“…However, increased interlayer interaction in hexagonal boron nitride (h-BN) compared to graphite is thought to limit intercalation (Altintas et al, 2011). This hypothesis is consistent with results from other studies that have demonstrated reduced carbon oxidation at elevated temperatures of boron nitride doped graphite relative to unmodified graphite (Shen et al, 1999;Dai and Zhang, 2002), suggesting that movement of oxygen between layers is restricted.…”

This paper reports on characterization techniques for electron emission from potassiumintercalated boron nitride-modified graphitic petals (GPs). Carbon-based materials offer potentially good performance in electron emission applications owing to high thermal stability and a wide range of nanostructures that increase emission current via field enhancement. Furthermore, potassium adsorption and intercalation of carbon-based nanoscale emitters decreases work functions from approximately 4.6 eV to as low as 2.0 eV. In this study, boron nitride modifications of GPs were performed. Hexagonal boron nitride is a planar structure akin to graphene and has demonstrated useful chemical and electrical properties when embedded in graphitic layers. Photoemission induced by simulated solar excitation was employed to characterize the emitter electron energy distributions, and changes in the electron emission characteristics with respect to temperature identified annealing temperature limits. After several heating cycles, a single stable emission peak with work function of 2.8 eV was present for the intercalated GP sample up to 1,000 K. Up to 600 K, the potassium-intercalated boron nitride modified sample exhibited improved retention of potassium in the form of multiple emission peaks (1.8, 2.5, and 3.3 eV) resulting in a large net electron emission relative to the unmodified graphitic sample. However, upon further heating to 1,000 K, the unmodified GP sample demonstrated better stability and higher emission current than the boron nitride modified sample. Both samples deintercalated above 1,000 K.

“…Although experimental results indicate that some chemical elements are indeed intercalated into h-BN [9][10][11], the fundamental properties of the compounds remain unclear yet. Thus, based on the analogy with GICs, the hybrid structure of h-BN and atoms that are intercalated into the interlayer spacing may also exhibit interesting electronic properties because the lower unoccupied electronic structure of h-BN is similar to that of graphite.…”

By using the local density approximation in density functional theory, we study the electronic structure of hexagonal boron nitride (h‐BN) intercalation compounds in which lithium atoms are intercalated into the interlayer spacing. We find that the electronic structure of lithium‐intercalated h‐BN under equilibrium interlayer distance is metallic, in which electrons are injected into a nearly free electron state. The calculated Fermi surfaces of the compound possesses circular shape around the Γ point and are similar to that of alkali/alkali‐earth metal‐doped graphite intercalation compounds (GICs) (© 2011 WILEY‐VCH Verlag GmbH & Co.
