Two-electron states of a group-V donor in silicon from atomistic full configuration interactions

Investigation of electron and hydrogenic-donor states confined in a permeable spherical box using B-splines

  Effects of quantum size and potential shape on the spectra of an electron and a hydrogenic-donor at the center of a permeable spherical cavity have been calculated, using linear variational method. B-splines have been used as basis functions. By extensive convergence tests and comparing with other results given in the literature, the validity and efficiency of the method were confirmed.

Fine Splitting of Electron States in Silicon Nanocrystal with a Hydrogen-like Shallow Donor

Electron structure of a silicon quantum dot doped with a shallow hydrogen-like donor has been calculated for the electron states above the optical gap. Within the framework of the envelope-function approach we have calculated the fine splitting of the ground sixfold degenerate electron state as a function of the donor position inside the quantum dot. Also, dependence of the wave functions and e...

Atomistic Structure of Band-Tail States in Amorphous Silicon

The nature of the band-tail states in amorphous semiconductors is of both fundamental and applied interest. Since the seminal work of Anderson [1] it has been known that disorder induces localization of electron states. The detailed understanding of this has been a field of tremendous activity in condensed matter theory. In the parlance of amorphous semiconductors, the nature of the electron lo...
