The experimental results confirm earlier predictions using first principle calculations. (sciencedaily.com)
The work has gained wide acceptance since its publication in Nature two years ago, especially since their first principles calculations now have some experimental backing. (discovermagazine.com)
First - principles calculations determined that the electron barrier, established at the interface of the PEI / hexagonal boron - nitride structure and the metal electrodes applied to the structure to deliver, current is significantly higher than typical metal electrode - dielectric polymer contacts, making it more difficult for charges from the electrode to be injected into the film.
