Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Heat transport mechanisms present in 2-adamantanone and 1-cyanoadamantane crystals were investigated
in a broad temperature range. To characterize scattering processes, thermal conductivity and heat capacity measurements
were carried out. A particular care was paid to the cooling rate of specimen which influenced the thermal
history of the samples. The experimental results led to a conclusion that under slow cooling the thermal conductivity
reaches the highest values and resembles the behavior of ordered molecular crystals. As for fast
cooling, the “quenching” resulted in changes in both the structure and the temperature dependence of the thermal
conductivity, the latter resembling that of amorphous solids. In heat capacity measurements the thermal history
made on samples did not reflect the preliminary findings known from thermal conductivity results, which could
imply that the observed mechanisms are more complex. |
