Characterization of the feature-size dependence in Ar/Cl2 chemically assisted ion beam etching of InP-based photonic crystal devices

The authors address feature-size dependence in Ar/Cl2 chemically assisted ion beam etching (CAIBE) in the context of the fabrication of photonic crystal (PhC) structures. They systematically investigate the influence of various parameters such a ...

About the influence of friction and polydispersity on the jamming behavior of bead assemblies

Thomas Liebling, Lionel Pournin, Marco Ramaioli

We study the jamming of bead assemblies placed in a cylindrical container whose bottom is pierced with a circular hole. Their jamming behavior is quantified here by the mean critical diameter, that is the diameter of the hole for which the jamming probabil ...

Single hole and vortex excitations in the doped Rokhsar-Kivelson quantum dimer model on the triangular lattice

Dmitri Ivanov, Samuel Bieri, Hugo Ribeiro

We consider the doped Rokhsar-Kivelson quantum dimer model on the triangular lattice with one mobile hole (monomer) at the Rokhsar-Kivelson point. The motion of the hole is described by two branches of excitations: the hole may either move with or without ...

Practical aspects of running the WIEN2k code for electron spectroscopy

Cécile Hébert

The Wien2k code is widely used for the calculation of electron energy loss spectra. Low loss spectra can be calculated with the OPTIC package while core loss spectra are calculated with the TELNES program. A new version, TELNES.2, takes into account the ef ...

Memory Effect of Metal-Insulator-Silicon Capacitor with HfO2-Al2O3 Multilayer and Hafnium Nitride Gate

Wei Chen

Metal-insulator-silicon capacitors have been fabricated using novel insulators of SiO2/HfO2-Al2O3-HfO2 (HAH)/Al2O3 and metallic HfN gate, exhibiting a program-erasable characteristic. The memory capacitor presents a large memory window of 2.4 V under +12 V ...

From fundamental strings to small black holes

We give evidence in favour of a string/black hole transition in the case of BPS fundamental string states of the Heterotic string. Our analysis goes beyond the counting of degrees of freedom and considers the evolution of dynamical quantities in the proces ...

Block copolymer micelles as switchable templates for nanofabrication

Jürgen Brugger, Sivashankar Krishnamoorthy, Harry Heinzelmann, Raphaël Pugin

Block copolymer inverse micelles from polystyrene-block-poly-2-vinylpyridine (PS-b-P2VP) deposited as monolayer films onto surfaces show responsive behavior and are reversibly switchable between two states of different topography and surface chemistry. The ...

The rod and hole paradox re-examined

Christian Gruber, Harald Van Lintel

In the rod and hole paradox as described by Rindler (1961 Am. J. Phys. 29 365–6) ('length contraction paradox'), a rigid rod moves at high speed over a table towards a hole of the same size. A bystander expects the rod to fall into the hole, but a co-movin ...

Minigap in a SN junction with paramagnetic impurities

Benoît Crouzy, Dmitri Ivanov

We study the effect of spin-flip scattering on the density of states in a long diffusive S-N junction with transparent interface. We calculate the critical value of the spin-flip scattering rate at which the minigap closes and give the dependence of the mi ...

Investigation of hexagonal and cubic GaN by high-resolution electron energy-loss spectroscopy and density functional theory

Cécile Hébert

High-resolution electron energy-loss spectroscopy in a transmission electron microscope is a very powerful method for the study of electronic structure of materials. The fine structure of Ga L2,3 and N ionization edges in c-GaN and h-GaN was studied using ...
