“…In contrast to the removal of OCFGs that occurs during the reduction of GO, doping methods introduce foreign atoms such as nitrogen, boron, and sulfur into the chemical structure of GO, thus enabling new material properties. The doping methods mainly consist of laser [180] , chemical [181] , plasma [182] , and annealing based doping [183] . For laser doping, the doped area can be well controlled and patterned with a focused laser beam, but is often challenging for patterning large areas in a short time.…”

Integrated photonic devices operating via optical nonlinearities offer a powerful solution for all-optical information processing, yielding processing speeds that are well beyond that of electronic processing as well as providing the added benefits of compact footprint, high stability, high scalability, and small power consumption. The increasing demand for high-performance nonlinear integrated photonic devices has facilitated the hybrid integration of novel materials to address the limitations of existing integrated photonic platforms, such as strong nonlinear optical absorption or an inadequate optical nonlinearity. Recently, graphene oxide (GO), with its large optical nonlinearity, high flexibility in altering its properties, and facile fabrication processes, has attracted significant attention, enabling many hybrid nonlinear integrated photonic devices with improved performance and novel capabilities. This paper reviews the applications of GO to nonlinear integrated photonics. First, an overview of GO’s optical properties and the fabrication technologies needed for its on-chip integration is provided. Next, the state-of-the-art GO nonlinear integrated photonic devices are reviewed, together with comparisons of the nonlinear optical performance of different integrated platforms incorporating GO. Finally, the challenges and perspectives of this field are discussed.

“…Plasma technology can improve the surface properties of materials while minimizing damage due to bonding breakage of high-energy electrons and free radicals, such as doping, covalent bond breaking, ion impact, etc. Among them, especially the active screen plasma (ASP) technology, which is derived from plasma technology, overcomes the traditional defects of plasma, such as hollow cathode and edge effect, and introduces heterogeneous elements to give more possibilities of plasma . In ASP, the cathode potential is applied to a metal screen surrounding the sample stage.…”

The lower intrinsic capacity and electron/ion transfer rate of Li 4 Ti 5 O 12 limit its application and commercialization in high-specific-energy batteries. In this work, Li 4 Ti 5 O 12 /CuO heterojunctions are constructed by depositing CuO ultrafine nanoparticles on Li 4 Ti 5 O 12 nanosheets using a controllable and high-efficiency active screen plasma (ASP) technique. It is found that the rich interface and built-in electric field provided by the heterojunction enhance the electron conductivity and ionic conductivity, and density functional theory calculations confirm that the heterojunction reduces the band gap and enhances the adsorption energy for lithium ions; in the lithium storage process, the conversion reaction between CuO and lithium ions not only provides additional capacity but also the product Cu facilitates electron transport and accelerates the electrochemical process. In addition, the increase in vacancies and specific surface area due to high-energy particle bombardment contributes to the increase in conductivity and the number of active sites, and the treated sample exhibits excellent reversible capacity (182.6 mAh•g −1 at 1C), high rate performance (170.6 mAh•g −1 at 30C), and long cycle stability (136.7 mAh•g −1 after 4500 cycles at 20C) in the half-cell, and the full cell assembled with NMC811 maintained 227.4 mAh•g −1 after 700 cycles at 1C.
