Figure 4
cSTXM micrographs of AgTCNQ crystals from transmission geometry (710 eV, 120 × 120 pixel, 30 ms dwell time). (a) Small AgTCNQ crystals lying on a rhombic TCNQ crystal (white circle) are in good focus, while the large AgTCNQ crystal in the lower left corner (black circle) is slightly defocused. (b) Sample shift of 4 µm along the optical axis moves the large crystal into proper focus, while the small crystals are slightly defocused. |
