“…4c). For LiC 12 , the transmission maximum may occur at a longer wavelength than our experiment accesses, and we observe only an enhancement of long-wavelength transmission. Thus, we conclude that the overall reduction in interband transitions by Pauli blocking is responsible for the transmission increase, and the higher Drude conductivity of more strongly doped LiC 6 is responsible for the observed reduction in transmission at long wavelength and the non-monotonic doping dependence of transmission at these wavelengths.…”

“…A decrease in the absorption coefficient is also observed in graphite intercalation compounds by Hennig et al 19 In Li-intercalated graphite, the window manifests as a minimum in reflectivity occurring near 740 nm for bulk LiC 12 and 440 nm for bulk LiC 6 (ref. 32).…”

“…4c), the wavelength-dependent transmittance shows a maximum around 500 nm, and the transmittance of LiC 6 is still higher compared with pristine ultrathin graphite. Interestingly, the transmittance of LiC 6 still increases compared with LiC 12 for wavelengths well below the maximum, while above the transmittance maximum the LiC 6 transmittance decreases compared with LiC 12 .…”

“…As time increases, a second plateau appears in the voltage at B0.1 V, which we identify with the formation of LiC 12 (stage II). At the end of the 0.1 V plateau, we expect that the entire sample has been converted to LiC 12 , and the transmittance dramatically increased to 85.8% (18-layer) and 71.9% (38-layer). A third voltage plateau appears at a value of B0.05 V, indicating the formation of LiC 6 (stage I).…”

“…An excellent performance of 30 O per sq at 90% transmittance has been achieved using doped four-layer chemical-vapour deposition (CVD) graphene 9 . Bulk materials with 2D-layered structures such as graphite have also been studied and used extensively for electrochemical energy storage based on intercalation [10][11][12] . Fundamental studies on intercalation in graphite have been extensively carried out 13 , and nanostructured 2D materials have recently gained much interest 14 .…”

Various band structure engineering methods have been studied to improve the performance of graphitic transparent conductors; however, none has demonstrated an increase of optical transmittance in the visible range. Here we measure in situ optical transmittance spectra and electrical transport properties of ultrathin graphite (3-60 graphene layers) simultaneously during electrochemical lithiation/delithiation. On intercalation, we observe an increase of both optical transmittance (up to twofold) and electrical conductivity (up to two orders of magnitude), strikingly different from other materials. Transmission as high as 91.7% with a sheet resistance of 3.0 O per square is achieved for 19-layer LiC 6 , which corresponds to a figure of merit s dc /s opt ¼ 1,400, significantly higher than any other continuous transparent electrodes. The unconventional modification of ultrathin graphite optoelectronic properties is explained by the suppression of interband optical transitions and a small intraband Drude conductivity near the interband edge. Our techniques enable investigation of other aspects of intercalation in nanostructures.

Nanotubes are one‐dimensional tubular nanomaterial having a great length to diameter ratio. The substantial research interest of nanotubes for miscellaneous applications is triggered from their unusual and superlative properties. This article narrates the different types of nanotubes and their synthesis and applications. The techniques used to modify various nanotubes properties and thus its performances for various applications are also discussed. Nanotubes have been incorporated with a number of inorganic and organic materials and then used in diverse applications such as sensors, biomedical, energy storage, environmental, and engineering. The presence of tubular structure, large aspect ratio and surface area, porous nature, chemical inertness, and enhanced mechanical and thermal properties are the highlights of nanotubes for vast acceptance in broad range of applications.
