Hexagonal mesoporous titanosilicates with distinguishable framework charges and textural mesoporosity, namely, Ti-MCM-41 Ti-HMS, were prepared at ambient temperature by electrostatic neutral assembly processes, respectively. Titanium incorporation the 2 mol % level for both materials was accompanied increases in lattice parameters wall thicknesses, but pore sizes remained unaffected. Cross-linking of anionic as-synthesized Ti-substituted MCM-41 S+I- S+X-I+ pathways (where S+ is a quaternary...
The increasing demand for mobile artificial intelligence applications has elevated edge computing to a prominent research area. Silicon materials, renowned their excellent electrical properties, are extensively utilized in traditional electronic devices.

An ultrathin atomic-layer-deposited (ALD) AlOx gate insulator (GI) was implemented for self-aligned top-gate (SATG) amorphous InGaZnO (a-IGZO) thin-film transistors (TFTs). Although the 4.0-nm thick exhibited ideal insulating properties, interaction between ALD and predeposited a-IGZO caused a relatively defective interface, thus giving rise to hysteresis bias stress instabilities. As analyzed using high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, Hall...
