Buckled two-dimensional Xene sheets

Silicene, germanene and stanene are part of a monoelemental class of two-dimensional (2D) crystals termed 2D-Xenes (X = Si, Ge, Sn and so on) which  may open new reserach frontiers in science at the nanoscale and nanotechnology.  The Perspective proposed by Alessandro Molle (CNR-IMM) et al. on Nature Materials 16, 163 (2017) highlights the current state of the art and future opportunities in the manipulation and stability of these materials, their functions and applications, and novel device concepts.

The activity is focussed on the design and the fabrication of an innovative device to directly convert solar energy into electrical power based on optical rectified nano-rectenna.

1) Hetero- and nano-structures based on III-V (GaAs/AlGaAs) and II-VI (CdTe) semiconductors, such as nano-islands and dense vertical arrays of nanowires grown by self-assembly processes and selective area epitaxy have been the subject of intense recent examination due to their

Design of novel plasmonic metamaterials based on different effects of plasmon coupling:
