  2. 1. Quantum Correlations and Temperature Fluctuations in Nanoscale Systems

    Author : Fredrik Brange; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum transport; electronic entanglement; nanoscale thermodynamics; quantum calorimetry; Fysicumarkivet A:2019:Brange;

    Abstract : This thesis addresses two different topics related to the physics of nanoscale systems. The first topic concerns quantum correlations and entanglement between electrons in solid-state systems, with a focus on how to generate electronic orbital entanglement on a sub-decoherence time scale and how to achieve experimentally more feasible entanglement detection schemes.

  4. 2. Nanoscale structure forming processes : Metal thin films grown far-from-equilibrium

    Author : Viktor Elofsson; Kostas Sarakinos; Robert D. Boyd; Diederik Depla; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Thin film growth from the vapor phase has for a long time intrigued researchers endeavouring to unravel and understand atomistic surface processes that govern film formation. Their motivation has not been purely scientific, but also driven by numerous applications where this understanding is paramount to knowledge-based design of novel film materials with tailored properties.

  5. 3. Fluctuations and nonequilibrium thermodynamics in electronic nanosystems

    Author : Ludovico Tesser; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Charge; heat and spin transport; Hot-carrier solar cell; Nonequilibrium thermodynamics; Fluctuations and noise; Shot noise; Mesoscopic thermoelectricity;

    Abstract : In the last decades thermodynamics has seen a resurgence because of the interesting phenomena that happen in small-scale systems. Indeed, in nanoscale devices, quantum effects and fluctuations cannot generally be neglected and influence both the transport and their thermodynamic performance. READ MORE

  6. 4. There Is an Alloy at the End of the Rainbow: Structure and Optical Properties From Bulk to Nano

    Author : Magnus Rahm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thermodynamics; optical properties; dielectric functions; hydrides; alloy cluster expansions; alloys; nanoalloys;

    Abstract : Mixing different chemical species and decreasing dimensions to the nanoscale are two powerful approaches for improving materials. In both cases new properties emerge, and structure, composition, and chemical ordering can be tuned to tailor materials for specific purposes. READ MORE

  7. 5. Heat control in mesoscopic conductors - exploiting quantum effects and size confinement

    Author : Fatemeh Hajiloo; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heat currents; thermoelectric devices; nonequilibrium thermodynamics.; fluctuations; phase-dependent heat transport;

    Abstract : This thesis deals with a theoretical analysis of heat currents, their exploitation and their control in nanoscale devices. The motivation for this study is twofold. (i) The development of nanoscale devices sets up the basis of many applications ranging from nanoelectronics to quantum technology. READ MORE
