Query: Electrical sensing of the thermal and light induced spin transition in
  robust contactless spin-crossover/graphene hybrid devices   Hybrid devices based on spin-crossover (SCO)/2D heterostructures grant a
highly sensitive platform to detect the spin transition in the molecular SCO
component and tune the properties of the 2D material. However, the fragility of
the SCO materials upon thermal treatment, light irradiation or contact with
surfaces and the methodologies used for their processing have limited their
applicability. Here, we report an easily processable and robust SCO/2D hybrid
device with outstanding performance based on the sublimable SCO [Fe(Pyrz)2]
molecule deposited over CVD-graphene, which is fully compatible with
electronics industry protocols. Thus, a novel methodology based on growing an
elusive polymorph of [Fe(Pyrz)2] (tetragonal phase) over graphene is developed
that allows us to electrically detect a fast and effective light-induced spin
transition in the devices (~50% yield in 5 minutes). Such performance can be
enhanced even more when a flexible polymeric layer of PMMA is inserted in
between the two active components in a contactless configuration, reaching a
~100 % yield in 5 minutes.
