Room temperature progress of two-dimensional van der Waals (2D-vdW) supplies is indispensable for state-of-the-art nanotechnology because it supersedes the requirement of elevated progress temperature accompanied with extra excessive thermal budgets, and the opportunity of intrinsic interfacial thermal diffusion associated deterioration of purposeful properties. Right here, we demonstrated the expansion of ultrawide-bandgap boron nitride (BN) at room temperature through the use of the pulsed laser deposition (PLD) course of and demonstrated varied functionalities for potential functions. Complete chemical, spectroscopic and microscopic characterization confirms the expansion of ordered nano-sheet-like hexagonal BN (h-BN). Functionally, nanosheets present hydrophobicity, excessive lubricity (low coefficient of friction), low refractive index inside the seen to near-infrared wavelength vary, and room temperature single-photon quantum emission. Our work unveils an essential step that brings a plethora of functions starting from the exact design of photonic units, quantum data know-how, clear lubricant coatings, chemically inert capping layers for corrosive and ambient-air degradable supplies, and 2D versatile nano-electronics, thus making a situation for “h-BN on demand” at frugal thermal finances.
