This article discusses the main uses of 1D and 2D nanomaterials in the development of
conductometric gas sensors based on metal oxides. It is shown that, along with the …

Engineering approaches designed to improve parameters of conductometric gas sensors
are being considered in this survey. In particular, in this paper we have analyzed …

Schottky barriers (SBs) are often formed at the semiconductor/metal contacts and affect the
electrical behavior of semiconductor devices. In particular, SBs are playing a major role in …

We report on studies of field-effect transistor (FET) and transparent thin-film transistor (TFT)
devices based on lightly Ta-doped SnO2 nano-wires. The nanowire-based devices exhibit …

We report highly facet-dependent electrical properties of Cu2O nanocubes and octahedra
and significant enhancement of gold nanocrystal cores to the electrical conductivity of Au …

Novel SnO2− In2O3 heterostructured nanowires were produced via a thermal evaporation
method, and their possible nucleation/growth mechanism is proposed. We found that the …

We demonstrate that illuminating metal oxide gas sensors with ultra-violet light is a viable
alternative not only to activate but also to modulate their response towards oxidizing gases …

Dissipated power in metal oxide nanowires (r NW< 45 nm) often causes important self-
heating effects and as a result, undesired aging and failure of the devices. Nevertheless, this …

The responses of individual ZnO nanowires to UV light demonstrate that the persistent
photoconductivity (PPC) state is directly related to the electron–hole separation near the …

This work reports on the gas sensor response of undecorated 1D stannous oxide nanobelts
and those decorated with Pt and Pd nanoparticles. The sensor device responses to H 2, CO …
