Detecting the parity of electron wave functions in solids by quantum-well states of overlayers
New Journal of Physics
We present an approach to monitor the parity of wave functions of electronic states of bulk solids, which was elaborated on the model Ag/W(110) system. The dispersion of quantum-well (QW) states formed in the thin Ag layer was examined by means of angle-resolved photoemission. The obtained experimental data were compared with results of layer Korringa-Kohn-Rostoker calculations. We found that around k points, where the two-dimensional QW bands cross the projected bulk bands of the W substratedoi:10.1088/1367-2630/10/4/043038 fatcat:gjm62vadmzen5n4u5f7nj6y2om
