Nanowires in the CdHgTe Material System

HgTe nanowires have been grown by molecular beam epitaxy (MBE). They are nucleated at Au particles on Si or GaAs substrates and subsequently self-organize and grow laterally on the surface into 20–50 nm wide, ...

Intraspecific competition in Fucus serratus and F. evanescens (Phaeophyceae: Fucales) germlings: effects of settlement density, nutrient concentration, and temperature

Survival and growth of early post-settlement stages are critical for the development of seaweed populations. Fucoid germlings commonly settle in dense monospecific aggregates, where intraspecific competition a...

Minimally cooled heterojunction laser heterodyne detectors in metalorganic vapor phase epitaxially grown Hg_1-xCd_xTe

By taking advantage of Auger suppression techniques, the leakage currents of room temperature infrared detectors operating in the LWIR band can be greatly reduced. At present, these detectors suffer from large...

Characterization of molecular beam epitaxially grown HgCdTe epilayers by mid-infrared interband magneto-absorption

Interband magneto-absorption is used to characterize molecular beam epitaxially (MBE) grown HgCdTe epilayers. Both the bandgap and the Moss-Burstein shift in n-doped layers are determined from the experiments....

Changes in Na⁺, K⁺-adenosinetriphosphatase, citrate synthase and K⁺ in sheep skeletal muscle during immobilization and remobilization

The K⁺ balance and muscle activity seem to interact in a complex way with regard to regulating the muscle density of Na⁺-K⁺ pumps. The effect of immobilization was examined in ten sheep that had low muscle K⁺ con...

Muscle function after femoral shortening osteotomies at the subtrochanteric and mid-diaphyseal level

Relative femoral shortening length at the subtrochanteric (ST) and mid-diaphyseal (MD) level was compared with isokinetic muscle strength more than 2 years postoperatively. For the ST level no upper limit for ...
