| Popis: | Both thermal conductivity λ and specific heat cp of amorphous polystyrene were measured in the temperature range 1.7 K K at three different pressure values up to p=0.4 GPa . The thermal conductivity data show that the influence of pressure is most pronounced at the plateau of λ at 2 K K . Fit calculations were carried out to receive values for P γ 2 and W. As pressure is applied the specific heat is clearly reduced below T=20 K . |
