Tuning of the Thermoelectric Figure of Merit of CH3NH3MI3 (M=Pb,Sn) Photovoltaic Perovskites

László Forró, Davor Pavuna, Endre Horvath, Bálint Náfrádi, Andrea Pisoni, Massimo Spina, Xavier François Mettan, Péter Krisztián Matus

The hybrid halide perovskites, the very performant compounds in photovoltaic applications, possess large Seebeck coefficient and low thermal conductivity, making them potentially interesting high figure of merit (ZT) materials. For this purpose, one needs ...

Crystal Structure, Transport, and Magnetic Properties of an Ir6+ Compound Ba8Al2IrO14

László Forró, Henrik Moodysson Rønnow, Arnaud Magrez, Alla Arakcheeva, Krunoslav Prsa, Andrea Pisoni, Ana Akrap, Jacim Jacimovic, Sergiy Katrych, Lin Yang, Bastien Dalla Piazza

The novel iridate Ba8Al2IrO14 was prepared as single crystals by self-flux method, thereby providing a rare example of an all-Ir(VI) compound that can be synthesized under ambient pressure conditions. The preparation of all-Ir6+ iridate without using tradi ...

Graphene : from Growth to Devices

Laurent Syavoch Bernard

We report a full study of graphene synthesis by CVD on Cu surface. Two CVD methods have been developed. The first is a static one, which yields monolayer of graphene at low pressure of methane in 3 minutes at 1000 C. The second one is an equimolar method w ...

Magnetic Nernst effect

Jean-Philippe Ansermet, Sylvain Bréchet

The thermodynamics of irreversible processes in continuous media predicts the existence of a magnetic Nernst effect that results from a magnetic analog to the Seebeck effect in a ferromagnet and magnetophoresis occurring in a paramagnetic electrode in cont ...

Variational principle for magnetisation dynamics in a temperature gradient

Jean-Philippe Ansermet, Sylvain Bréchet

By applying a variational principle on a magnetic system within the framework of extended irreversible thermodynamics, we find that the presence of a temperature gradient in a ferromagnet leads to a generalisation of the Landau-Lifshitz equation with an ad ...

Effect of C-face 4H-SiC(0001) deposition on thermopower of single and multilayer graphene in AA, AB and ABC stacking

Giovanni Pizzi

The Seebeck coefficient in multilayer graphene is investigated within the density-functional theory, using the semiclassical Boltzmann equations and interpolating the bands in a maximally-localized Wannier functions basis set. We compare various graphene s ...
