Query: Strain Switching in van der Waals Heterostructures triggered by a
  Spin-Crossover Metal Organic Framework   Van der Waals heterostructures (vdWHs) combine different layered materials
with properties of interest,1 such as two-dimensional (2D) semimetals,
semiconductors, magnets or superconductors. These heterostructures provide the
possibility of engineering new materials with emergent functionalities that are
not accessible in another way. Beyond inorganic 2D materials, layered molecular
materials remain still rather unexplored, with only few examples regarding
their isolation as atomically thin-layers. By a proper chemical design, the
physical properties of these systems can be tuned, as illustrated by the
so-called spin-crossover (SCO) compounds, in which a spin transition can be
induced by applying external stimuli like light, temperature, pressure or an
electric field. Here, we report on vdWHs formed by SCO layers and few-layers
graphene, being its properties modified by the strain concomitant to the spin
transition. These molecular/inorganic vdWHs represent the deterministic
incorporation of bistable molecular layers with other 2D materials of interest
in the emergent field of straintronics.
