Summary on Grant Application Form |
|
Car-Parrinello simulation in combination with other techniques, including the GW approximation for quasiparticle energies, will be used to elucidate the structure, dynamics and electronic properties of the liquid chalcogens, primarily Se and Te. The simulations will be based on the DFT-pseudopotential method. The quantities of interest will be the time-averaged structure, the electronic density of states (DOS), the electrical conductivity, the viscosity, the self-diffusion coefficient, and the bond lifetime, and we aim to elucidate the relations between them. Quasiparticle energies will be important, because we know from our own previous work that the Kohn-Sham energies will give an adequate treatment of DOS and conductivity. The work will also employ spin-DFT to probe the effect of spin fluctuations on the properties of the liquid. These fluctuations are expected to play an important role, because it is widely believed that the free chain ends are associated with dangling bonds and unpaired spins.
