| Imaging Details | K2 SUMMIT DIRECT DETECTOR DEVICE (GATAN INC.) OPERATED IN SUPER-RESOLUTION MODE WITH A 1.64 ANGSTROM PHYSICAL PIXEL AND 0. 82 ANGSTROM SUPER- RESOLUTION PIXEL. WITH NO SPECIMEN PRESENT, THE RATE OF EXPOSURE OF THE DETECTOR WAS 8 ELECTRONS PER PIXEL PER SECOND. EXPOSURE- FRACTIONATED MOVIES OF 20.1 S WERE RECORDED AS STACKS OF 67 FRAMES, SO THAT SELECTED SPECIMEN AREAS WERE EXPOSED WITH A TOTAL OF 60.3 ELECTRONS PER SQUARE ANGSTROM. |
