Flexible and stretchable thin-film transistors (TFTs) are crucial in skin-like electronics for wearable and implantable applications. Such electronics are usually constrained in performance owing to a lack of high-mobility and stretchable semiconducting channels. Tellurium, a rising semiconductor with superior charge carrier mobilities, has been li...
Simulation of biological synaptic function by electronic devices based on two-dimensional (2D) semiconductors is an emerging research. However, large-scale integration of synaptic devices particularly on flexible substrate are challenging. Electrolyte-gated 2D thin film transistors with low temperature processability for large-scale production have...
On‐skin electronics require minimal thicknesses and decent transparency for conformal contact, imperceptible wearing, and visual aesthetics. It is challenging to search for advanced ultrathin dielectrics capable of supporting the active components while maintaining bending softness, easy handling, and wafer‐scale processability. Here, self‐delamina...
The search of new high‐mobility two‐dimensional (2D) semiconductors is crucial for the development of next‐generation photodetectors, since current photodetectors based on single 2D semiconductors usually cannot simultaneously own ultrafast response rate and ultrahigh sensitivity.

Aqueous zinc-ion batteries (ZIBs) have gained wide attention for their low cost, high safety, and environmental friendliness in recent years. β-MnO2, a potential cathode material for ZIBs, has been restricted by its small channels for efficient charge storage.

Rechargeable aqueous zinc-ion batteries (ZIBs) featuring low cost, superior performance, and environmental benignity have attracted dramatic attention as a promising alternative energy storage system to lithium-ion batteries. Nevertheless, the development of ZIBs is still hindered by the limited selection of cathode materials due to the large solva...
Understanding the effect of short channels on the performance of field‐effect transistors (FETs) from emerging low‐dimensional semiconductors is crucial to estimate their suitability in high‐density integrated circuits. To this end, intricate and costly equipment capable of nanoscale photolithography or e‐beam lithography is usually required to fab...
Elastomeric dielectrics are crucial for reliably governing the carrier densities in semiconducting channels during deformation in soft/stretchable field‐effect transistors (FETs). Uncontrolled stacking of polymeric chains renders elastomeric dielectrics poorly insulated at nanoscale thicknesses, thereby thick films are usually required, leading to...
Graphene is considered to be a valuable material in the field of photodetection due to its ultra-high electron mobility. However, its weak light absorption, short carrier lifetime and lack of gain mechanism limit the light responsivity of graphene at the magnitude of mA W⁻¹. Herein, based on the oxidation characteristics of eutectic gallium–indium...
Recently discovered bismuth oxychalcogenide (Bi2O2Se) has aroused great interest due to its ultrahigh carrier mobility, tunable band gap and good environmental stability, making it a promising candidate for high-performance electronics and optoelectronics.

As a burgeoning family of crystalline porous copolymers, covalent organic frameworks (COFs) allow precise atomic insertion of organic components in the topology construction to form periodic networks and ordered nanopores.

Fabrication of large-area and uniform semiconducting thin films of two-dimensional (2D) materials is paramount for the full exploitation of their atomic thicknesses and smooth surfaces in integrated circuits. In addition to elaborate vapor-based synthesis techniques for the wafer-scale growth of 2D films, solution-based approaches for high-quality...
Stretchable conductors capable of precise micropatterning are imperative for applications in various wearable technologies. Metallic nanoparticles with low aspect ratios and miniscule sizes are preferred over metallic nanowires or nanoflakes for such applications. However, nanoparticles tend to lose mutual contact during stretching. Therefore, they...
Graphene as a promising 2D material has been widely studied due to its unique properties. Transferring CVD graphene to other substrates from its original metal foil is important for its practical application. However, the removal of PMMA that is commonly used as the supporting mediator during the transferring process is troublesome, because PMMA mo...
Graphene has excellent electrical, optical, thermal, and mechanical properties that make it an ideal optoelectronic material. However, it still has some problems, such as a very low light absorption rate, which means it cannot meet the application requirements of high-performance optoelectronic devices. Here, we produce a high-responsivity photodet...
