P–N junctions exist in many solid‐state organic devices, such as light‐emitting diodes, solar cells, and thermoelectric devices. Creating P–N junctions by bulk chemical doping in a single organic material (like silicon doped by boron and phosphorus) may capitalize the vast scientific and technological groundwork established in the inorganic semiconducting field. However, high‐performance single‐organic‐material P–N junctions are seldom reported, because the diffusion of the dopant counterions often leads to transient rectification properties. Herein, a new type of lateral fully organic diodes created in single donor–acceptor (D–A) copolymer films with only one P‐type dopant is reported. The achieved lateral devices exhibit high current densities of ≈3.83 A cm−2 and a high rectification ratio of ≈2100, which are beyond the requirements for high‐frequency identification tags. The P‐ to N‐type polarity switching mechanism is proposed after spectroscopic and structural tests. Decent stability of the organic diode is obtained, which is due to the long channel length and low diffusion speed of the large size of dopants. This work opens the opportunities to create P–N junctions in ways of silicon‐based inorganic semiconductors and promises new opportunities for integrating organic materials for flexible and printable organic devices.

“…In the past decades, sustained research effort has been devoted to developing novel nanofabrication technologies that permit the rational design and precise control of metallic configurations from 0D to 3D. To date, several technologies, such as chemical synthesis, self‐assembly, optical/electron‐beam lithography, focused ion beam, and 3D printing, have demonstrated distinct advantages and revealed great potential for the flexible nanostructuring of metals. However, all of these technologies suffer from insuperable problems in fabricating arbitrary 3D metallic micro/nanostructures.…”

“…Self‐assembly approaches provide a controllable avenue to construct 2D and 3D micro/nanostructures by making full use of the interactions between individual nano‐building‐blocks, but the assembly process cannot be predesigned freely. To construct metallic structures according to design, lithography techniques have been widely adopted for fabricating 2D metal patterns, and the resolution can currently reach a few nanometers; nevertheless, lithography strategies are naturally 2D processing routes and are not capable of 3D fabrication. Recently, 3D‐printing technology has made it possible to construct 3D metallic structures on a macroscopic scale .…”

The past decade has seen growing research interest in developing novel fabrication methodologies for metallic micro/nanostructures toward the rational design and integration of 0D to 3D metallic configurations. Among the various fabrication techniques, femtosecond‐laser direct writing has emerged as a prominent approach to reach this goal and greatly facilitates the development of metallic micro/nanostructure‐enabled applications. Here, a series of femtosecond‐laser‐mediated fabrication strategies, including the two‐photon reduction of metal ions, template‐assisted metal coating and metal filling, photodynamic assembly of metal nanoparticles, and selective nanoparticle sintering, are summarized. Additionally, abundant applications in microelectronics, metamaterials, near‐field optics, microfluidics, micromechanics, and microsensors are introduced in detail. Current challenges and future perspectives in this field are also discussed.

“…However, their low productivity and high cost are barriers to pattern such structures. [10][11][12][13] Among the many fabrication techniques developed for producing nanopatterned surfaces, soft lithography using PDMS has been extensively employed as a robust, inexpensive, and simple method to replicate nano/micro structures. 14 In recent years, soft lithography has emerged as promising and inexpensive technique to pattern functional, metallic, ceramic and polymeric structures with a good pattern transfer between the mould and patterned structures.…”

Fabrication of hybrid nanostructured arrays using a PDMS/PDMS replication process

2012

In the study, a novel and low cost nanofabrication process is proposed for producing hybrid polydimethylsiloxane (PDMS) nanostructured arrays. The proposed process involves monolayer self-assembly of polystyrene (PS) spheres, PDMS nanoreplication, thin film coating, and PDMS to PDMS (PDMS/PDMS) replication. A self-assembled monolayer of PS spheres is used as the first template. Second, a PDMS template is achieved by replica moulding. Third, the PDMS template is coated with a platinum or gold layer. Finally, a PDMS nanostructured array is developed by casting PDMS slurry on top of the coated PDMS. The cured PDMS is peeled off and used as a replica surface. In this study, the influences of the coating on the PDMS topography, contact angle of the PDMS slurry and the peeling off ability are discussed in detail. From experimental evaluation, a thickness of at least 20 nm gold layer or 40 nm platinum layer on the surface of the PDMS template improves the contact angle and eases peeling off. The coated PDMS surface is successfully used as a template to achieve the replica with a uniform array via PDMS/PDMS replication process. Both the PDMS template and the replica are free of defects and also undistorted after demoulding with a highly ordered hexagonal arrangement. In addition, the geometry of the nanostructured PDMS can be controlled by changing the thickness of the deposited layer. The simplicity and the controllability of the process show great promise as a robust nanoreplication method for functional applications.
