Summary: Organic electrochemical transistors (OECTs) are essential in bioelectronics and printed electronics applications due to their simple structure, ease of tunability, biocompatibility, and suitability for different fabrication routes. This study presents a hybrid direct-write additive manufacturing approach to fabricating OECTs, combining 3D printing of conducting and insulating layers with inkjet printing of semiconducting thin films. The results demonstrate that this manufacturing method can rapidly produce OECTs and neuromorphic devices with good performance.

Summary: Inkjet-printed conductive polymer PEDOT:PSS films have been developed as stretchable transparent electrodes in optoelectronic devices. By printing a formulated ink containing PEDOT:PSS, formamide, d-sorbitol, sodium dodecyl benzene sulfonate, and ethylene glycol, a uniform film with high conductivity and mechanical performance is achieved. The film shows a high conductivity of 1050 S/cm, sheet resistance of less than 145 omega/sq, and can maintain stability even after 200 cycles of stretching at 55% strain. The enhanced conductivity is due to the conformational transition of the backbone through secondary doping and post-treatment with formamide, as well as the removal of excess PSS components after phase separation.

Summary: We propose and study the hybrid integration of a 1D photonic crystal nanobeam (NB) laser on a SiNx waveguide, which can achieve over 50% directional coupling to the specific waveguide output facet while maintaining a sufficient quality factor for low-threshold lasing. Using the transfer printing technique, we successfully demonstrated the proposed hybrid integration with optimized parameters, showing significant planar laser emission from the SiNx waveguide facet in experiments with a low lasing threshold of 180 mu W. This hybrid integration with compact size, unidirectional coupling, and low lasing threshold can provide a helpful reference for designing PhC NB lasers coupled with SiNx waveguides in silicon-based photonic integrated circuits.

Summary: Microfluidic surface chemistry allows for control of capillary-driven flow without bulky external instrumentation. A novel nonhomogeneous coating is used to define regions with different wetting properties on microchannel walls, leading to different capillary pressures and automatic flow control. This method employs inkjet printing to deposit hydrophilic coatings on the surfaces of 3D-printed microfluidic devices, enabling capillary flow control in 3D-printed microfluidics for the first time. The method is further utilized to create stop and delay valves and integrated with organic electrochemical transistors for sensing applications.

Summary: We demonstrate a class of layered valley-spin hybrid (VSH) materials composed of a monolayer two-dimensional (2D) semiconductor and double-decker single molecule magnets (SMMs). The interaction of the VSH components gives rise to the intersystem crossing of the photogenerated carriers and moderate p-doping of the MoS2 monolayer. By helicity-resolved photoluminescence (PL) microspectroscopy, we observed enhanced A exciton-related valley emission at room temperature and elucidated the mechanism behind it. Our study shows the experimental feasibility and great promises of ultrathin VSH materials for opto-spintronic, valleytronic, and quantum information concepts.

Summary: 2D monoelemental materials, such as germanene and silicene, have attracted tremendous attention for their 2D layer structure and tunable electronic and optical properties. By deintercalation of a Zintl phase in a protic environment, the instability and oxidation issue of germanene and silicene were overcome. The synthesized Ge-H, Ge0.75Si0.25H, and Ge0.5Si0.5H were successfully used in photoelectrochemical photodetectors with broad response, unprecedented responsivity, and detectivity.

Summary: We investigate the intrinsic strain in twisted MoS2/MoSe2 heterobilayers and find that small twist angles result in atomic reconstructions, large moire periodicities, and high local strains. The formation of moire superlattices is assisted by stacking domain reconstructions, leading to a complex strain distribution. Larger twist angles hinder lattice reconstruction and result in moire patterns with small periodicities and negligible strains.

Summary: By advanced experimental techniques and theoretical calculations, we have investigated the pressure-temperature phase diagram of CrI3 single crystals and found that pressure can effectively control the magnetic and electrical properties of this material. Pressure reduces the ordering temperature of CrI3 and induces a transition from ferromagnetism to antiferromagnetism, as well as a phase transition from semiconductor to metal.
