DOI: 10.1021/jacs.0c07173
Abstract: Rational design and fabrication of graphene nano-architectures with multifunctionality and multidimensionality remains quite a challenge. Here, we present a synthetic sequence, based on the combination of two advanced patterned-functionalization principles, namely, laser-writing and poly(methyl methacrylate)… read more here.

DOI: 10.1063/1.5081750
Abstract: The lack of bandgap in graphene is the main factor that prevents that this outstanding material be implemented in optoelectronics. In this work, we show that by nanostructuring graphene aperiodically it is possible to have… read more here.

DOI: 10.1103/physrevb.96.075409
Abstract: We propose and theoretically explore states of graphene superlattices with relaxed P and T symmetries created by strong circularly polarized ultrashort pulses. The conduction-band electron distribution in the reciprocal space forms an interferogram with discontinuities… read more here.

DOI: 10.1103/physrevlett.121.026806
Abstract: We report the experimental observation of commensurability oscillations (COs) in 1D graphene superlattices. The widely tunable periodic potential modulation in hBN-encapsulated graphene is generated via the interplay of nanopatterned few-layer graphene acting as a local… read more here.

DOI: 10.1103/physrevlett.130.186204
Abstract: Recent studies of van der Waals (vdW) heterostructures and superlattices have shown intriguing quantum phenomena, but these have been largely explored only in the moderate carrier density regime. Here, we report the probe of high-temperature… read more here.
