ecent advances in the synthesis and characterization of
h-BNmonolayersofferopportunitiestotailortheirelectronic
properties via aliovalent substitutions in the two-dimensional
lattice. In this talk, we present a h-BNmonolayer doped with Si,
C or Ge, and show that dopants modify the Fermi level of the
pristine h-BNmonolayer. Three-fold coordinated dopants relax
to the convex-shaped structures, while four-fold coordinated
ones retain the planar structures. The doped structures can be
readily characterized using the STM imaging technique. The
modifications, in turn, lead to unique features in the electron
transport characteristics including significant enhancement
of current at the dopant site, diode-like asymmetric current–
voltage response, and spin-dependent current. We also show
that the spin-polarized transport properties of the doped BN
monolayers could be used for the next-generation devices at
the nanoscale.

T
he automotive industry is widely viewed as being the
industry in which the greatest volume of advanced
composite materials will be used in the future to produce light
vehicles. Nowadays, several advanced materials are widely
used in automotive industry. Because of its multifunctional
properties and promising applications, many expectations
in composite materials are related to graphene. However, no
application of graphene-based materials is currently marketed
in the automotive sector. Therefore, research activities are
under development to study the potentiality of these systems
and all the value’s chain of automotive needs to be involved
in this effort. One of most challenge aims is the economic
impact of the innovative structures on the vehicle market,
all the value’s chain must address their effort to get the
final cost of the innovative products as low as possible. The
present initiative provides a summary overview on graphene
related materials (GRMs) for automotive applications and
investigates efficient ways to integrate graphene as polymer
reinforcements within composite materials for energy-
efficient and safe vehicles (EESVs). The idea is based on the
concept-oriented lightweight design aiming of combination
of light structures with novel multifunctional materials. For
such a purpose, GRMs are addressed with respect to some
challenging factors, for instance the large-scale production
of graphene or the non-existence of constitutive material
models for high performance structural applications like
crashworthiness. Therefore, accurate material models need
to be developed to support simulation of structural design for
these vehicles. A focus on the hierarchical modelling of GRMs
with an emphasis on the multiscale constitutive behaviors
of each material phase is elaborated in the framework of the
graphene flagship to well understand such limitations for a full
applicability of graphene. It is anticipated that this initiative will
advance innovative lightweight graphene nanocomposites and
their related modelling, designing, manufacturing, and joining
capabilities suitable for automotive industry which requires
unique levels of affordability, mechanical performance, green
environmental impact and energy efficiency. This leads to
complete understanding of the newgraphene nanocomposites
and their applicability in high-volume production scenarios.
