Stability of Mn2Ru Ga-based multilayer stacks

Self-assembly of DNA arrays into multilayer stacks.

We describe the self-assembly of multilayer hexagonal DNA arrays through highly regular interlayer packing. Slow cooling of a mixture of three single-stranded DNA sequences with various Mg2+ concentrations leads to the self-assembly of diverse multilayer architectures. The self-assembled aggregates were deposited onto mica surfaces and examined with atomic force microscopy. The size of the two-...

Variational calculations on multilayer stacks of dipolar Bose-Einstein condensates

We investigate a multilayer stack of dipolar Bose-Einstein condensates in terms of a simple Gaussian variational ansatz and demonstrate that this arrangement is characterized by the existence of several stationary states. Using a Hamiltonian picture we show that in an excited stack there is a coupled motion of the individual condensates by which they exchange energy. We find that for high excit...

Porous silicon multilayer stacks for optical biosensing applications

Porous silicon (PS) multilayer stacks were developed for their use as interference filters in the visible range. The optical behavior of these structures was previously simulated by the use of a computational program, from which the optical constants and thickness of the individual PS layers were determined. The possibility of using these structures as biosensors has been explored, based on the...

Black Multicrystalline Solar Modules Using Novel Multilayer Antireflection Stacks

Today multiand monocrystaline solar cells are typically wet-chemically textured and coated with a thin layer of silicon nitride to reduce losses due to light reflection and for electrical passivation of the silicon surface. In this paper we investigate a layer stack consisting of silicon nitride (SiNx:H) with a high refractive index at the silicon interface, an intermediate SiNx:H layer and on ...
