Here, we demonstrated the growth of ultrawide-bandgap boron nitride (BN) at room temperature by using the pulsed laser deposition (PLD) process and demonstrated various functionalities for potential applications. Comprehensive chemical, spectroscopic and microscopic characterization confirms the growth of ordered nano-sheet-like hexagonal BN (h-BN). Functionally, nanosheets show hydrophobicity, high lubricity (low coefficient of friction), low refractive index within the visible to near-infrared wavelength range, and room temperature single-photon quantum emission. Our work unveils an important step that brings a plethora of applications ranging from the precise design of photonic devices, quantum information technology, transparent lubricant coatings, chemically inert capping layers for corrosive and ambient-air degradable materials, and 2D flexible nano-electronics, thus creating a scenario for “h-BN on demand” at frugal thermal budget.
