Welcome to Physics of Interfaces and Nanomaterials






The PIN-group is led by Prof. Harold Zandvliet and the research field involves controlled preparation and understanding of interfaces, low-dimensional (nano)structures and nanomaterials. We focus on systems that (1) rely on state-of-the art applications or (2) can potentially lead to future applications.

PRL - Knudsen Gas Provides Nanobubble Stability

"Surface nanobubbles are nanoscopic gaseous domains trapped at the solid/liquid interface. They are surprisingly stable to bulk dissolution, questioning the very basics of fundamental physics. We demonstrate that this stability comes because of their nanoscopic size. The bubbles are so small that the gas molecules interact rarely with each ("Knudsen" gas). ... read more

PRL - Anomalous decay of electronically stabilized lead mesas on Ni(111)

Lead that is deposited on metal surfaces tends to spread out like a pancake:
it wets the substrate. Using Low Energy Electron Microscopy we show how
Quantum Size Effects delicately alter the structure of these pancakes. When
the pancakes are heated the tendency to wet is reduced until eventually a
spectacular collapse of the pancakes into spherical droplets is
observed. This transition was visualized directly in the LEEM experiments of Tjeerd Bollmann that have now appeared in the journal Physical Review Letters. ... read more
