Flexible surface-enhanced Raman scattering (SERS) substrates are very promising to meet the needs for real-time and on-field detection in practical applications. However, high-performance flexible SERS often suffer from complexity high cost fabrication, limiting their widespread Herein, we developed a facile method fabricate multicavity substrate composed of silver nanoparticle (AgNP)-decorated aluminum hydrous oxide nanoflake array (NFA) grown on polydimethylsiloxane (PDMS) membrane.

Inverted perovskite solar cells (IPSCs) have become a research hotspot in the field of photovoltaics due to their excellent photovoltaic performance, minimal hysteresis, and low fabrication costs. Poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), as an inexpensive hole transport material, has been widely applied IPSCs. However, PEDOT:PSS drawbacks such energy‐level mismatch with perovskite, severe interfacial defects, rate, conductivity. Therefore, modifying improving is...

Large-area, vertically aligned silicon nanowires with a uniform diameter along the height direction were fabricated by combining in situ-formed anodic aluminum oxide template and metal-assisted chemical etching. The etching rate of Si catalyzed using thick Au mesh is much faster than that thin one, which suggested to be induced charge transport process. contact produces low Au/Si Schottky barrier height, facilitating injection electronic holes from Si, thus resulting high rate.

Gold nanospheres (AuNSs) were partly embedded into silicon through metal-assisted chemical etching, producing multiple-dimensional coupling of the plasmon resonances with induced image charges in surrounding medium.
