Transparent conductive amorphous Cd-In-Sb-O thin films were deposited on a flexible polyethylene naphthalate film by rf magnetron sputtering at room temperature. The large Hall mobility of ∼26 cm2 V−1 s−1 was observed on the films with carrier density >1020 cm−3. The carrier density varied from the order of 1020 to 1017 cm−3 with increasing the oxygen partial pressure. The Hall mobility reached up to ∼17 cm2 V−1 s−1, even at carrier density of ∼1017 cm−3. Flexible transparent filed-effect transistor was also fabricated using the Cd-In-Sb-O thin films as a channel layer and the device performance was investigated. The device exhibited a field-effect mobility of ∼0.45 cm2 V−1 s−1 and an on-off ratio of ∼102 at room temperature. 相似文献

We describe the fabrication and characterization of Near-Field Communication (NFC) devices based on highly flexible, carbon-based antennas composed of stacked graphene multilayers. This material features a high value of conductivity (4.20?*?105?S/m) comparable to monocrystalline graphite, but is much more flexible and processable. We first studied the replacement of metal with carbon antennas using computer modeling, to select the best design. Then we manufactured several devices to be used according to the communication protocol ISO/IEC 15693. The inductance of the G-paper antennas was tested before and after hundreds of thousands of bending cycles at bending radii of 45 and 90?mm. During bending the self-resonance frequency and inductance peak showed minimal variation and the resistance at 1?MHz changed from 33.09?Ω to 34.18?Ω, outperforming standard, commercial metallic antennas. The devices were successfully tested by exchanging data with a smartphone and other commercial NFC readers, matching the performance of standard, commercial metallic antennas. The graphene antennas could be deposited on different standard polymeric substrates or on textiles. Smart cards, flexible NFC tags and wearable NFC bracelets were prepared in this way to be used in electronic keys, business cards and other typical NFC applications. 相似文献

We have proposed a method for large-scale growth of thin nanotube films from solution on the surface of flexible, transparent substrates. Uniform nanotube deposition was achieved through the preparation of a stable colloidal nanotube solution in an aqueous surfactant solution. We examined the effect of the number of deposition cycles on the morphology of the films and their optical and electrical characteristics. The results demonstrate that the optical transmittance of the films decreases linearly with increasing film thickness, whereas their resistance decreases quadratically, which corresponds to three-dimensional nanotube percolation in the films. With increasing film thickness, the sheet resistance of the films drops from 400 to 15 kΩ/□ and their transmittance decreases from 85 to 40%, respectively. 相似文献
