We demonstrate, by using solution-processed field-effect transistors, that hole transport and electron transport are both generic properties of organic semiconductors. This ambipolar transport is ...

active materials that should sustain ambipolar field-effect transport and efficient electroluminescence emission; (iii) dieletric surfaces that should be trap-free to favour effective mobility of ...

A drop in electric potential of just 0.55 V measured at altitudes of between 250–768 km in the Earth’s atmosphere above the North and South poles could be the first direct measurement of our planet’s ...

Considering the ionosphere is responsible for shielding us surface-dwelling mammals from the cancer-causing effects of solar ...

this suggests that although the ambipolar field aids in increasing the altitude and density of the ions in Earth’s atmosphere, a major effect should be expected on Earth’s ionosphere. For instance, ...

By employing the standard microfabrication techniques used, for instance, in manufacturing of computer chips, the team demonstrated an ambipolar field-effect transistor, which works under ambient ...

“The net effect of the ambipolar field is to extend the height of the atmosphere, lifting some ions high enough to escape with the polar wind,” NASA said. “It’s like this conveyor ...

Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is ...

The field, known as the ambipolar electric field, was discovered by NASA's suborbital Endurance rocket more than 60 years after it was first hypothesized, and is thought to be as fundamental to ...

This "ambipolar electric field" is a weak electrical field covering the entire planet, and was first theorized to exist over 60 years ago, but has finally been detected thanks to observations from ...
