The electronic and optical properties of 2D hexagonal boron nitride are studied using first principle calculations. GW and BSE methods are employed in order to predict with better accuracy the excited and excitonic properties of this material. We determine the values of the band gap, optical gap, excitonic binding energies and analyse the excitonic wave functions. We also calculate the exciton energies following an equation of motion formalism and the Elliot formula, and find a very good agreement with the GW +BSE method. The optical properties are studied for both the TM and TE modes, showing that 2D hBN is a good candidate to polaritonics in the UV range. In particular it is shown that a single layer of h-BN can act as an almost perfect mirror for ultraviolet electromagnetic radiation. arXiv:1807.06413v1 [cond-mat.mes-hall]

“…Two-dimensional (2D) materials, e.g. graphene (with κ up to ~5300 Wm -1 K -1 ) and hexagonal boron nitride h-BN (with κ up to ~200 Wm -1 K -1 to ~500 Wm -1 K -1 ), are believed to be potential candidates for efficient heat removal due to their high in-plane thermal conductivity [2][3][4][5][6][7][8][9][10][11].…”

The needs for efficient heat removal and superior thermal conduction in nano/micro devices have triggered tremendous studies in low-dimensional materials with high thermal conductivity. Hexagonal boron nitride (h-BN) is believed to be one of the candidates for thermal management and heat dissipation due to its novel physical properties, i.e. thermal conductor and electrical insulator. Here we reported interfacial thermal resistance between few-layer h-BN and its silicon oxide substrate using differential 3ω method. The measured interfacial thermal resistance is around ~1.

“…The c‐ BN, due to its hardness, can be used as an abrasive material. While the excellent electrical resistivity of and thermal conductivity of BN makes the use for heat spreaders, the exfoliated hexagonal nanosheets can enhance the thermal conductivity of polymer materials . Other scientific fields where h‐ BN‐based materials can be found involve electrochemistry, biosensing, and even antibacterial properties .…”

Hexagonal and Cubic Boron Nitride in Bulk and Nanosized Forms and Their Capacitive Behavior

Two‐dimensional materials have attracted due to their remarkable optical, electrical, and chemical properties in different crystalline forms. Hexagonal and cubic boron nitride (BN) and their nanostructured forms are compared in respect to their capacitive behavior in different electrolytes. We found that hexagonal BN nanosheets exhibited the highest gravimetric capacitance compared with its bulk and with the cubic BN (bulk and nanosheets) counterpart. The higher capacity originates from the larger surface of nanosized sample and is related to it crystal structure as well. These materials can be beneficial in energy storage applications when forming electrode of supercapacitors, where high energy density is required.
