Bright-field TEM imaging of single molecules: Dream or near future?

“…From the illustrative model discussed in our paper, it appears that the best TEM for imaging iodine-substituted single molecules is one with high electro-optical brightness b operated at low U 0 equipped with a correction of spherical aberration of the imaging system [35]. Taking into account the current technology available for electron sources, this argues for an instrument operated below 100 kV equipped with coldfield-emission gun.…”
