Raman spectra taken at different positions of an h-BN bubble. a AFM image of a typical h-BN bubble; the white curve shows the profile across the center of bubble and gives information about its height and diameter. Scale bar, 600 nm. b Raman spectra taken at the positions indicated in the AFM image. The inset shows the variation in the E2g peak position and FWHM between positions. A redshift in the E2g peak position from the flat area to the center of the bubble is observed, while the corresponding FWHM is nearly unchanged
