In this paper, we will discuss the methods used to extract the field-effect mobility from the transfer characteristics of organic polymer thin-film . Atomically thin forms of layered materials, such as conducting graphene, insulating hexagonal boron nitride (hBN), and semiconducting molybdenum disulfide (MoS2), have generated great interests recently due to the possibility of combining diverse atomic layers by mechanical “stacking” to create novel materials and devices. In this work, we demonstrate field-effect transistors (FETs) with.

Vanadium dioxide (VO2) is of particular interest due to the fact that the MIT happens in the vicinity of room temperature and it is considered to exhibit the Mott transition. We present a detailed account of our experimental investigation into three-terminal field effect transistor-like devices using thin film VO2 as the channel layer.

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 Author: Miguel Dominguez, Pedro Rosales, Alfonso Torres, Jose A. Luna Lopez, Francisco Flores, Mario Moreno.
An organic field-effect transistor (OFET) is a field-effect transistor using an organic semiconductor in its channel. OFETs can be prepared either by vacuum evaporation of small molecules, by solution-casting of polymers or small molecules, or by mechanical transfer of a peeled single-crystalline organic layer onto a substrate.
These devices have been developed to realize low-cost, large-area. The field-effect transistor (FET) is a type of transistor which uses an electric field to control the flow of are devices with three terminals: source, gate, and control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source.
FETs are also known as unipolar transistors since they involve. The transport properties of 3,ditetradecylpicene ((C 14 H 29) 2-picene) and phenacene thin-film field-effect transistors (FETs) on Si and plastic substrates are reported, in which SiO 2 and parylene are used as gate dielectrics, respectively.
These devices show p-channel normally-off FET characteristics. A μ value of cm 2 V −1 s −1 is obtained in the (C 14 H 29) 2-picene thin. Published in JOURNAL OF APPLIED PHYSICS() 1/30 Three-terminal field effect devices utilizing thin film vanadium oxide as the channel.
The first solid‐state field‐effect transistor has been fabricated utilizing a film of an organic macromolecule, polythiophene, as a semiconductor. The device characteristics have been optimized by controlling the doping levels of the polymer. The device is a normally off type and the source (drain) current can be modulated by a factor of 10 2 –10 3 by varying the gate voltage.

We present a detailed account of our experimental investigation into three-terminal field effect transistor-like devices using thin film VO 2 as the channel layer. The gate is separated from the channel through an insulating gate oxide layer, enabling true probing of the field effect with minimal or no interference from large leakage currents.
A field effect transistor is a three-terminal device in which the current flows along a (n-type or p-type) semiconductor channel contacted between two metal electrodes, the source (S) and the drain (D).
The third electrode is named gate (G) and it is located in close proximity of the channel, forming a. Organic Field Effect Transistors discusses the fundamental mechanisms that apply to OFETs fabrication, operation, and characterization.

Abstract: Thin-film transistors (TFTs), which use zinc oxide (ZnO) as an active layer, were fabricated and investigated in detail. The transport properties of ZnO deposited by spray pyrolysis (SP) on a TFT structure are studied in a wide range of temperatures, electrical conditions (i.e., subthreshold, above-threshold linear, and saturation regions), and at different channel lengths.
The interface between oxide/oxide layers shows an inhomogeneous charge transport behavior, which reveals a high conductivity owing to interface-doped. One typical example is the hetero-interface between ZnO film and other wide band gap oxides (e.g., Al2O3, TiO2, and HfO2).
It is thus quite evident that the ZnO/other oxides hetero-interface contains high density electron carriers effectively. Thin Film Metal-Oxides provides a representative account of the fundamental structure-property relations in oxide thin films.
Functional properties of thin film oxides are discussed in the context of applications in emerging electronics and renewable energy technologies. Readers will find a. Tellurium thin films thermally evaporated at cryogenic temperatures enable the fabrication of high-performance wafer-scale p-type field-effect transistors and three-dimensional circuits.
