The use of additives in the fabrication of solution-processed n-type perovskite transistors alleviates lattice strain and suppresses undercoordinated lead, boosting the charge transport properties of the devices and making them suitable for use in complementary circuit applications.
Tunable and stable memristors based on single-crystalline entropy-stabilized oxide films grown on epitaxial bottom electrodes can be used to create energy-efficient reservoir computing networks.
An ingestible electronic device can record biopotential electrical signals from the gastric environment—including the gastric slow wave, respiration signal and heart signal—and can monitor slow wave activity in freely moving and feeding animals.
Robust conductive hydrogels made purely from a conducting polymer can be fabricated using a laser-induced phase separation method that also improves adhesion to a polymer substrate and allows high-resolution selective patterning.
A non-volatile memory device that is based on an aluminium scandium nitride (Al0.68Sc0.32N) ferroelectric diode can operate at temperatures of up to 600 °C.
By integrating a metal‒oxide‒semiconductor capacitor into a two-terminal diode, a multifunctional single device can be created that operates as a tunable light-emitting diode with a built-in bias tee circuit and a detector with a reconfigurable optoelectronic logic function.
A graph-based genetic programming method can be used to automatically generate small and energy-efficient circuits from tabular data for machine learning classification tasks.
A method for integrating polycrystalline molybdenum disulfide using processes in a 200 mm fab facility can create transistors with high robustness and performance comparable with single-crystalline devices.
High-density device arrays can be integrated on flexible substrates using a dip-transfer coating method that suppresses adhesive layers from forming between closely spaced devices and uses magnetically self-assembled particles to increase the anisotropic conductivity.
A measurement scheme in which current is injected simultaneously into two disconnected perimeters of a multi-terminal Corbino device can be used to increase the robustness of a zero-magnetic-field quantum anomalous Hall resistor, thus extending its operating range to higher currents.
Using an intrinsically stretchable nanocomposite of quantum dots, an elastomer and a hole transport polymer as an emissive layer, stretchable light-emitting diodes can be fabricated that exhibit high brightness even under 50% strain.
Photo-responsive metal halide perovskite light-emitting diodes can be used to create a multifunctional display that can function as a touch screen, ambient light sensor and image sensor.
A biodegradable electronic bandage that applies pulsed and d.c. electrostimulation can accelerate the healing of intestinal wounds in mice via transfection of cells and stimulation-induced secretion of healing factor from those cells.
A scalable communications protocol for transmitting spike-train data generated from multiple microchip sensors can be used with spiking neural network models for brain–machine interface and biosensing applications.
Nanofluidic devices with a large entrance asymmetry can function as memristive switches—operating on the second timescale and with a conductance ratio of up to sixty—and can be assembled into basic logic circuits.
A two-dimensional perovskite, Sr2Nb3O10, can be integrated with a range of other two-dimensional materials and act as a photoactive high-κ dielectric in the resulting phototransistors.
