Pressure-tuned Transport Properties of Novel Iron-based Superconductors and Topological Insulators

Andrea Pisoni

The majority of interactions in solids strongly depend on the interatomic distances. The application of pressure changes the lattice parameters and modifies the electronic and the phononic energy spectra of a material avoiding some of the undesirable effec ...

From Twinning to Pure Zincblende Catalyst-Free InAs(Sb) Nanowires

Anna Fontcuberta i Morral, Federico Matteini, Esther Alarcon Llado, Martin George Friedl, Heidi Andrea Potts, Francesca Amaduzzi

III-V nanowires are candidate building blocks for next generation electronic and optoelectronic platforms. Low bandgap semiconductors such as In As and InSb are interesting because of their high electron mobility. Fine control of the structure, morphology, ...

Thermal induced structural properties of silver(I) sulphate (Ag2SO4)

Philip Pattison

The crystal structures of silver(I) sulphate, Ag2SO4, have been investigated as a function of temperature. A main feature is the phase transition from the low-temperature ordered phase, F ddd, to the high-temperature disordered phase, P63/mmc. In particula ...

The low-temperature crystal structure of the multiferroic melilite Ca2CoSi2O7

Bálint Náfrádi

In the antiferromagnetic ground state, below T-N similar or equal to 5.7 K, Ca2CoSi2O7 exhibits strong magnetoelectric coupling. For a symmetry-consistent theoretical description of this multiferroic phase, precise knowledge of its crystal structure is a p ...

Magnetotransport studies of superconducting Pr4Fe2As2Te1-xO4

László Forró, Richard Gaal, Bálint Náfrádi, Janusz Andrzej Karpinski, Andrea Pisoni, Sergiy Katrych, Péter Szirmai

We report a study of the electrical transport properties of single crystals of Pr(4)Fe(2)As(2)Te(1-)xO(4), a recently discovered iron-based superconductor. Resistivity, Hall effect, and magnetoresistance are measured in a broad temperature range revealing ...

Investigation of interactions in two-dimensional electron gases with angular resolved photoemission spectroscopy

Carola Strasser

In this thesis, angular resolved photoemission spectroscopy (ARPES) is used to study the electronic structure of different two-dimensional electron systems (2DES). This technique is very surface sensitive and the most direct method to probe the surface ban ...

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

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

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 ...

Vortex lattice structure in BaFe2(As0.67P0.33)(2) via small-angle neutron scattering

Jonathan White

We have observed a magnetic vortex lattice (VL) in BaFe2(As0.67P0.33)(2) (BFAP) single crystals by small-angle neutron scattering. With the field along the c axis, a nearly isotropic hexagonal VL was formed in the field range from 1 to 16 T, and no symmetr ...
