Detection of Toxic Gases and Volatile Organic Compounds Using Highly Adsorptive Nanomaterials: A Comprehensive Assessment

open access: yesEcoMat, Volume 8, Issue 5, May 2026.
This review highlights how nanomaterials with high adsorption capacities including carbon‐based structures, transition metal oxides, 2D layers, and zeolites enable sensitive and selective detection of toxic gases and VOCs. Their tailored properties and sensing mechanisms drive the development of next‐generation gas sensors for environmental and ...

Monolithic Integration of ScAlN Modulators on Silicon‐On‐Insulator Platform

open access: yesLaser &Photonics Reviews, Volume 20, Issue 9, 6 May 2026.
Monolithic integration of scandium‐doped aluminum nitride (ScAlN) modulators on a silicon‐on‐insulator platform is reported. A multilayer electrode design enhances RF‐optical field overlap, enabling direct access to the diagonal electro‐optic coefficient and improved modulation efficiency.

Impact of Sapphire Substrate Reconstruction on the Structural, Electronic, and Photonic Properties of MoS2

open access: yesSmall, Volume 22, Issue 26, 8 May 2026.
High‐temperature reconstruction of c‐plane sapphire during MOCVD growth of MoS2 fundamentally alters the optical and electronic properties of MoS2 epilayer by introducing step‐edge driven interfacial charge transfer. Raman, PL, and KPFM reveal non‐uniform doping and strain in as‐grown films, whereas transferred layers show uniform optical and ...

Single-step Au-catalysed synthesis and microstructural characterization of core–shell Ge/In–Te nanowires by MOCVD

open access: yesMaterials Research Letters, 2018
We report on the self-assembly of core–shell Ge/In–Te nanowires (NWs) on single crystal Si substrates by Metalorganic Chemical Vapour Deposition (MOCVD), coupled to the Vapour–Liquid–Solid (VLS) mechanism, catalysed by Au nanoparticles (NPs). The NWs are

Wafer‐Scale Self‐Limiting Epitaxy of Bernal‐Stacked Single‐Crystal Boron Nitride

open access: yesSmall, Volume 22, Issue 26, 8 May 2026.
Wafer‐scale, single‐crystal Bernal‐stacked boron nitride (bBN) bilayers are grown by flow‐modulated MOCVD, where monoatomic Ni step edges on Ni(111) deterministically direct AB stacking. As an ultrathin interlayer, bBN suppresses interfacial scattering and enables robust, nonvolatile polarization switching in MoS2 channels, offering a scalable platform

Wafer bonding and layer transfer processes for 4-junction high efficiency solar cells [PDF]

open access: yes, 2002
A four-junction cell design consisting of InGaAs, InGeAsP, GaAs, and Ga0.5In0.5P subcells could reach 1 x AMO efficiencies of 35.4%. but relies on the integration of non-lattice-matched materials.

Diagnostic in CVD processes by IR pyrometry [PDF]

open access: yes, 2008
The control of CVD processes requires in situ analysis techniques and real time monitoring to identify the chemical species involved in the mechanism, to determine the growth kinetics and more generally to detect and analyze the dynamics of any event ...
