      abstract     = {Three-dimensional topological insulator (3D TI) nanowires
                      display remarkable magnetotransport properties that can be
                      attributed to their spin-momentum-locked surface states such
                      as quasiballistic transport and Aharonov–Bohm
                      oscillations. Here, we focus on the transport properties of
                      a 3D TI nanowire with a gated section that forms an
                      electronic Fabry–Pérot (FP) interferometer that can be
                      tuned to act as a surface-state filter or energy barrier. By
                      tuning the carrier density and length of the gated section
                      of the wire, the interference pattern can be controlled and
                      the nanowire can become fully transparent for certain
                      topological surface-state input modes while completely
                      filtering out others. We also consider the interplay of FP
                      interference with an external magnetic field, with which
                      Klein tunneling can be induced, and transverse asymmetry of
                      the gated section, e.g. due to a top-gated structure, which
                      displays an interesting analogy with Rashba nanowires. Due
                      to its rich conductance phenomenology, we propose a 3D TI
                      nanowire with gated section as an ideal setup for a detailed
                      transport-based characterization of 3D TI nanowire surface
                      states near the Dirac point, which could be useful towards
                      realizing 3D TI nanowire-based topological superconductivity
                      and Majorana bound states.},
