Low-temperature vibration characteristics in InSe single crystals intercalated by Ni

Анотація:

The theoretical and experimental study of low-temperature heat capacity of InSe intercalated by nickel as a function of temperature has been carried out in range 0.3–30 K. The effect of intercalation by nickel on phonon heat capacity (Cph) of InSe has been investigated. Two peaks observed in relative change of phonon specific heat (∆Cph/Cph) suggested non-Debye excess in heat capacity for all intercalated NixInSe systems.
