Ambipolar organic phototransistor
Optical Materials, 2007Abstract We report on the fabrication and characterization of ambipolar organic phototransistors based on amorphous thin films of donor/acceptor dyad N -[7-( N , N -diphenylamino)-9,9′-spirobifluoren-2-yl]- N ′-(2,5-di- tert -butylphenyl)-3,4:9,10-perylenetetracarboxylicdiimide.

On the use of the term “ambipolar”
Applied Physics Letters, 2011The term ambipolar has been used extensively in association with carbon nanotube and graphene-based field effect transistors, often in a varied manner, leading to a confused understanding of the term. Through the use of established scientific definitions and theoretical work on device operation, this paper attempts to clarify the understanding of the ...

Ambipolar Barristors for Reconfigurable Logic Circuits
Nano Letters, 2017Vertical heterostructures based on graphene have emerged as a unique architecture for novel electronic devices with unusual characteristics. Here we report a new design of vertical ambipolar barristors based on metal-graphene-silicon-graphene sandwich structure, using the bottom graphene as a gate-tunable "active contact", the top graphene as an ...

Ambipolar Charge Transport in DNA Molecules
Advanced Materials, 2008The electrical transport properties of DNA films in field‐effect transistor structure are analyzed. As‐depositedfilms did not show electrical conductivity; no DNA network wasobserved between the DNA moleculesbridging the electrodes. When the DNA molecules were stretchedinto a thin film an interpenetratingnetwork formed, and the devicesshowed pronounced

Ambipolar diffusion is a misnomer
Journal of Physics D: Applied Physics, 2003In this paper we examine critically when the term diffusion is an appropriate description of the transport processes occurring in steady state active plasmas. It is suggested that ambipolar flow is a more correct and general expression. The paper examines in detail the situations in: (a) conventional active low temperature electropositive plasmas ...

Ambipolare Diffusion, Diffusionsmoden
1976Bei geladenen Teilchen ist es oft nicht moglich, Driftbewegung und Diffusion getrennt zu betrachten. Da das Feld einer Ladung proportional dem Quadrat des Abstandes a b nimmt, bei homogener Raumerfullung mit Ladungen die Zahl der Ladungen, die mit einer Einzelladung wechselwirken, jedoch proportional der dritten Potenz des Abstandes z u nimmt, sind mit

Ambipolar Charging Responses of Nanoscale Interfaces
ACS Applied Materials & InterfacesLow-dimensional sp2-based carbon nanostructures, known for their remarkable transport properties and mechanical behaviors, are widely used as reinforcing phases in polymer composites to enhance their performance. While carbon nanocomposites are promising materials for extreme conditions, the damage mechanisms due to charge injection at the interfaces ...
