Developing scalable strategies of miniaturization and integration is key for achieving high-density integrated circuit devices. Here, the authors propose a silicon-based one-transistor device with a 40% reduction in circuit footprint, which combines the functionalities of logic gates, memory, and artificial synapses for mass production.

Nanoscale light manipulation and characterization are essential in nano-optics, but conventional microscopy or indirect imaging methods are often limited by low resolution or invasive nature. Here, a non-destructive light-field imaging with ~20 nm resolution is realized by p-n junction photodetection in graphene controlled by gate voltage.

Stable performance is a key requirement for solar cell devices. Here, spectroscopy combined with depth profiling reveals I₂ and PbI₂ are distributed evenly in a perovskite solar cell under an electric field, while the electric field itself promotes chemical heterogeneity and device degradation.

Understanding grain morphology and kinetics of solid-phase crystallization is important for controlling the functional properties of polycrystalline materials. Here, in situ coherent X-ray diffraction imaging and transmission electron microscopy elucidate quantitatively the kinetics of a single-grain growth in Zr-doped In₂O₃ films.

Visualizing the composition of grain networks is key for understanding the structure evolution and functional properties of composite materials. Here, X-ray fluorescence tomography, coupled with an absorption correction algorithm, reveals mechanistic insights in the phase transformations and transport properties of a mixed ionic-electronic conductor.

The COVID-19 pandemic highlights the importance of materials that block airborne virus transmission. Here, a nanostructured membrane is shown to filter coronavirus-sized particles, while the membrane surface incorporates enzymes that denature the SARS-CoV-2 spike protein within 30 s.
