Development of “paper transistors” with new structure using carbon-nanotube-composite papers for aiming to construct logic circuits

Iijima R., Oya T., Yokohama National University, JP

We propose new “paper transistors” with unique structure using carbon-nanotube (CNT)-composite papers for aiming to construct “paper logic circuits.” Recently, the CNT that is one of nano-carbon materials has been receiving increasing attention because it [...]

Transparent, Scalable, and Flexible Piezoelectric Pressure Sensors

Vishniakou S., UC San Diego, US

We present a pressure-sensitive ZnO thin-film transistor (TFT) as a potential technology for next-generation touchscreen. We discuss the properties of our devices and propose a structure that could be used to create transparent, scalable, and [...]

Temperature Stability of PAG-Doped-Graphene, Towards Commercial Production of Graphene Integrated Circuits

Al-Mumen H., Li W., Michigan State University, US

In our previous work we found out a highly in air stable technique, defect-less, and relatively high electron mobility for n-doping graphene nanomesh using PAG (an element of SU-8 resist compound). This work demonstrated the [...]

Thin film transistors with printed semiconductive oxide channel and silver source-drain electrodes

Chen Z., Cui Z., Suzhou Institute of Nano-tech and Nano-bonic, Chinese Academy of Sciences, CN

In order to make all-printed thin-film transistors, the key issue such as the interfacing effect between printed electrodes and printed semiconductive channel layer has to be solved.In this study, thin film transistors were fabricated by [...]

Innovative Gas Sensors for Sub-ppm Detection of Organophosphorus Nerve Agents by Chemically Functionalized Carbon Nanotube Field-Effect Transistors

Carella A., Caillier L., Clavaguera S., Celle C., Simonato J-P, CEA, FR

In this communication, we will present innovative sensors based on carbon nanotube field-effect transistors (CNT-FET) for detection of organophosphorus agents (OP, Sarin-like molecules). We have functionalized CNT with organic moieties reactive towards OPs that form [...]

What is a Transistor?

Sah C., Jie B., University of Florida, US

After 75 years of learning vacuum tube and solid state electronics in three human generations, we now come to the end of the complete understanding of what is a transistor. It is far beyond, eight [...]

Silicon Nanowire Transistors Fabricated by the Mass-Manufacturable, Self-Assembling “Grow-in-Place” Approach

Shan Y., Fonash S.J., Pennsylvania State University, US

Silicon nanowire (SiNW) transistor fabrication, until our work, has had environmental concerns and manufacturing issues arising from the use of a complex process flow involving SiNW growth and harvesting followed by nanowire positioning, aligning and [...]

N-channel Single Crystal Si Nanoparticle Schottky Barrier Transistor

Song S.H., Ding Y., Kortshagen U., Bapat A., Campbell S.A., University of Minnesota, US

A novel process has been developed by when large (~40 nm) cubic single crystals of silicon can be produced at high rates. In a previous paper we demonstrated that these particles can be used to [...]

Single-Crystal Nanowire Transistor for Logic and Memory Applications

Yu B., Ye L., Meyyappan M., NASA Ames Research Center, US

In this paper we report chemical synthesis, device fabrication, and device physics investigation of 1-D single-crystalline nanowire field-effect transistor (SNW-FET) for logic and memory applications. Wafer-scale transistor arrays were fabricated with semiconducting nanowires serve as [...]

Room-Temperature InAlAs/InGaAs Planar Tunneling-coupled Transistor

Moon J-S., Rajavel R., Chow D., Bui S., Wong D., HRL Labs, US

In this talk, we report the first experimental demonstration of InAlAs/InGaAs planar tunneling-coupled transistors at room temperature, in which tunneling characteristics such as negative differential resistance (NDR) and peak current are controlled with high gain [...]
