Physics
(For the case of the hexagonal boron nitride and tungstendiselenide, show your physics reasoning on why there is a shift inthe phonon mode as the thickness of the materials reduces?)
If thickness of material lattice is reduced , the raman shiftincreases. So, there is shift in phonon mode as the thickness ofmaterials reduces.
can someone please explain the physics reasoning of thisstatement
