Full encapsulated CdZnTe crystals by the vertical Bridgman method

, 2008
CdZnTe crystals were grown by the vertical Bridgman technique using boron oxide for preventing material decomposition. The experiments show that a boron oxide layer completely encapsulates the crystal during growth, so that the crystal grows without ...

Toward Optimal After‐Growth Cooling of a Single Crystal

Crystal Research and Technology, Volume 61, Issue 10, October 2026.
A novel and computationally efficient approach to generate optimal after‐growth cooling profiles is presented Optimal strategies for after‐growth cooling of a single crystal are computed for idealized cooling profiles. General scaling laws for maximum cooling rate and total cooling time as function of material and crystal properties are found ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Spectroscopic response of CZT detectors obtained by the boron encapsulated vertical Bridgman method [PDF]

, 2008
The purpose of this paper is to present the spectral response at different energies of some CZT crystals grown with the boron oxide encapsulated vertical Bridgman method by IMEM-CNR. The most important feature of the technique is that the crystal, during

Microscopic Insights into Magnetic Warping and Time‐Reversal Symmetry Breaking in Topological Surface States of Rare‐Earth‐Doped Bi2Te3

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

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.

Discovering Shared Design Heritage for Semiconductor‐Based Gamma‐Ray Spectrometers: From CdTe to Metal Halide Perovskites

Laser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
Decades of CdTe and CdZnTe gamma‐ray spectrometer development define core design principles for room‐temperature semiconductor detectors. This Review highlights how metal halide perovskites rapidly assimilate these principles, particularly through defect and compositional engineering strategies that establish favorable spectroscopic conditions for ...
