Structural Properties of Ion‐Implanted GaP:N: Effects of Nitrogen Incorporation and Post‐Implantation Annealing

open access: yesphysica status solidi (b), Volume 263, Issue 4, April 2026.
In this study, the structural properties of ion‐implanted GaP:N alloys with different nitrogen contents are analyzed before and after annealing. The results show lattice expansion with increasing N concentration due to implantation‐induced N–P split interstitials, unlike epitaxial GaPN. Annealing reduces distortion, demonstrating ion implantation as an

Thermally Conductive Buried Aluminum Nitride for Next Generation Silicon‐on‐Insulator

open access: yesAdvanced Electronic Materials
Silicon‐on‐insulator (SOI) substrates suffer from heat‐confinement and self‐heating effects due to silicon dioxide's low thermal conductivity. Polycrystalline Aluminum nitride (AlN) films can be a good replacement for effective heat dissipation while ...

In‐Plane Targeted Positioning of Silica‐Coated PbS Quantum Dots Based on Size Differences

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 4, April 2026.
We demonstrate size‐selective placement of colloidal quantum dots (CQDs) with silica shells of different thicknesses by using a nanohole Si template. CQDs can act as single photon sources and absorbers. The silica shell thickness can be controlled independently of CQD energy states.

Flexible metal-semiconductor-metal device prototype on wafer-scale thick boron nitride layers grown by MOVPE

open access: yesScientific Reports, 2017
Practical boron nitride (BN) detector applications will require uniform materials over large surface area and thick BN layers. To report important progress toward these technological requirements, 1~2.5 µm-thick BN layers were grown on 2-inch sapphire ...

Composition and Resulting Band Alignment at the TiO2/InP Heterointerface: A Fundamental Study Combining Photoemission Spectroscopy and Theory

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
The chemical composition and band alignment are systematically investigated at the TiO2/InP heterointerface. Thin TiO2 films are deposited by ALD on atomically ordered, P‐terminated p‐InP(100). By combining UPS, XPS, and ab initio molecular dynamics, the atomistic structure and electronic alignment are revealed.

Simulation of Nitride Semiconductor MOVPE

open access: yes, 2020
This article seeks to help readers understand the MOVPE growth of nitride semiconductors as a part of science. MOVPE is the abbreviation for metalorganic vapor-phase epitaxy. Therefore, the precursors used are metalorganic gases and ammonia.
