Temperature Gradient Effect on Gas Discrimination Power of a Metal-Oxide Thin-Film Sensor Microarray

The paper presents results concerning the effect of spatial inhomogeneous operating temperature on the gas discrimination power of a gas-sensor microarray, with the latter based on a thin SnO2 film employed in the KAMINA electronic nose. Three different temperature distributions over the substrate are discussed: a nearly homogeneous one and two temperature gradients, equal to approx. 3.3 C/mm a...

Metal-Semiconductor Interfaces in Thin-Film Transistors

The metal-semiconductor interface in thin-film transistors (TFTs) is one of the bottlenecks on the development of these devices. Although this interface does not play an active role in the transistor operation, a low-quality interface can be responsible for a low performance operation. In a-Si TFTs, a doped film can be used to improve this interface, however, in other TFT technologies, there is...

Organic Semiconductor Nanoparticle Film: Preparation and Application

Complementary Metal–Oxide–Semiconductor Thin-Film Transistor Circuits From a High-Temperature Polycrystalline Silicon Process on Steel Foil Substrates

We fabricated CMOS circuits from polycrystalline silicon films on steel foil substrates at process temperatures up to 950 C. The substrates were 0.2-mm thick steel foil coated with 0.5m thick SiO2. We employed silicon crystallization times ranging from 6 h (600 C) to 20 s (950 C). Thin-film transistors (TFTs) were made in either self-aligned or nonself-aligned geometries. The gate dielectric wa...
