Diffuse reflection of phonons and the anomalous Kapitza resistance
High-resolution time-of-flight phonon-reflection spectra in sapphire crystals are analyzed with the aid of detailed numerical calculations. It is argued that spectra from vacuum interfaces may be understood if about half the incident phonons are assumed to be reflected specularly, the remainder diffusely. A simple model of the effect on spectra of diffuse scattering is presented and compared to...
متن کاملObservation of anomalous phonon softening in bilayer graphene.
The interaction of electron-hole pairs with lattice vibrations exhibits a wealth of intriguing physical phenomena such as the renowned Kohn anomaly. Here we report the observation in bilayer graphene of an unusual phonon softening that provides the first experimental proof for another type of phonon anomaly. Similar to the Kohn anomaly, which is a logarithmic singularity in the phonon group vel...
متن کاملAppraisal of the Cmn/helium Kapitza Resistance
It is argued that the thermal resistance between cerium magnesium nitrate (CMN) and pure He,He containing He* impurity or dilute He in He"* can be understood in terms of the phonon bottlenecked spin-lattice resistance within the CMN and a size dependent thermal boundary resistivity. The fact that emerges is that the phonon bottleneck within the CMN is strongly dependent upon whether the CMN is ...
متن کاملObservation of Anomalous Resistance Behavior in Bilayer Graphene
Our measurement results have shown that bilayer graphene exhibits an unexpected sharp transition of the resistance value in the temperature region 200~250 K. We argue that this behavior originates from the interlayer ripple scattering effect between the top and bottom ripple graphene layer. The inter-scattering can mimic the Coulomb scattering but is strongly dependent on temperature. The obser...
