Summary: The combination of atom probe tomography (APT) and optical spectroscopy has yielded original results in the field of semiconductor nanoscale heterostructures, providing a deeper understanding of carrier localization and recombination mechanisms in quantum-well systems through statistical correlation. Photoluminescence spectroscopy (PL) can be performed on APT samples, allowing for sequential correlations on a single nanoscale object with higher precision and accuracy.

Summary: Porosity can heavily influence the properties of nuclear-grade graphite, and electron tomography is able to visualize the sub-micron pores in three dimensions. This research demonstrates the 3D structure of both native and irradiation-induced nano-cracks in graphite, as well as the unique characteristics of graphite such as pore structure. The technique could also be useful for molecular dynamic simulations and experimental techniques related to irradiated graphite and other nuclear porous carbon-based materials.

Summary: Recent studies have discovered significant plasticity in bulk compression of single-crystal ZnS under complete darkness. The introduction of the photoindentation technique provides a new approach to understand the effects of light on dislocation nucleation and mobility. Research shows that light irradiation significantly increases the pop-in stress of dislocation nucleation near the surface of ZnS, leading to a drastic reduction in dislocation mobility.

Summary: In this study, cheap, abundant, and easily-obtained carbon fillers such as graphite and carbon black were successfully incorporated into a silicon oxycarbide matrix to obtain dense crack-free bulk composites with enhanced electrical and thermal conductivities. Raman parameters were crucial for understanding the electronic and/or phonon transport in the composites.

Summary: This article focuses on the Na2O-Ga2O3-TiO2 system in the study of transparent conductive oxides (TCOs). Materials of NaxGa4+xTin-4-xO2n-2 (n = 5, 6, and 7 and x & AP; 0.7-0.8) were characterized using neutron powder diffraction and aberration-corrected scanning transmission electron microscopy. The activation energy, depending on different structures, shows that Na+ ion conduction improves significantly from hexagonal to octagonal tunnels. New insights are provided into the relationship between crystal structure and transport properties of TCOs, which are crucial for designing and developing new optoelectronic devices.

Summary: This paper presents the challenge of high-resolution imaging of organic 2D materials using transmission electron microscopes, and demonstrates the reduction of resolution gap between achievable resolution and instrumental limit by selecting the appropriate incident electron energy. The authors find that the highest resolution of 1.9 angstrom is achieved at 120 kV, and successfully detect interstitial defects and functional groups in 2D polymer thin films.
