    • Analysis of the temperature dependence of the thermal conductivity of insulating single crystal oxides 

      Langenberg Pérez, Eric; Ferreiro Vila, Elías; Leborán Alvarez, Víctor; Fumega, Adolfo; Pardo, Victor; Rivadulla Fernández, José Francisco (AIP Publishing LLC, 2016-10)
      The temperature dependence of the thermal conductivity of 27 different single crystal oxides is reported from ≈20 K to 350 K. These crystals have been selected among the most common substrates for growing epitaxial thin-film ...
    • Ferroelectric Domain Walls in PbTiO3 Are Effective Regulators of Heat Flow at Room Temperature 

      Langenberg Pérez, Eric; Saha, Dipanjan; Holtz, Megan E.; Wang, Jian-Jun; Bugallo Ferrón, David; Ferreiro Vila, Elías; Paik, Hanjong; Hanke, Isabelle; Ganschow, Steffen; Muller, David A.; Chen, Long-Qing; Catalan, Gustau; Domingo, Neus; Malen, Jonathan; Schlom, Darrell G.; Rivadulla Fernández, José Francisco (American Chemical Society, 2019)
      Achieving efficient spatial modulation of phonon transmission is an essential step on the path to phononic circuits using “phonon currents”. With their intrinsic and reconfigurable interfaces, domain walls (DWs), ferroelectrics ...
    • PEG 400-Based Phase Change Materials Nano-Enhanced with Functionalized Graphene Nanoplatelets 

      Marcos, Marco A.; Cabaleiro, David; García Guimarey, María Jesús; Pérez Comuñas, María José; Fedele, Laura; Fernández Pérez, Josefa; Lugo, Luis (MDPI, 2018)
      This study presents new Nano-enhanced Phase Change Materials, NePCMs, formulated as dispersions of functionalized graphene nanoplatelets in a poly(ethylene glycol) with a mass-average molecular mass of 400 g·mol−1 for ...
    • Strong enhancement of phonon scattering through nanoscale grains in lead sulfide thermoelectrics 

      Wu, Haijun; Carrete Montaña, Jesús; Zhang, Zhiyun; Qu, Yongquan; Shen, Xuetao; Wang, Zhao; Zhao, Li-Dong; He, Jiaqing (Nature Publishing Group, 2014)
      We present nanocrystalline PbS, which was prepared using a solvothermal method followed by spark plasma sintering, as a promising thermoelectric material. The effects of grains with different length scales on phonon ...
    • Study and Control of Thermal Transport in Complex Fluids 

      López Bueno, Carlos (2021)
      In this thesis, we propose the study of heat transport in liquids as a novel approach to the study of the dynamic structure of liquids. We focus our attention on the thermal conductivity, which is highly sensitive to ...
