Emergent Spin Hall Quantization and High‐Order van Hove singularities in Square‐Octagonal MA2Z4

open access: yesAdvanced Physics Research, EarlyView.
Square‐octagonal MA2Z4 (M = Mo/W, A = Si/Ge, Z = pnictogen) monolayers are predicted to realize quantum spin Hall insulators with nearly quantized spin Hall conductivity enabled by an emergent spin U(1) quasi‐symmetry. Materials with Z = As and Sb host quasi‐flat bands with high‐order van Hove singularities near the Fermi level, making them promising ...

Doped or Quantum-Dot Layers as In Situ Etch-Stop Indicators for III/V Semiconductor Reactive Ion Etching (RIE) Using Reflectance Anisotropy Spectroscopy (RAS)

open access: yesMicromachines, 2021
Reflectance anisotropy spectroscopy (RAS), which was originally invented to monitor epitaxial growth, can—as we have previously shown—also be used to monitor the reactive ion etching of III/V semiconductor samples in situ and in real time, as long as the

Nanoscale Ripples at the Surface of SrTiO3 Irradiated by a Broad Low‐Energy Ar+ (7 keV) Ion Beam

open access: yesSmall, EarlyView.
Broad Ar ion beam irradiation creates self‐organized ripple nanostructures on oxide surfaces. A schematic illustrates the process, while cross‐sectional STEM imaging captures the ripple morphology. Complementary elemental mapping by EELS highlights nanoscale chemical variations, linking ion‐beam nanostructuring with structural and compositional ...
