Mattis, Daniel C. | Eigenstates of excitons near a surface | The exact eigenstates and energies of an electron and a hole of equal effective masses, with an attractive δ-function interaction and hard-wall repulsion at the surfaces of a solid, are classified and obtained explicitly for a solid of arbitrary thickness. Both bound and scattering states of the e... | Eigenstates; Frenkel excitons | 1978-10 |

Vardeny, Zeev Valentine | Specific heats and lattice dynamics of cuprous halides | The specific heats Cp(T) of CuCl, CuBr, and Cul were measured by the adiabatic calorimetric technique. The corresponding Debye temperature for each crystal is given and a comparison between the results is drawn. The room-temperature phonon dispersion relations for these cystals are fitted by a nine... | Cuprous halides; CuBr; CuCl; CuI | 1978-10 |
