Effect of anodic oxidation on the characteristics of lattice-matched AlInN/GaN heterostructures

Nicolas Grandjean, Jean-François Carlin, Eric Feltin

The effect of anodic oxidation on the electronic characteristics of lattice-matched AlInN/GaN heterostructures was investigated using field-effect transistor (FET) structures with the gate areas in direct contact with the electrolytes. The gate surface of ...

Recent ARPES experiments on quasi-1D bulk materials and artificial structures

Marco Grioni, Emmanouil Frantzeskakis

The spectroscopy of quasi-one-dimensional (1D) systems has been a subject of strong interest since the first experimental observations of unusual line shapes in the early 1990s. Angle-resolved photoemission (ARPES) measurements performed with increasing ac ...

Contact and edge effects in graphene devices

Klaus Kern, Marko Burghard, Kannan Balasubramanian, Ralf Thomas Weitz, Eduardo Jian Hua Lee

Electrical transport studies on graphene have been focused mainly on the linear dispersion region around the Fermi level(1,2) and, in particular, on the effects associated with the quasiparticles in graphene behaving as relativistic particles known as Dira ...

Electronic origin of the isostructural decomposition in cubic M1-xAlxN (M=Ti, Cr, Sc, Hf): A first-principles study

Alireza Karimi

We have used first-principles calculations to investigate the mixing enthalpies, lattice parameters and electronic density of states of the ternary nitride systems Ti1-xAlxN, Cr1-xAlxN, Sc1-xAlxN and Hf1-xAlxN in the cubic B1 structure where the transition ...

Competing orders in strongly correlated systems studied by transport measurements

Ana Akrap

Competing orders in strongly correlated systems lead to rich phase diagrams comprising many electronic phases, such as superconductivity, charge/spin density wave, charge order, or bad metallicity. These phases are generically sensitive to a variety of par ...

Kinks in the angle resolved photoemission and inelastic x-ray spectra of high temperature superconductors

Jeff Graf

Though the high superconducting transition temperature (Tc) is the most interesting technological aspect of high temperature superconductors, the complex way in which the spin, lattice and electronic degrees of freedom interplay, makes them of the highest ...

wannier90: A tool for obtaining maximally-localised Wannier functions

Nicola Marzari

We present wannier90, a program for calculating maximally-localised Wannier functions (MLWF) from a set of Bloch energy bands that may or may not be attached to or mixed with other bands. The formalism works by minimising the total spread of the MLWF in re ...

The growth by laser ablation and electronic properties of thin cuprate films

Claudia Cancellieri

In my thesis work I have concentrated on the growth and the in-depth analysis of high temperature superconducting thin films with the central aim to elucidate their electronic properties, predominantly by in-situ angle resolved photoemission spectroscopy ( ...
