The combination of their electronic properties and dimensions makes carbon nanotubes ideal building blocks for molecular electronics. However, the advancement of carbon nanotube-based electronics requires assembly strategies that allow their precise localization and interconnection. Using a scheme based on recognition between molecular building blocks, we report the realization of a self-assemb...

Novel type of a field effect transistor (FET) is described. A metallic channel of a metallic nanotube FET is proposed to be switched ON/OFF by applying electric fields of a local gate. Very inhomogeneous electric fields may lower the nanotube symmetry and open a band gap, as shown by tight–binding calculations.

We numerically investigate the possibility of using Tunnel field-effect transistor (TFET) in a 32 kHz crystal oscillator circuit to reduce power consumption. A simulation using SPICE (Simulation Program with Integrated Circuit Emphasis) is carried out based on a conventional CMOS transistor model. It is shown that the power consumption of TFET is one-tenth that of conventional low-power CMOS.

Organic Thin Film Transistors (OTFT), gated through an aqueous electrolyte, have extensively been studied as sensors in various applications. These water-gated devices are known to work both as electrochemical (Organic ElectroChemical Transistor OECT) and field-effect (Organic Field-Effect Transistor OFET) devices. To properly model and predict the response of water-gated OTFT sensors it is imp...

was readily constructed by simple modification of a common FID hydrocarbon monitor, with addition of a commercially available valve oven, switching valve, and timer. This system, except for the adjusted response time, had virtually the same operating specifications as the original hydrocarbon analyzer. Short-term studies indicated the system was practical, reliable, and accurate. Air-monitoring...

In nature, electrical signalling occurs with ions and protons, rather than electrons. Artificial devices that can control and monitor ionic and protonic currents are thus an ideal means for interfacing with biological systems. Here we report the first demonstration of a biopolymer protonic field-effect transistor with proton-transparent PdH(x) contacts. In maleic-chitosan nanofibres, the flow o...

In a collinear antiferromagnet with easy-axis anisotropy, symmetry dictates that the spin wave modes must be doubly degenerate. Theses two modes, distinguished by their opposite polarization and available only in antiferromagnets, give rise to a novel degree of freedom to encode and process information. We show that the spin wave polarization can be manipulated by an electric field induced Dzya...

Diamond Junction Field Effect Transistor Ultrawide bandgap semiconductors offer a new playground for researchers thanks to their huge energy scale. In article 2100542, Julien Pernot and co-workers create diamond junction field effect transistor from non-volatile photo-switch by taking advantage of the deep ionisation nitrogen donor in n-type region. The state can only be switched under illumina...

Carbon nanomaterials field-effect transistor (FET)-based electrical biosensors provide significant advantages over the current gold standards, holding great potential for realizing direct, label-free, real-time electrical detection of biomolecules in a multiplexed manner with ultrahigh sensitivity and excellent selectivity. The feasibility of integrating them with current complementary metal ox...

The Field Effect Transistor using nanotechnology is known as Carbon Nanotube Field Effect Transistors (CNTFET). Which promising nano-scaled devices for implementing high performance very dense and low power circuits. A Carbon Nanotube Field Effect Transistor refers to a FET with a single CNT or an array of CNT's as the channel material instead of bulk silicon in the traditional MOSFET structure...
