Abstract	Two reproducible new phases of 2D boron sheets have been found on Ag(1 1 1). One of them shares the identical atomic structure of the previously reported S1 phase (β 12 sheet) but has a different rotational relationship with the substrate, and thus exhibits very different features in scanning tunneling microscopy (STM) images. The other new phase has a hexagonal symmetry and is proposed to be the long-expected α-sheet. Both of these two boron sheets are confirmed to be metallic by scanning tunneling spectroscopy.

The number of electrons in each of boron's shells is 2, 3 and its electron configuration is [He] 2s² 2p¹. The boron atom has a radius of 90 pm and a Van der Waals radius of 192 pm. Boron was discovered by Joseph Louis Gay-Lussac and Louis Jacques Thénard in 1808 and was first isolated by Humphry Davy later that year. Boron is classified as a metalloid is not found naturally on earth. Elemental Boron Along with carbon and nitrogen, boron is one of the few elements in the periodic table known to form stable compounds featuring triple bonds. Boron has an energy band gap of 1.50 to 1.56 eV, which is higher than that of either silicon or germanium. The name Boron originates from a combination of carbon and the Arabic word buraqu meaning borax.
