| Popis: | Borophene and the analogs are attractive 2D-materials showing unique mechanical and electronic properties. In this study, the bottom-up synthesis of an atomic boron network possessing a completely planar skeleton was achieved from KBH4. The borophene-analog was stabilized by oxygen atoms positioned on the same plane, providing holes and the anionic state of the layer. Potassium cations between the layers enabled crystalline stacking of the layers, as well as dissolution in solvents as atomically thin layers. The conductivity measurements revealed the electronic feature. Unlike the interplane conducting property, almost zero activation energy like a metal was suggested from the in-plane measurement. |
