“…Based on those detailed and in-depth fundamental studies discussed in the last section, the general growth behavior of deposited Au on different substrates has been fully understood. In recent years, more and more applications based on UTGL configurations have been reported, including the examples from optical applications, 6,7,96–106 electronic device applications, 107–115 and as seed layers. 116–125…”

“…Previous studies successfully prepared Au [11], Ag [50], Cu [51], Al [49], Cr [52], Ni [46], and other metal thin films. The preparation methods were mainly room-temperature sputtering deposition [48] and high-temperature thermal deposition [53]. The growth of a metal film on a substrate is generally divided into three stages (nucleation, coalescence, and thickness growth), and the performance of the film is affected by the various sputtering conditions.…”

“…Furthermore, Cr and Ni films can maintain high optical transparency in the full wavelength range [61], while metal films such as Ag maintain high light transmittance only at specific wavelengths. In the ultra-thin gold-silver-gold multilayer film thermally deposited on flexible substrates by Bauch et al, the transmission spectrum was extended [53]. In addition, the stability of Ag thin films is poor.…”

With the rapid development of flexible electronic devices (especially flexible LCD/OLED), flexible transparent electrodes (FTEs) with high light transmittance, high electrical conductivity, and excellent stretchability have attracted extensive attention from researchers and businesses. FTEs serve as an important part of display devices (touch screen and display), energy storage devices (solar cells and super capacitors), and wearable medical devices (electronic skin). In this paper, we review the recent progress in the field of FTEs, with special emphasis on metal materials, carbon-based materials, conductive polymers (CPs), and composite materials, which are good alternatives to the traditional commercial transparent electrode (i.e., indium tin oxide, ITO). With respect to production methods, this article provides a detailed discussion on the performance differences and practical applications of different materials. Furthermore, major challenges and future developments of FTEs are also discussed.

“…Other alternatives include ultrathin metals, [ 8–11 ] conductive polymers, [ 12–14 ] carbon nanotubes, [ 15,16 ] graphene‐based layers, [ 17–21 ] nanowires, [ 22–25 ] dielectric‐metal‐dielectric structures, [ 26–31 ] and metal networks. [ 32,33 ] Of these alternatives, metal nanowires and dielectric‐metal‐dielectric structures are the most promising, as they exhibit low sheet resistance below 10 Ω Sq −1 and above 90% absolute transmittance.…”

The design of transparent conductive electrodes (TCEs) for optoelectronic devices requires a trade‐off between high conductivity and transmittivity, limiting their efficiency. This paper demonstrates the best ever achieved TCEs with the novel approach to fabricating TCEs that effectively alleviates this trade‐off: a monolithic high contrast grating integrated with metal (metalMHCG). The metalMHCG enables higher electrical conductivity than other TCEs, while providing transmissive and antireflective properties. It focuses on infrared spectrum TCEs, which are essential for sensing, thermal imaging, and automotive applications. However, due to elevated free carrier absorption, they are much more demanding than TCEs for the visible spectrum. It demonstrates a record 75% absolute transmittiance of unpolarized light, resulting in a record 108% transmittance relative to plain GaAs substrate. It achieves even larger absolute transmittance of polarized light, reaching 92% or 133% relative transmittance. Despite the record high transmittance, the sheet resistance of the metalMHCG is the best ever reported, several times lower than any other TCE, ranging from 0.5 to 1 Ω Sq−1.
