The mission of 2D Materials Engineering is to synthesize, investigate, and tailor two-dimensional materials and their heterostructures to pave the way for a new era of transparent and flexible technology. The discovery of graphene has led to a resurgence of interest in other two-dimensional materials, and an ever-growing portfolio of atomic sheets, (such as transition metal dichalcogenides (TMDs), hexagonal boron nitride (h-BN) and layered oxides) is being actively theoretically and experimentally studied. Van der Waals heterostructures are built much like “Lego” at an atomic-scale, by vertically stacking 2D layered materials.
Today we can envision flexible and transparent electronic devices with an h-BN dielectric, a TMD semiconductor and graphene electrodes. Devices such as these would have been considered science fiction only a few years ago, but today are within reach. Opportunely designed material stacks are expected to exhibit unprecedented electronic, optical and magnetic properties.
We synthesize via chemical vapour deposition (CVD) highly-crystalline 2D materials and their heterostacks and adopt advanced microscopy and spectroscopy techniques for investigating their fundamental properties. We tailor the structural, electronic, and optical properties of layered materials by devising and implementing different functionalization and intercalation approaches. Our ultimate goal is to realize a new class of all-2D flexible and transparent devices.

While developing her research line, Camilla Coletti also works within the CNI@NEST Pisa.
