On the way to integrate lattice mismatched semiconductors on Si(001), the Ge/ Si heterosystem was used as a case study for the concept of compliant substrate effects that offer the vision to be able to integrate defect-free alternative semiconductor structures on Si. Ge nanoclusters were selectively grown by chemical vapour deposition on Si nano-islands on(More)
Filament-type HfO2-based RRAM has been considered as one of the most promising candidates for future non-volatile memories. Further improvement of the stability, particularly at the "OFF" state, of such devices is mainly hindered by resistance variation induced by the uncontrolled oxygen vacancies distribution and filament growth in HfO2 films. We report(More)
Image processing-based deflagration detection is currently a novel application with a considerable development potential. Moreover, this technology could replace the commonly used infrared photodiode-based detection sensors and can help to avoid tunnel disasters or accidents in chemical plants more reliably. Today's deflagration detection systems only(More)
The practical difficulties to use graphene in microelectronics and optoelectronics is that the available methods to grow graphene are not easily integrated in the mainstream technologies. A growth method that could overcome at least some of these problems is chemical vapour deposition (CVD) of graphene directly on semiconducting (Si or Ge) substrates. Here(More)
The integration of dislocation-free Ge nano-islands was realized via selective molecular beam epitaxy on Si nano-tip patterned substrates. The Si-tip wafers feature a rectangular array of nanometer sized Si tips with (001) facet exposed among a SiO2 matrix. These wafers were fabricated by complementary metal-oxide-semiconductor (CMOS) compatible(More)
Federal agencies must balance privacy protection concerns with the competing priorities of accessibility and usability mandated by open data initiatives. Free text data often provide detail and qualitative value not offered by coded data. However, free text narratives are more likely to contain personally identifiable or sensitive information.

In this work, SrO buffer layers were employed as an interface engineering approach to realize single crystalline mixed ternary rare earth bixbyite oxide (RE<sub>2</sub>O<sub>3</sub>) films on Si (001) substrate. Single crystalline mixed Pr<sub>x</sub>Y<sub>2-x</sub>O<sub>3</sub> (x=0-2) has been successfully grown on Si (111) (Ref. 7). However, the(More)
