Here we present synthesis and electronic properties of a new alternating copolymer composed of dithieno[2,3-d;2',3'-d']benzo[1,2-b;4,5-b']dithiophene (DTBDT) and diketopyrrolopyrrole units, poly dithienobenzodithiophene-co-diketopyrrolopyrrolebithiophene (PDPDBD). The resulting polymer showed hysteresis free, fast switching and highly reliable organic thin-film transistor properties comparable ...

By electrochemically p-doping pentacene in the vicinity of the source-drain electrodes in organic field effect transistors the injection barrier for holes is decreased. The focus of this work is put on the influence of the p-doping process on the transistor performance. Cyclic voltammetry performed on a pentacene based transistor exhibits a reversible p-doping response. This doped state is evok...

Solid–Liquid Phase Transitions In article number 2300542, Franklin Liou, Hsin-Zon Tsai, Alex Zettl, Johannes Lischner, Michael Crommie, and co-workers use scanning tunneling microscopy to image a solid–liquid phase transition with sub-nanometer spatial resolution at the surface of graphene field-effect transistor. They electrostatic gating drive reversible transitions between quasi-1D molecular...

The Anderson-Holstein model with Caldeira-Leggett coupling with environment is considered to describe the damping effect in a single molecular transistor (SMT) which comprises a molecular quantum dot (with electron-phonon interaction) mounted on a substrate (environment) and coupled to metallic electrodes. The electron-phonon interaction is first eliminated using the Lang-Firsov transformation ...

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...

Electrostatic carrier injection into insulating molecular conductors has been examined by fabricating field effect transistor structure in two kinds of procedures. One procedure employed a direct growth of the organic single crystals by electrochemical reaction on platinum electrodes deposited on the gate dielectric. In the other procedure very thin crystals were laminated on the substrate in e...

This paper presents a new design for 14 transistor single bit full adder, implemented using five transistor XNOR/XOR cell and transmission gate multiplexer. For transmission gate multiplexer complementary gate control signals are required and in 14 transistor full Adder both XOR and XNOR signals are generated. XNOR/XOR cell shows high power consumption than single XNOR gate. So, 8 transistor fu...
