Image formation in a transmission electron microscope equipped with an environmental cell: Single-walled carbon nanotubes in source gases

We have outlined a theory of image formation in a transmission electron microscopy equipped with an environmental cell (E-TEM). We have applied the outlined theory to simulating high-resolution transmission electron microscopy (HRTEM) images of single-walled carbon nanotubes (SWNT's) in source gases of ethanol at the actual growth condition: the pressure and the temperature of ethanol gas are equal to 5 Torr and 800 degrees C, respectively. It is noteworthy that the growth process can be reproduced in E-TEM's. We have suggested that the diameter and chirality of SWNT's are most likely determined in a Fourier transform of HRTEM images.
