Mattis, Daniel C. | Eigenfunction localization in dilute lattices of various dimensionalities | As a fraction of bonds p is removed from a lattice, we find a threshold PQ above which all eigenstates are nonpropagating (Anderson localized). This occurs well before the classical percolation threshold. For example, in two dimensions where the classical threshold is pc = 1/2 , we find PQ = 0. | Eigenstates; Dilute lattices | 1981-05 |

Vardeny, Zeev Valentine | Hot-carrier thermalization in amorphous silicon | Thermalization of photoinduced carriers in a-Si and α-Si:H was studied with use of sub-picosecond-pump and probe techniques with parallel and perpendicular polarizations. The underlying process was identified as hot-carrier absorption whose cross section increases with the carrier excess energy.
