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.

Robust Reaction-Transport Models of Movpe Reactors

open access: yes, 1997
A simple gas-phase and surface kinetic model describing the Metalorganic Vapor Phase Epitaxy (MOVPE) of GaAs from trimethyl-gallium (TMG) and arsine has been extracted from reported reaction mechanisms through sensitivity analysis. This model was coupled

Deterministic hBN Bubbles as a Versatile Platform for Studies on Single‐Photon Emitters

open access: yesAdvanced Functional Materials, Volume 36, Issue 24, 23 March 2026.
Single‐photon emitters (SPEs) in hBN are promising for quantum technologies; however, in exfoliated samples their activation is required, limiting reproducibility of previous studies. This work introduces a large‐area MOVPE‐grown hBN platform that hosts SPEs without prior activation.

Vacancy‐Type Defects in n‐Type GaN Fabricated by Low‐Dose Ion Implantation Studied by a Monoenergetic Positron Beam

open access: yesphysica status solidi (b), Volume 263, Issue 3, March 2026.
Vacancies in low‐dose ion‐implanted GaN are studied by positron annihilation. Depth profiles of the net donor concentration (ND) are close to those for implanted impurities, but ND is 2–3 times higher than concentrations of implanted ions. The origin of donor‐like defects is expected to be N‐vacancy‐related defects, and Ga‐vacancy‐type defects play a ...

High‐Temperature Operation of All‐Molecular Beam Epitaxy InAs/GaAs Quantum Dot Lasers on V‐Grooved Si (001)

open access: yesphysica status solidi (a), Volume 223, Issue 4, 24 February 2026.
We demonstrate thermally reliable all‐MBE InAs/GaAs quantum dot lasers directly grown on V‐grooved Si (001). By preventing V‐groove deformation and eliminating micro‐cracks, the device achieves a maximum pulsed operating temperature of 150°C. This establishes a robust, scalable platform for monolithic Si photonics.
