Abstract

original image

Malen nach Feldern: Das elektrische Feld einer Rastertunnelmikroskopspitze (links) steuert die Diffusion von Wasserstoff an einer Palladiumoberfläche, sodass charakteristische Muster resultieren. Das STM-Bild (rechts) zeigt einen dreieckigen Bereich mit niedriger Wasserstoffkonzentration, umgeben von weißen Bereichen, die von Wasserstoff unter der Oberfläche herrühren.
