Measuring electron wave functions of lateral nanostructures by means of photoemission. Angle-resolved photoemission is unique to thorougly probe electron wave functions in reciprocal space. Since the probabilitiy density is the physical observable, direct Fourier transformation to real space is lacking phase information. However, in nanostructures grown on a surface, such as dots, wires or stripes, the wave functions are confined laterally and hence phase retrieval iterative procedures can be applied. In fact, using electron surface states confined to terraces on stepped surfaces, we have shown that is possible to recover electron wave frunctions in real space directly from photoemission data, applying the oversampling method of x-ray diffraction.
