As silicon is the basis of conventional electronics, so strontium titanate (SrTiO3) is the foundation of the emerging field of oxide electronics. SrTiO3 is the preferred template for the creation ofâ€¦ (More)

We study the efficiency at maximum power of two coupled heat engines, using thermoelectric generators (TEGs) as engines. Assuming that the heat and electric charge fluxes in the TEGs are stronglyâ€¦ (More)

We show how the formalism used for thermoelectric transport may be adapted to Smoluchowski's seminal thought experiment, also known as Feynman's ratchet and pawl system. Our analysis rests on theâ€¦ (More)

Atomistic simulations of electron and phonon transport are performed within the non-equilibrium Green's function formalism to analyze the thermal and electrical properties of graphene nanoribbonsâ€¦ (More)

We present an in-depth analysis of the sometimes understated role of the principle of energy conservation in linear irreversible thermodynamics. Our case study is that of a thermoelectric generatorâ€¦ (More)

The Curzon-Ahlborn efficiency has long served as the definite upper bound for the thermal efficiency at maximum output power, and has thus shaped the development of finite-time thermodynamics. Inâ€¦ (More)
