Effect of Er dopant in GaSb bulk crystals grown by vertical Bridgman technique [PDF]

Journal of Crystal Growth, 1999
The distribution of Er in bulk GaSb ingots grown by vertical Bridgman technique has been investigated for different concentrations. The resistivity, mobility and carrier density were analysed. The formation of Er-Sb compounds and the incorporation of Er at subgrain boundaries has been shown by cathodoluminescence studies.

Co‐Firing Slow Solidification Process for Growing Indium‐Doped Cs3Cu2I5 Single Crystals With Record‐Breaking X‐Ray Detection Performance

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
A novel brand‐new co‐firing slow solidification process has been used to prepare Cs3Cu2I5: In single crystals (SCs), which demonstrate record‐breaking X‐ray detection performance. The regular‐shaped Cs3Cu2I5: In wafer obtains a high light yield (74 368 Ph MeV−1), which is the highest related to indium‐doped Cu‐based perovskites.

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Microstructure Evolution in Directionally Solidified Fe–C–Mn–(Si) Peritectic Steels

steel research international, Volume 97, Issue 6, Page 3133-3142, June 2026.
This study investigates how growth velocity and silicon additions affect dendritic morphology, primary arm spacing, and mushy‐zone evolution in directionally solidified quaternary peritectic steels. Silicon substantially broadens the freezing range and lengthens the mushy zone, increasing susceptibility to interdendritic cracking.

The Importance of Microstructure When Gauging the Efficacy of Pulse Poling in Perovskite Single Crystals

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Perovskite PMN‐PZT single crystals grown via solid‐state crystal growth (SSCG) were subjected to the pulse poling process to boost piezoelectric performance. Pulse poling subjects samples to short pulses of electric field in rapid succession and has previously demonstrated vast property improvements in Bridgman‐grown single crystals by driving
