“…The CNTs can be continuously drawn from the silicon wafer as the bundles are connected to spontaneously make a yarn structure. [58][59][60] The optoelectrical performance of the CNT TCFs is limited by the existence of multi-wall CNTs and their bundles, thus the prime sheet resistance is ≈1 kΩ sq -1 for a light transmittance of 83% at a wavelength of 550 nm. The performance can be improved by plasma or laser trimming and metal deposition, which leads to a sheet resistance of 208 Ω sq -1 at the transmittance of 90% or 24 Ω sq -1 at 83.4%.…”

silicon wafer, TFTs can be fabricated on various types of rigid or flexible substrates. [1] TFTs fabricated on glass are primarily used for driving circuits in the liquid-crystal displays of televisions, computer monitors, and mobile phones, etc. Well-established TFT technologies based on amorphous silicon and polycrystalline silicon are well-suited for large-area, highresolution panels, e.g., six pieces of 65-and 75-inch TFT arrays can be fabricated on a 10.5th generation glass substrate. [2] However, TFTs based on these silicon-based semiconductors still face challenges in flexible and transparent applications, which would allow circuit integration on curved and non-rigid surfaces and in multi-layer packaging, e.g., head-up displays on windshields, informational displays on eyeglasses and transparent electronic skin in wearable electronics. [3] In terms of the materials used to construct flexible and transparent devices, not only the transistor channel but also the dielectric layers and metallic interconnects should have excellent flexibility and transparency. [4] The following factors play critical roles in the selection of channel materials: carrier mobility, temperature of material preparation, flexibility, large area availability, cost and stability. Carrier mobility is an important parameter to characterize the drift velocity of electrons or holes in a semiconductor under an applied electric field. [5] A high mobility corresponds to a high operating speed of the TFTs and their circuits. The only advantage of low-temperature polycrystalline silicon is its relatively high mobility. [6] Amorphous oxide semiconductors, including indium gallium zinc oxide, have a modest mobility and are costly due to the use of noble metal elements. [7] Hydrogenterminated amorphous silicon has modest properties in carrier mobility, large-area and flexibility, [1] and organic semiconductors are better suited for flexible and transparent TFTs except for their shortcomings of low mobility and poor environmental stability. [8] On the other hand, normal metal electrodes, such as gold, silver, aluminum and copper, cannot be used to form transparent electrodes due to their poor light transmittance. Both transparent indium tin oxide (ITO) electrodes and opaque metal electrodes suffer from flexibility constraints and can usually tolerate strains of less than 2%. [9][10][11] Therefore, the discovery of new types of robust channel and electrode materials is essential to achieve transparent, flexible, and even stretchable electronics. [12] Carbon nanomaterials, such as carbon nanotubes (CNTs) and graphene, have attracted great attention for potential use in flexible and transparent electronics since their discovery in the last two decades, [13,14] owing to their excellent properties Carbon nanotubes and graphene have attracted great attention for potential applications in flexible and transparent electronics, owing to their exceptional properties including very high electrical conductivity, optical transmittance, mechanical strength and f...

“…Since the report of a dry-drawing method in 2002 [10], much effort has been focused on scaling up the growth of superaligned CNT arrays [11][12][13]. Due to their high-purity, high-quality and ordered structure, the superaligned CNT arrays can be converted into continuous fibers or sheets in the dry state [2,10,11,[14][15][16][17][18].…”

“…[26][27][28] Using a laser-machining technique, the asymmetric rectangular aperture arrays with different periods were tailored on 3 µm-thick MWCNT films, and the morphologies of the MWCNT films were observed by a scanning electron microscopy (SEM, FEI SIRION 200 SEM, State of Oregon, USA), as shown in Figure 1(a). The optical microscopy (DM2500, Leica, Germany) images of samples A and B were shown in Figure 1(c) and 1(d).…”

Transmission properties of terahertz waves through asymmetric rectangular aperture arrays on carbon nanotube films

2016

Transmission spectra of terahertz waves through a two-dimensional array of asymmetric rectangular apertures on super-aligned multi-walled carbon nanotube films were obtained experimentally. In this way, the anisotropic transmission phenomena of carbon nanotube films were observed. For a terahertz wave polarization parallel to the orientation of the carbon nanotubes and along the aperture short axis, sharp resonances were observed and the resonance frequencies coincided well with the surface plasmon polariton theory. In addition, the minima of the transmission spectra were in agreement with the location predicted by the theory of Wood’s anomalies. Furthermore, it was found that the resonance profiles through the carbon nanotube films could be well described by the Fano model.
