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...

Do the introduced salts (NaOH/ HCl) influence the spectroscopic shifts of the fluorescence excitation-emission matrix?

During the resin (XAD-8) fractionation of wastewater salts (NaOH or HaCl) are used for acid or base elutions/pH adjustments. Since the amount of introduced salt is minimal, so is it required to...

How the Ground Plane implantation is performed without damaging (and w/o varying the undoped nature) the top Si (8-10 nm) in FDSOI technology ?

It is a general practice to introduce Ground Plane in FDSOI devices under the BoX. The Ground Planes are introduced by Ion Implantation through Top Si layer and Buried Oxide. I wanted to know that...
