Description

Overview

This repository contains 2 example 4D-STEM datasets format from the paper "Phase Object Reconstruction for 4D-STEM using Deep Learning". The data was written to hdf5 for compatibility with the python programming language. When reading from these files consider possibly different storage conventions (Row major vs. column major format). Data may need to be transposed accordingly.

 

Parameters

The twisted bilayer graphene dataset is simulated. The smaller file is an experimental SrTiO3 dataset.
