Chemical vapor deposition growth and transfer of two-dimensional hexagonal boron nitride

Atomically thin two-dimensional (2D) hexagonal boron nitride (h-BN) exhibits many attractive properties such as high thermal conductivity, stability, high mechanical performance, good electrical insulator which is also chemically inert and resistant to corrosion. This report consist of literature re...
