From: Three-dimensional electron ptychography of organic–inorganic hybrid nanostructures

a, b Normalised ptychographic phases at accelerating voltages of 60 and 300 kV, respectively. c, d Normalised representative TEM images (from a set of typically 20 recorded) at accelerating voltages of 60 and 300 kV, respectively. e–h Frequency histograms of the images a–d, respectively.
