Modeling superconducting vortices in high-T-c materials for TEM observations

In order to improve the model for the interpretation of transmission electron microscopy images of superconducting vortices in layered materials the number of representative layers should be increased. The upper limit of nine layers related to the computer performance has been more than doubled by approximating the screening layers above and below the layer containing a pancake vortex with a superconducting continuum.
