Mysteries of atomically thin mica resolved

Mica, a common mineral found in granite, and has been extensively studied from geological, chemical, and technical perspectives. But recently a team from the Vienna University of Technology presented a study that explains the distribution of potassium ions on the mica surface. The researchers used a new type of atomic force microscope to conduct their investigation. Prior to this, the physical surface details of mica have never been studied on an atomic scale.
