Title: Crossover between Electron-Phonon and Boundary-Resistance Limits to Thermal Relaxation in Copper Films

Abstract

We observe a crossover from electron-phonon (e-ph) coupling limited energy relaxation to that governed by thermal boundary resistance (phonon-phonon coupling, ph-ph) in copper films at subkelvin temperatures. Our measurement yields a quantitative picture of heat currents, in terms of temperature dependences and magnitudes, in both e-ph and pp limited regimes, respectively. We show that by adding a third layer in between the copper film and the substrate, the thermal boundary resistance is increased fourfold, consistent with an assumed series connection of thermal resistances.

Evidence of enhanced electron-phonon coupling in ultrathin epitaxial copper films

Journal Article Timalsina, Yukta P., E-mail: timaly@rpi.edu ; Shen, Xiaohan ; Boruchowitz, Grant ; ... - Applied Physics Letters

Electron phonon (el-ph) coupling is a fundamental quantity that controls the electron transport through a conductor. We experimentally determined the el-ph coupling strength of epitaxial copper (Cu) films ranging from 5 to 1000 nm thick using both ultra-fast, optical pump-probe reflectivity and temperature-dependent resistivity measurements. An enhancement of the el-ph coupling strength was observed when the thickness of the films was reduced to below 50 nm. We suggest that this unexpected enhancement of the el-ph coupling strength is partially responsible for the observed increase of resistivity in the films below 50 nm thick.

Influence of structural relaxation upon the low temperature properties of metallic glasses. [CuZr; Metglas 2826; PdSiCu; Zr/sub 3/Rh]

Technical Report Cotts, E J

Below 1K, the thermal conductivity of metallic glasses (Fe/sub 40/Ni/sub 40/P/sub 14/B/sub 6/, Pd/sub 77/ /sub 5/Si/sub 16/ /sub 5/Cu/sub 6/ and Zr/sub 3/Rh) is similar to that of the large class of amorphous materials. The influence of the electron-phonon interaction upon the phonon thermal conductivity kappa/sub ph/ (T < 1K) in PdSiCu agree well with theoretical prediction. We have found no effect upon kappa/sub ph/ due to boundary scattering in our samples. We have deduced the glassy thermal conductivity kappa/sub glass/ for Zr/sub 3/Rh and PdSiCu from our measurements, where 1/kappa/sub glass/ is the thermal resistivity intrinsic to themore »« less
Many-polaron theory for superconductivity and charge-density waves in a strongly coupled electron-phonon system with quasi-two-dimensionality: An interpolation between the adiabatic limit and the inverse-adiabatic limit

Journal Article Nasu, K - Phys. Rev. B: Condens. Matter; (United States)

The phase diagram of a two-dimensional N-site N-electron system (N>>1) with site-diagonal electron-phonon (e-ph) coupling is studied in the context of polaron theory, so as to clarify the competition between the superconducting (SC) state and the charge-density wave (CDW) state. The Fermi surface of noninteracting electrons is assumed to be a complete circle with no nesting-type instability in the case of weak e-ph coupling, so as to focus on such a strong coupling that even the standard ''strong-coupling theory'' for superconductivity breaks down. Phonon clouds moving with electrons as well as a frozen phonon are taken into account by amore »« less

Mechanisms of nonequilibrium electron-phonon coupling and thermal conductance at interfaces

Journal Article Giri, Ashutosh ; Gaskins, John T. ; Donovan, Brian F. ; ... - Journal of Applied Physics

We study the electron and phonon thermal coupling mechanisms at interfaces between gold films with and without Ti adhesion layers on various substrates via pump-probe time-domain thermoreflectance. The coupling between the electronic and the vibrational states is increased by more than a factor of five with the inclusion of an ∼3 nm Ti adhesion layer between the Au film and the non-metal substrate. Furthermore, we show an increase in the rate of relaxation of the electron system with increasing electron and lattice temperatures induced by the laser power and attribute this to enhanced electron-electron scattering, a transport channel that becomes moremore »« less

Effective thermal boundary resistance from thermal decoupling of magnons and phonons in SrRuO3 thin films

Journal Article Langner, M C ; Kantner, C L.S. ; Chu, Y H ; ... - Physical Review Letters

We use the time-resolved magneto-optical Kerr effect (TRMOKE) to measure the local temperature and heat flow dynamics in ferromagnetic SrRuO3 thin films. After heating by a pump pulse, the film temperature decays exponentially, indicating that the heat flow out of the film is limited by the film/substrate interface. We show that this behavior is consistent with an effective boundary resistance resulting from disequilibrium between the spin and phonon temperatures in the film.
