The Kinetic Energy Dependent Effective Debye Temperature For Cos2 (100), Ning Wu, David Wisbey, Takashi Komesu, Z. X. Yu, M. Manno, L. Wang, C. Leighton, Peter A. Dowben

Peter Dowben Publications

The effective Debye temperatures of the highly spin-polarized material CoS2 were measured using temperature dependent low energy electron diffraction and shown to be dependent upon electron kinetic energy. The normal dynamic motion of the (100) surface results in the effective surface Debye temperature of 326 ± 9 compared to a bulk Debye temperature of 612 ± 24 K. Similar values for the bulk Debye temperature have been obtained through LEED I(V) analysis and core level photoemission with a lower value for the bulk Debye temperature found from heat capacity measurements.
