Unusual Aharonov-Bohm oscillations in the energy and magnetic dipole moment of a semiconductor conical nanotube under external fields

Semiconductor nanostructures are an active subject of research by its quantum properties and its potential applications. Nanostructures include nanoparticles, nanowires, quantum wells, and other nanometric structures. We modeled by finite element method the spectrum of an electron confined in a truncated cone-shaped CdSe nanotube. Simulations include the study of the electron energy behavior and the magnetic dipole moment in an electric and magnetic field, including the simultaneous application of both fields. The results of simulations reveal an atypical behavior in the Aharonov-Bohm oscillations in the energy and the magnetic dipole moment when the nanotube's conicity degree increases. We also found the possibility of restructuring the nanostructure's magnetic properties through the application of electric fields. In this way, this work shows that semiconductor conical nanotubes can be ideal candidates for the design of materials with novel magnetoelectric properties.
