IntroductionThere are increasing concerns regarding long-term psychotropic polypharmacy prescribed for foster care youth 3.5 to 5 times more often than in at-home youth (Kreider et al., 2014). Polypharmacy risks include weight gain, glucose intoleran

IntroductionIt is well known that youth in foster care are at high risk for psychiatric disorders, recently reported in up to 89%, with over 55% exhibiting ADHD in one sample (Linares et al., 2013). Psychotropic medication use was reported in 59% of

The critical current in a superconductor/two-dimensional electron gas junction/superconductor junction is controlled by an injection current. In case of a carrier injection from one contact to the semiconductor through the two-dimensional electron ga

Ni ++ ion irradiations of a Nb-stabilized steel of type 1.4981 were performed at 400, 500, and 600°. Dislocation loop evolution with increasing dose and radiation-induced segregation at grain boundaries were observed by transmission electron microsc

Fe and Si were codeposited on Si(111) with an understoichiometric atomic ratio of 1:3 at substrate temperatures between 580 and 720 °C in order to investigate the nucleation and growth of silicide precipitates under growth conditions similar to mole

Using spatially resolved energy-loss spectroscopy, electron diffraction, and He+-ion channeling we have observed the evolution of α-Fe disilicide layers from primary crystallographically badly defined FeSi2 precipitates with increasing Fe dose in as

We fabricated Si/FeSi 2 /Si(111) heterostructures by a new method, called molecular beam allotaxy (MBA). Codeposition of silicon and iron at temperatures around 650°C leads to the formation of FeSi 2 precipitates in the crystalline silicon matrix. T

Using energy‐loss spectroscopy, energy dispersive x‐ray analysis, electron diffraction, and He+‐ion channeling the reaction of Fe during implantation into Si(111) has been investigated at various target temperatures and implantation doses. In s

Using analytical electron microscopy and Auger depth profiling the reactionof 10 nm thick poly- and epi-Fe films on Si(111) Si(100), and poly-Si surfaces has been investigated. Already at room-temperature deposition β-FeSi2 is formed locally but sti

The supercurrent in a Nb–In0.53Ga0.47As/In0.77Ga0.23As/InP weak link structure is controlled by means of a current injected into the two-dimensional electron gas. For small injection currents the critical current to control current ratio is as larg
