Electrical Characterization of hexagonal SiGe
Isabelle Bollier, Federico Balduini, Marilyne Sousa +4
We report electrical measurements on hexagonal silicon-germanium (hex-SiGe), a group IV alloy with direct bandgap. Electrical contacts are formed by metal alloying and doping is ac…
Engineering Magnetotransport Through Hierarchical Symmetry in Weyl Semimetal Superlattices
Nathan C. Drucker, Federico Balduini, Jules Schadt +7
Superlattice engineering is a powerful way to tune the transport properties of a material. In this work we show that magnetotransport can be modified by superlattices in 3D materia…
Orientation Dependent Resistivity Scaling in Mesoscopic NbP Crystals
Gianluca Mariani, Federico Balduini, Nathan Drucker +6
The scaling of Si transistor technology has resulted in a remarkable improvement in the performance of integrated circuits over the last decades. However, scaled transistors also r…
Intrinsic negative magnetoresistance from the chiral anomaly of multifold fermions
F. Balduini, A. Molinari, L. Rocchino +7
The chiral anomaly, a hallmark of chiral spin-1/2 Weyl fermions, is an imbalance between left- and right-moving particles that underpins both high and low energy phenomena, includi…
Probing the shape of the Weyl Fermi surface of NbP using transverse electron focusing
F. Balduini, L. Rocchino, A. Molinari +7
The topology of the Fermi surface significantly influences the transport properties of a material. Firstly measured through quantum oscillation experiments, the Fermi surfaces of c…
