Impact of Grain Size on Low‐Temperature Carrier Phase Coherence Length in Polycrystalline Halide Perovskite Films

open access: yesAdvanced Materials Interfaces, EarlyView.
Magnetoresistance measurements on a series of polycrystalline cesium tin iodide (CsSnI3) thin film devices having varying grain sizes reveal no power law dependence with clear signatures of weak anti‐localization (spin‐orbit coupling). Surprisingly, the extracted phase coherence lengths are found to be independent of grain sizes.

Strain Engineering of Ge Quantum Wells in Planar Ge/Si1 − xGex Heterostructures

open access: yesAdvanced Materials Interfaces, EarlyView.
Germanium is explored as a promising semiconductor for quantum applications due to long hole spin coherence, superconducting correlations, and CMOS compatibility. This work investigates in‐plane and out‐of‐plane strain in Ge quantum wells embedded in Si1 − xGex barriers to engineer the electronic properties of the wells.

Enhancing Grayscale E‐Beam Lithography: Thermal Treatment of Novolak‐Based Resist for 3D Nanostructures

open access: yesAdvanced Materials Interfaces, EarlyView.
Surface roughness and chemistry of novolak‐based grayscale resists are dependent on both exposure dose and post‐exposure thermal treatment. The observed trends align with the viscoelastic phase separation model and underscore the need to consider both thermodynamic and kinetic factors in resist processing. By tailoring thermal treatment, it is possible
