Indirect exciton-phonon dynamics in MoS2 revealed by ultrafast electron diffraction
Jianbo Hu, Yang Xiang, Beatrice Matilde Ferrari +2
Transition metal dichalcogenides layered nano-crystals are emerging as promising candidates for next-generation optoelectronic and quantum devices. In such systems, the interaction…
Thermodynamic driving force in the formation of hexagonal-diamond Si and Ge nanowires
E. Scalise, A. Sarikov, L. Barbisan +4
The metastable hexagonal-diamond phase of Si and Ge (and of SiGe alloys) displays superior optical properties with respect to the cubic-diamond one. The latter is the most stable a…
Origin and nature of killer defects in 3C-SiC for power electronic applications by a multiscale atomistic approach
Emilio Scalise, Luca Barbisan, Andrey Sarikov +3
3C-SiC epitaxially grown on Si displays a large wealth of extended defects. In particular, single, double and triple stacking faults (SFs) are observed in several experiments to co…
Kinetic Control of Morphology and Composition in Ge/GeSn Core/Shell Nanowires
Simone Assali, Roberto Bergamaschini, Emilio Scalise +8
The growth of Sn-rich group-IV semiconductors at the nanoscale provides new paths for understanding the fundamental properties of metastable GeSn alloys. Here, we demonstrate the e…
Temperature-dependent stability of polytypes and stacking faults in SiC: reconciling theory and experiments
Emilio Scalise, Anna Marzegalli, Francesco Montalenti +1
The relative stability of SiC polytypes, changing with temperature, has been considered a paradox for about thirty years, due to discrepancies between theory and experiments. Based…
Getting through the nature of silicene: sp2-sp3 two-dimensional silicon nanosheet
E. Cinquanta, E. Scalise, D. Chiappe +5
By combining experimental techniques with ab-initio density functional theory calculations, we describe the Si/Ag(111) two-dimensional system in terms of a sp2-sp3 crystalline form…
