Summary: This study presents the direct growth of single-phase epitaxial Hf0.5Zr0.5O2 films with non-centrosymmetric orthorhombic structure on electrode-free corundum substrates using pulsed laser deposition. The high-quality films belong to the Pca2(1) space group with [111] out-of-plane orientation. The surface of the films exhibits an atomic step-terrace structure with a corrugation of one atomic layer, and the films consist of grains with around 10 nm lateral size as observed by atomic force microscopy and scanning transmission electron microscopy. The polar nature of the films is confirmed by pyroelectric measurements, providing insights into the mechanisms of epitaxial stabilization of the ferroelectric phase of hafnia.

Summary: A new type of continuous zincblende and wurtzite defect axis that forms an angle of 70.3 degrees with the crystal growth direction was discovered. In contrast to the conventional ZB-WZ stacking fault that aligns with the crystal growth axis, a novel heteroaxial ZB-WZ stacking fault axis that intercepts the growth axis by 70.3 degrees was observed and analyzed in this study. The formation of this heteroaxial ZB-WZ stacking fault is attributed to the nanocrystals' tendency to achieve the lowest possible systematic disorder by avoiding atomic array distortion at the intersection of two tetrahedral polytypic interphases.

Summary: Understanding the phase transitions of ultrathin metal silicides is crucial for the development of nanoscale silicon devices. In this study, the phase transition of ultrathin Ni silicides on Si(100) substrates was investigated using in situ synthesis and characterization methods. The results showed the formation of an ultrathin epitaxial layer and ordered structures at the interface upon room-temperature deposition. At 290 degrees C, a direct transition from the orthorhombic delta-Ni2Si phase to the final NiSi2-x phase was observed, skipping the intermediate monosilicide phase. The thickness of the ordered delta-Ni2Si layer was found to be limited due to competition between different crystal orientations.

Summary: There is a growing demand for the development of augmented reality and virtual reality devices, which requires micro-LEDs (mu LEDs) with a dimension of <= 5 μm as key elements. However, the current fabrication process using dry-etching technologies results in severe degradation in optical performance, especially when the dimension of LEDs is <= 10 μm. To overcome this challenge, the Sheffield team has developed a direct epitaxial approach to achieve mu LEDs, eliminating the need for dry-etching technologies. This paper provides a comprehensive review of this technology and demonstrates the integration of multiple devices on a single chip.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
