We demonstrate, via scanning tunneling microscopy (STM) measurements performed at 48 K, the existence of “bright beaches” at the edges of K islands (diameter ∼ 5 – 500 nm ) on the graphite surface. The enhanced tunneling current is only observed in monolayer-high islands on graphite, and not in islands of similar geometry on top of a K monolayer film. First-principles density functional calculations and STM simulations suggest that this is an STM field effect, which appears as the positive tip attracts donated electrons back to the metallic K islands. The restored charge accumulates preferentially at the island edges.

Almost one century of forest inventory data: how bright are the prospects for the Finnish forest biodiversity? Fayt, Philippe (Open Science Centre, University of Jyväskylä, 2018)With 73% forest cover and 26.2 million ha of forestry land, Finland is the most forested country in Europe, hence contributing significantly to its forest biodiversity. The forestry land is classified into forest land (20.3 ...
