This light microscope image shows few layers of molybdenum disulfide (MoS2), a layered crystal held together by van der Waals forces, on a thin gold film. These very thin MoS2 flakes were made by cleaving the natural layered bulk crystal, with the gold film serving as a stabilizer. The color of the flakes indicates the thickness of the flakes. The light orange to yellow regions are only a few to a single atom layer thin.
