What is the best substrate for exfoliating few layers of hexagonal boron nitride (hBN) using traditional scotch tape method?

Unlike graphene, it is usually very difficult to exfoliate few layers (~10 nm thick) of hBN on SiO2 substrate due to lip-lip interaction at the edges. Au substrates have been proven very useful...
