Integrated Differential Phase Contrast (iDPC) – Direct Phase Imaging in STEM for Thin Samples
نویسندگان
چکیده
Imaging the phase of the transmission function has always been the ultimate goal of any (S)TEM imaging technique as it is, for thin samples, directly proportional to the projected potential in the sample. Customarily this information is obtained using Holography [1] or by performing focus series reconstruction in TEM (FSR-TEM) [2], recently also in combination with Phase Plates (PP) [3] and/or image Cs correction. Ptychographic reconstruction has also been considered as an alternative [4].

Integrated Differential Phase Contrast (iDPC) STEM: A New Atomic Resolution STEM Technique To Image All Elements Across the Periodic Table
A new, recently introduced Integrated Differential Phase Contrast (iDPC) STEM imaging technique [1] is enabling live imaging of the phase of the transmission function of thin samples. One of the first striking advantages of this new technique is that it is able to image light (C, O, N ...) and heavier elements (Sr, Ti, Ga ...) together in one image whereas a standard (HA)ADF-STEM image shows on...
متن کاملPhase contrast scanning transmission electron microscopy imaging of light and heavy atoms at the limit of contrast and resolution
Using state of the art scanning transmission electron microscopy (STEM) it is nowadays possible to directly image single atomic columns at sub-Å resolution. In standard (high angle) annular dark field STEM ((HA)ADF-STEM), however, light elements are usually invisible when imaged together with heavier elements in one image. Here we demonstrate the capability of the recently introduced Integrated...
متن کاملPixelated detectors and improved efficiency for magnetic imaging in STEM differential phase contrast.
The application of differential phase contrast imaging to the study of polycrystalline magnetic thin films and nanostructures has been hampered by the strong diffraction contrast resulting from the granular structure of the materials. In this paper we demonstrate how a pixelated detector has been used to detect the bright field disk in aberration corrected scanning transmission electron microsc...
