  • Core-shell structured quantum dots such as AgInxGa1−xS2 are promising materials for optoelectronics, but their compositional distribution remains poorly understood. Here, the authors characterize their structure at the atomic scale in 3D and reveal nanoscale compositional gradients.

  • Intrinsically stretchable electronic devices are interesting for wearable electronics, soft robotics, and stretchable display applications. Here, the authors report the fabrication of intrinsically stretchable solution-processed thin-film transistors based on 2D MoS2 flakes, showing high performance and stability under strain up to 20%.

  • Kong et al. report 1-nm-thick epitaxial AlN passivation for 1.5-µm-diameter InGaN red micro-LEDs by Ar plasma assisted atomic layer deposition, resulting in an efficiency of 6.5% at 649 nm. A near-complete device transfer to polyimide substrates further enables high-resolution flexible micro-LEDs.

  • Advanced electron microscopy and spectroscopy techniques can reveal useful structural and chemical details at the nanoscale. An unsupervised deep learning approach helps to reconstruct 3D images and observe the relationship between optical and structural properties of semiconductor nanocrystals, of interest in optoelectronic applications.
