abstract = {{We report an anisotropic formation of defects in cubic GaN grown on nano-patterned 3C-SiC/Si (001) by molecular
beam epitaxy. Nano-patterning of 3C-SiC/Si (001) is achieved by nanosphere lithography and a reactive
ion etching process. Atomic force microscopy and scanning electron microscopy show that the selectivearea-
grown cubic GaN nucleates in two structurally different domains, which most probably originate from the
substrate. In adjacent domains the formation of defects, especially hexagonal inclusions, is different and leads to
two different surface morphologies. The dominant phase within these domains was measured by electron backscatter
diffraction. Optical properties were investigated by micro-photoluminescence and cathodoluminescence spectroscopy.}},

abstract = {{The structural and vibrational properties of lithium niobate (LN) – lithium tantalate (LT) mixed crystals (LNT, LiNb1-xTaxO3) are investigated over the whole composition range by first-principles simulations. The crystal volume grows roughly linearly from LT to LN, whereby the lattice parameters a and c show minor deviations from the Vegard behavior between the end compounds, LiNbO3 and LiTaO3. Our calculations in the framework of the density functional theory show the TO1, TO2 and TO4-modes to become harder with increasing Nb concentration. TO3 becomes softer with increasing Nb content, instead. The frequency shifts of the zone center A1-TO phonon modes for crystals with different compositions are found to be as large as 30 cm-1. Raman spectroscopy, which is sensitive to the A1 modes, can be therefore employed to determine the crystal composition.}},

abstract = {{Coherent physics and applications of exciton qubits in electric fi eld tunable quantum dot structures are our focus. Excitations with picosecond (ps) laser pulses result in qubit rotations. Using state projection by tunnelling the readout can be performed in quantitative way. As a function of electric fi eld induced detuning Ramsey fringes of a single exciton qubit can be observed and controlled for double pulse excitation. Therefore it is possible to demonstrate voltage controlled qubit manipulations within a wide range of pulse delays. Using fast electric signals, phase-locked to ps-laser pulses, the coherent control of an exciton qubit can be obtained by electric interaction. Such voltage controlled qubit manipulations seem to be essential for new types of optoelectronic quantum gates and novel applications in the fi eld of coherent optoelectronics.}},

atmospheres in an electron cyclotron resonance (ECR) plasma etcher were studied on Novasic
substrates with 10 μm thick 3C-SiC(100) grown on Si(100). To achieve reasonable etching rates, a
special gas inlet system suitable for injecting SF6 into the high density downstream Ar ECR plasma
was designed. The influence of the etching mask material on the sidewall morphology was
investigated. Masking materials with small grain sizes are preferable to achieve a desired shape.
The evolution of the mesa form was investigated in dependence on the gas composition, the applied
bias, the pressure and the composition of the gas atmosphere. The achieved sidewall slope was 84.5
deg. The aspect ratios of the fabricated structures in the developed residue free ECR plasma etching
process were between 5 and 10. Mesa structures aligned to [100] and [110] directions were
fabricated.}},

Random walks are a powerful mathematical method that can be used to simulate certain processes in biology, chemistry, or even the stock market. They present a statistical method for mapping the possible routes that processes can take. Quantum walks are expected to be able to probe multiple paths simultaneously. Quantum walks have been demonstrated for one-dimensional, or straight-line, walks. Now,
Schreiber

(p.

, published online 8 March) demonstrate an optical system that can simulate quantum walks over a two-dimensional system, thereby providing the capability of describing much more complex processes.
