Stark Effect for Donors in Rolled-Up Quantum Well

We calculate energies of shallow donors confined in a rolled-up quantum well the presence electric field by solving numerically Schrödinger equation natural curvilinear coordinates. It is found that curves density states (DOSs) are very sensitive to variation donor position, geometry spiral and applied value. Novel results for dependencies donor’s dipole moment its polarizability on strength orientation, different positions presented. Additionally, we anisotropic Stark effect first order provides this structure dependency external spike-like shape, giving rise sharp moment.
