The performance of high-resolution electron microscopy and electron tomography is usually discussed in terms of two-point resolution, expressing the possibility of perceiving separately two image points of an object. However, the concept resolution obtains another meaning if one uses prior knowledge about the object and the imaging procedure in the form of(More)
This paper addresses the question as to what extent the incorporation of a monochromator in an electron microscope can enhance the performance of high resolution transmission electron microscopy (HRTEM). The monochromator will reduce the chromatic aberration, and hence the information limit, at the expense of beam current, leading to a decrease in signal(More)
A quantitative measure is proposed to evaluate and optimize the design of a high-resolution scanning transmission electron microscopy (STEM) experiment. The proposed measure is related to the measurement of atom column positions. Specifically, it is based on the statistical precision with which the positions of atom columns can be estimated. The optimal(More)
In four studies, the authors examined the hypothesis that the way people stereotype is determined by the motives that instigate it. Study 1 measured and demonstrated the effectiveness of a commonly used priming technique to manipulate comprehension and self-enhancement goals. Study 2 demonstrated that why people stereotype determines how they stereotype:(More)
Atomic resolution transmission electron microscopy, even with an aberration free microscope, is only able to resolve and refine amorphous structures at the atomic level for very small foil thicknesses. Then, a precision of the order of 0.01 A is possible, but this may require long recording times, especially for light atoms. For larger thicknesses,(More)
Instrumental developments continue to push the resolution of electron microscopes beyond 1 Å. Apart from the continuous improvement in resolution of the classical high resolution electron microscopes (HREM), new possibilities emerge, such as, correction of the spherical aberration both in transmission and scanning transmission electron microscopy (TEM and(More)
