From: HRTEM low dose: the unfold of the morphed graphene, from amorphous carbon to morphed graphenes
HRTEM images of carbon soot milled for short times, in a the presence of double-layer graphene and b multi-layer graphenes with up to 5 graphitic layers. The dose rate in use is 197 e−/Å2s for a pixel size of 0.01883 nm and c phase image after exit wave reconstruction procedure. Carbon soot milled for short times, showing the presence of layered graphene parallel and perpendicular to the beam. A focal series of 40 images is used; the dose rate in each case is 55 e−/Å2s for a pixel size of 0.01883 nm. d FFT of phase image in (c). e Measurement of lattice parameters on FFT
