Narrow band gap III-V based nanowires are subject to intense research, notably thanks to the exceptional mobility of the carriers. Moreover, due to the strong spin-orbit coupling combined with the ability to host superconductivity, they provide a platform for the realization of Majorana fermions. Here, the authors performed very high field magnetotransport measurements (50T) on InAs nanowires in both longitudinal and perpendicular configuration, giving access, in the quasiballistic regime, to the energy spectrum. The experimental results are supported by band-structure calculations in the tight-binding approximation. Finally, under very strong magnetic field, the authors observed the formation of Landau states and cyclotron orbits in both configurations.
