Ab initio study of the phase diagram of epitaxial BaTiO3
, 2004 Using a combination of first-principles and effective-Hamiltonian approaches, we map out the structure of BaTiO3 under epitaxial constraints applicable to growth on perovskite substrates. We obtain a phase diagram in temperature and misfit strain that is

Germanium‐Based Mid‐Infrared Integrated Photonics
Laser &Photonics Reviews, EarlyView.The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Nonlinear Resonance Modulation in Single‐Crystalline VO2‐Integrated Si Ring Resonator
Laser &Photonics Reviews, EarlyView.This work first demonstrates a single‐crystalline VO2–Si hybrid ring resonator. The epitaxial lift‐off process enables high‐quality VO2 integration on the dissimilar Si photonic platform. The high‐quality VO2 film exhibits exceptional nonlinear resonance modulation and a steep optical transition across the metal‐insulator transition. ABSTRACT The metal‐

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications
physica status solidi (RRL) – Rapid Research Letters, EarlyView.2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

The Tetragonal to Orthorhombic structural phase transition in multiband FeAs-based superconductors
, 2009 We report the temperature dependent x-ray powder diffraction of the FeAs-based superconductors in the range between 300 K and 95 K. In the case of NdOFeAs we have detected the structural phase transition from the tetragonal phase, with P4/nmm space group,

Small Methods, EarlyView.Time‐resolved synchrotron X‐ray scattering coupled with mechanochemical synthesis reveals the structural evolution of oxyhalide superionic conductors. Oxygen incorporation governs reaction kinetics, amorphization, and microstructural transformations, while enabling efficient Li‐ion diffusion. This study highlights critical correlations between reaction

Effect of in-plane strain anisotropy on (011) epitaxial BaTiO3 and PbTiO3 thin films
AIP Advances, 2017 Misfit strain phase diagrams of single-domain (011) epitaxial BaTiO3 and PbTiO3 thin films are computed using a thermodynamic phenomenological approach. In the case of (001) epitaxial films, the two orthogonal in-plane misfit strains are equivalent. For (

steel research international, EarlyView.This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.
