Abstract

In article number 1800072, Josué J. López and co-workers use photothermal microscopy to measure the near-field absorption of nanostructured hexagonal boron nitride (h-BN) and reveal a large photothermal expansion in the nanostructures. This effect is attributed to the anisotropy of the thermal expansion coefficients of h-BN and the nanostructuring implemented. The photothermal expansion should be present in other van der Waals materials and may lead to nanomechanical switches driven by light.
