A donor atom in a semiconductor has a loosely bound electron. The orbit of this electron is considerably affected by the semiconductor material but behaves in many ways like an electron orbiting a hydrogen nucleus. Given that the electron has an effective mass of `0.07 m_(e )`, (where me is mass of the free electron) and the space in which it moves has a permittivity `13 epsilon_(0)`, then the radius of the electron's lowermost energy orbit will be close to (The Bohr radius of the hydrogen atom is `0.53 Å`)
