“…All-CNT TFTs with a split bottom-gate structure can be fabricated by the layer-by-layer transfer technique. [202,203] Zou et al reported such all-CNT TFTs and inverter circuits, as shown in Figure 10. [203] The two kinds of CNT network were fabricated by controlling the density of the network through CVD and then successively transferring them to the flexible substrate to construct the devices.…”

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...

In the last three decades, zero-dimensional, one-dimensional, and two-dimensional carbon nanomaterials (i.e., fullerenes, carbon nanotubes, and graphene, respectively) have attracted significant attention from the scientific community due to their unique electronic, optical, thermal, mechanical, and chemical properties. While early work showed that these properties could enable high performance in selected applications, issues surrounding structural inhomogeneity and imprecise assembly have impeded robust and reliable implementation of carbon nanomaterials in widespread technologies. However, with recent advances in synthesis, sorting, and assembly techniques, carbon nanomaterials are experiencing renewed interest as the 2 basis of numerous scalable technologies. Here, we present an extensive review of carbon nanomaterials in electronic, optoelectronic, photovoltaic, and sensing devices with a particular focus on the latest examples based on the highest purity samples. Specific attention is devoted to each class of carbon nanomaterial, thereby allowing comparative analysis of the suitability of fullerenes, carbon nanotubes, and graphene for each application area. In this manner, this article will provide guidance to future application developers and also articulate the remaining research challenges confronting this field.Deep Jariwala is currently working as a graduate student under supervision of Prof. Mark

Se fabricaron y caracterizaron muestras de carbón activado y nanoplaquetas de carbón obtenidas de Guadua angustifolia Kunth empleada como precursor para aplicaciones en electrónica flexible. El carbón activado se obtuvo en un sistema de pirólisis bajo atmósfera controlada de nitrógeno a una temperatura de 573 K durante una hora y las nanoplaquetas, a una temperatura de 973 K durante una hora. El carbón se activó empleando hidróxido de sodio e hidróxido de potasio con una temperatura de activación de 973 K. Las nanoplaquetas se obtuvieron mediante procesos de molienda mecánica en mortero y procesos de cavitación durante seis horas. Las muestras de carbón activado se caracterizaron mediante isotermas de adsorción y se encontró un área superficial de 408,0 m²/g y 308,9 m²/g para el carbón activado con hidróxido de sodio e hidróxido de potasio, respectivamente. Se utilizó la difracción de rayos X para determinar la presencia de electrólitos remanentes del proceso de activación. Las imágenes obtenidas con el microscopio electrónico de barrido revelaron la estructura porosa del carbón y la presencia de las sales electrolíticas remanentes. Mediante voltametría cíclica se determinó una capacitancia específica máxima de 111 F/g. El carbón activado se empleó en la fabricación de un supercondensador flexible y se logró una capacitancia de 7,9 mF. Las nanoplaquetas se caracterizaron mediante las técnicas de difracción de rayos X, microscopía electrónica de barrido, espectrometría infrarroja con transformada de Fourier y microscopía electrónica de transmisión, con las que se corroboró la presencia de nanoplaquetas de grafito oxidado con espesores inferiores a 13 nm; las curvas de intensidad-voltaje evidenciaron un comportamiento no lineal, atribuido a efectos de percolación de los portadores de carga eléctrica. Estos resultados sugieren que el carbón activado y las nanoplaquetas de carbón son excelentes candidatos para aplicaciones electrónicas.
