Thermoelectricity and Heat Transport in Graphene and Other 2D Nanomaterials

Thermoelectricity and Heat Transport in Graphene and Other 2D Nanomaterials describes thermoelectric phenomena and thermal transport in graphene and other 2-dimentional nanomaterials and devices. Graphene, which is an example of an atomic monolayered material, has become the most important growth area in materials science research, stimulating an interest in other atomic monolayeric materials. The book analyses flow management, measurement of the local temperature at the nanoscale level and thermoelectric transducers, with reference to both graphene and other 2D nanomaterials. The book covers in detail the mechanisms of thermoelectricity, thermal transport, interface phenomena, quantum dots, non-equilibrium states, scattering and dissipation, as well as coherent transport in low-dimensional junctions in graphene and its allotropes, transition metal dichalcogenides and boron nitride. This book aims to show readers how to improve thermoelectric transducer efficiency in graphene and other nanomaterials. The book describes basic ingredients of such activity, allowing readers to gain a greater understanding of fundamental issues related to the heat transport and the thermoelectric phenomena of nanomaterials. It contains a thorough analysis and comparison between theory and experiments, complemented with a variety of practical examples. Shows readers how to improve the efficiency of heat transfer in graphene and other nanomaterials with analysis of different methodologiesIncludes fundamental information on the thermoelectric properties of graphene and other atomic monolayers, providing a valuable reference source for materials scientists and engineersCovers the important models of thermoelectric phenomena and thermal transport in the 2D nanomaterials and nanodevices, allowing readers to gain a greater understanding of the factors behind the efficiency of heat transport in a variety of nanomaterials INDICE: I.
