Dependence of RF Sputtering Power on Structural and Electrical Properties of SnO Thin Films.

SnO thin films were deposited on Si substrates by radio frequency (RF) magnetron sputtering technique, and the effects of different sputtering power (60-90 W) on the structural, surface morphological, and electrical properties of the film were investigated with XRD, Raman, AFM, SEM, and fore point probe. The deposited SnO film at lower RF was amorphous, while well-defined intense XRD signals at higher RF power indicated significant improvement in crystalline nature. E and A vibrating modes related to SnO were clearly observed in the Raman spectra.

A Comparison of the Electrical Properties of Gel Polymer Electrolyte-Based Supercapacitors: A Review of Advances in Electrolyte Materials.

Flexible solid-state-based supercapacitors are in demand for the soft components used in electronics. The increased attention paid toward solid-state electrolytes could be due to their advantages, including no leakage, special separators, and improved safety. Gel polymer electrolytes (GPEs) are preferred in the energy storage field, likely owing to their safety, lack of leakage, and compatibility with various separators as well as their higher ionic conductivity (IC) than traditional solid electrolytes.

Nanoscale morphology, optical dynamics and gas sensor of porous silicon.

We investigated the multifaceted gas sensing properties of porous silicon thin films electrodeposited onto (100) oriented P-type silicon wafers substrates. Our investigation delves into morphological, optical properties, and sensing capabilities, aiming to optimize their use as efficient gas sensors. Morphological analysis revealed the development of unique surfaces with distinct characteristics compared to untreated sample, yielding substantially rougher yet flat surfaces, corroborated by Minkowski Functionals analysis.

Design and Fabrication of Ultracapacitor based on Paper Substrate and BaTiO3/PEDOT: PSS Separator Film.

Background: In this study, the ultracapacitor has been fabricated based on the BaTiO3/ PEDOT: PSS separator film and polyvinyl alcohol (PVA) electrolyte. On the paper-substrate was coated a film of the graphite nanoparticles (GNPs) as an electrode. The GNPs and surface morphology of the separator, electrolyte and electrode have been characterized using transmission electron microscopy (TEM) and scanning electron microscopy (SEM) respectively.

Sensitive Capacitive-type Hydrogen Sensor Based on Ni Thin Film in Different Hydrogen Concentrations.

Background: Hydrogen sensors are micro/nano-structure that are used to locate hydrogen leaks. They are considered to have fast response/recovery time and long lifetime as compared to conventional gas sensors. In this paper, fabrication of sensitive capacitive-type hydrogen gas sensor based on Ni thin film has been investigated.
