(left) Experimental momentum maps of PTCDA on MgO(001) at increasing photon energy. The pattern changes with photon energy as a result of the bent carbon backbone of PTCDA. (right) Side view in real space and three-dimensional momentum space density of the calculated highest occupied molecular orbital of PTCDA on MgO(001). The grey sphere represents the cut through the 3D momentum space density at a certain photon energy, which is measured experimentally as 2D momentum map. Image: UniGraz/Sterrer

POT detects molecular bend

Photoemission-Orbital-Tomography detects the bend of the molecular backbone of a Pi conjugated molecule upon adsorption on a MgO surface.
The scientists were able to induce organized growth of organic molecules on metal surfaces and to control the morphism of resulting structures. (Image: Uni Graz/Boné)
