The threshold voltage value, which is the most important electrical parameter in modeling MOSFETs, can be extracted from either measured drain current or capacitance characteristics, using a single or more transistors. Practical circuits based on some of the most common methods are available to automatically and quickly measure the threshold voltage. This article reviews and assesses several of...

We report direct observation of a "Pac-Man" like coarsening mechanism of a self-supporting thin film of nickel oxide. The ultrathin film has an intrinsic morphological instability due to surface stress leading to the development of local thicker regions at step edges. Density functional theory calculations and continuum modeling of the elastic instability support the model for the process.

The residual stresses of the thin-walled injection molding are investigated in this study. It was realized that the behavior of residual stresses in injection molding parts was affected by different process conditions such as melt temperature, mold temperature, packing pressure and filling time. The layer removal method was used to measure the residual stresses at a thin-walled test sample by a...

In this study, the effect of sulfurization temperature on properties SnS thin films was investigated. The were fabricated by two-stage method includes deposition magnetron sputtering using a single target, followed annealing/sulfurization treatment in Rapid Thermal Processing (RTP) system at 225, 300 and 375 °C temperatures. Several characterization techniques such as XRD, Raman spectroscopy, E...

BACKGROUND Antidepressants can impair sexual arousal. Exercise increases genital arousal in healthy women, likely due to increasing sympathetic nervous system (SNS) activity. PURPOSE Test if exercise increases genital arousal in women taking antidepressants, including selective serotonin reuptake inhibitors (SSRIs), which suppress SNS activity, and selective serotonin and norepinephrine reupt...

Abstract Orthorhombic SnS is a promising thin-film solar-cell material composed of safe and abundant elements with suitable optical properties for photovoltaic application. For approximately two decades, solar cells have employed heterojunction structures p-type other n-type semiconductors because undoped typically exhibits electrical conduction. However, their conversion efficiency has remaine...

Tin(II) sulfide (SnS) is an attractive semiconductor for solar energy conversion in thin film devices due to its bandgap of around 1.3 eV orthorhombic polymorph, and a band gap 1.5–1.7 the cubic polymorph—both which are commensurate with efficient light harvesting, combined high absorption coefficient (10−4 cm−1) across NIR–visible region electromagnetic spectrum, leading theoretical power effi...

The substrate's nature plays an important role in the characteristics of semiconductor films because thermal and lattice mismatching between film substrate. In this study, tin sulfide (SnS) nanostructured thin were grown on different substrates (polyester, glass, silicon) using a simple low-cost chemical bath deposition technique. structural, morphological, optical properties investigated X-ray...

Thin films of tin (II) sulfide (SnS) were deposited onto a 500 µm thick copper substrate by chemical bath method. The effect sodium (Na) doping in these was studied. synthesis the performed at temperatures 60, 70, and 80 °C for 5 min. microstructure SnS analyzed scanning electron microscopy (SEM) showed compact morphology °C. edges grains rounded off with addition commercial surfactant. thickne...
