Electron Emission Originated from Free-Electron-like States of Alkali-Doped Boron—Nitride Nanotubes.

We investigate the electronic structures and electron emission properties of alkali-doped boron-nitride nanotubes (BNNTs) using density-functional theory calculations. We find that the nearly free-electron (NFE) state of the BNNT couples with the alkali atom states, giving rise to metallic states ne...
