报告摘要：Atomically thinhexagonal boron nitride(BN) possess some characters similar to graphene butalso many unique properties unavailable to its carbon counterpart. In contrastto the intensive studies and wide publicity of graphene, many fundamentalproperties and potential applications of these BN nanomaterials are not clear.Atomically thin BN has been one of the focuses of my research. We invented thefirst large-scale synthesis route of BN sheets. The fundamental physicalproperties of the material have been systematically studied. We find thathigh-quality single-crystalline mono- and few-layer BN nanosheets are one ofthe mechanically strongest and most thermally conductive electricallyinsulating materials. We use both experiment and simulation to reveal theintrinsic dielectric screening, phonon dispersion, and Raman signature ofatomically thin BN of different thicknesses. It is also found that atomicallythin BN as an adsorbent experiences conformational changes upon surfaceadsorption of molecules, increasing adsorption energy and efficiency. The deepultraviolet light emission from BN sheets is also investigated. Thanks to theseexciting properties, atomically thin BN has strong potential to solvechallenges in different fields, such as corrosion protection, ultra-sensitivesensing, lubrication, and thermal management.
