Semiconductor sensors based on nanosized Pd-containing tin dioxide have been obtained by a sol-gel technique. Semiconductor gas-sensitive materials were characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD) methods. Influence of Pd additives on sensitivity of the sensors to methane has been studied. Temperature dependences of electrical resistance in air and sensor...

In this paper, we studied heat transfer properties of a single tin dioxide nanobelt using non-contact high resolution thermoreflectance imaging technique. Temperature difference across the nanobelt was created by attaching its both ends to a microfabricated thin film heater and sensor pair. High resolution thermal images of the nanobelt and thin film devices were obtained at variant pulsing cur...

Alloy electrode material like tin dioxide (SnO2) possesses much higher specific capacity as compared to commercial graphite anode in lithium ion battery (783 vs 372 mAh g(-1)). However, the huge volume change (260%) of SnO2-based anode during the alloying and dealloying process can cause significant electrode pulverization and rapid capacity loss. Herein we report the synthesis of SnO2 asymmetr...

Tin dioxide (SnO2), an n-type semiconductor with a wide band gap of 3.6 eV, has been widely used in photocatalytic degradation of organic dyes, photovoltaic devices, rechargeable lithium batteries, and so on. In particular, remarkable receptivity to variations in gaseous environments and excellent chemical stability have made SnO2 the bestknown gas-sensing material. Over the past decades, consi...

Semiconducting nanoparticle tin oxide-based sensors have been prepared with a pressure load of 4, 6, 8, 10 tons and reinforced with carbon nanofibers (CNF) in SnO2 matrix. The SnO2/CNF sensor’s sensitivity for ethyl alcohol has increased by a factor of two, in compared with that of pure SnO2 8-ton pressed sensor with lower response time. These results open the way towards further optimized lowe...

In this research, Spray pyrolysis technique used to prepared Tin dioxide (SnO2) thin films on glass substrate with thickness about 200± 8 nm by dissolved 2.2563 g of SnCl2.2H2O in 100 ml ethanol then added 60 drops from concentrated hydrochloric acid (HCl). After that the were annealed at different temperatures (300, 400 and °C ). X-ray analyses shows structure all SnO2 is polycrystalline tetra...

One-pot polyol process was combined with metal organic decomposition (MOD) method to fabricate a room-temperature NO2 gas sensor based on tin dioxide and reduced graphene oxide (SO2/RGO) nanocomposite films. X-ray diffractometry (XRD) and scanning electron microscopy (SEM) were used to analyze the structure and morphology of the fabricated films. The electrical and NO2 gas-sensing properties of...

Tin dioxide (SnO2 ) has attracted much attention in lithium-ion batteries (LIBs) due to its abundant source, low cost, and high theoretical capacity. However, the large volume variation, irreversible conversion reaction limit its further practical application in next-generation LIBs. Here, a novel solvent-free approach to construct uniform metal-organic framework (MOF) shell-derived carbon conf...

Atomic layer deposition (ALD) of tin oxide (SnO2) thin films was achieved using a cyclic amide of Sn(II) (1,3-bis(1,1-dimethylethyl)4,5-dimethyl-(4R,5R)-1,3,2-diazastannolidin-2-ylidene) as a tin precursor and nitric oxide (NO) as an oxidant gas. Film properties as a function of growth temperature from 130–250 C were studied. Highly conducting SnO2 films were obtained at 200–250 Cwith the growt...
