 2 carbon, while other peaks are assigned to C—N/C═N and O—C═O.…”
