Room Temperature Synthesis and Photopatterning of Mesoporous Titanium Dioxide Thin Films

Advanced Materials Technologies, EarlyView.
A nanofabrication strategy combining deep‐UV photolithography with block copolymer self‐assembly enables direct patterning and mineralization of mesoporous TiO2 thin films at room temperature. Photocatalytic titanium oxo‐clusters promote polymer degradation under UV irradiation, enabling multiscale control over porosity, film thickness, and lateral ...

Amido‐Amine Co(II) Precursor‐Based Atomic/Molecular Layer Deposition Processes for Cobalt‐Organic Thin Films and Their Thermal Conversion to CoO Thin Films

Advanced Materials Technologies, EarlyView.
Three new atomic/molecular layer deposition processes are developed for Co‐organic thin films using a promising all‐nitrogen‐coordinated cobalt precursor. The study examines film growth, reaction mechanisms, chemical stability, and decomposition pathways of the resulting films through extensive characterization techniques and DFT calculations ...

Enhanced Self‐Phase Modulation in Silicon Nitride Waveguides Integrated With 2D MoS2 Films

Advanced Materials Technologies, EarlyView.
ABSTRACT On‐chip integration of 2D materials provides a promising route toward next‐generation integrated optical devices with performance beyond existing limits. Here, significantly enhanced spectral broadening induced by self‐phase modulation (SPM) is experimentally demonstrated in silicon nitride (Si3N4) waveguides integrated with 2D monolayer ...

Electrically Reconfigurable Nonvolatile Transmissive Metasurface in Visible

Advanced Optical Materials, EarlyView.
An electrically reconfigurable, non‐volatile metasurface operating in the visible spectrum is demonstrated using just 20 nm thick wide‐bandgap phase change material Sb2S3. On integration with a custom ultrathin silicon micro‐heater, the device achieves reversible switching with a 16 nm resonance tuning range at 610 nm, a wavelength largely under ...

Ultrafast dynamics of hot charge carriers in an oxide semiconductor probed by femtosecond spectroscopic ellipsometry

New Journal of Physics, 2020
Many linked processes occur concurrently in strongly excited semiconductors, such as interband and intraband absorption, scattering of electrons and holes by the heated lattice, Pauli blocking, bandgap renormalization and the formation of Mahan excitons.
