Leuven Nanoscience and Nanotechnology Center

From Discovery to Technology

The Leuven Nanocenter brings the research and development activities of the K.U. Leuven in the areas of Nanosciences and Nanotechnology together. The center is formed by groups from different departments and faculties and disposes of the broadest range of materials and tools for Nanosciences and Nanotechnology available in Flanders. Our mission is to strengthen the interdisciplinary research and development activities by implementing around specific themes the complete innovation chain starting from fundamental knowledge and scientific discoveries towards the implementation of practical solutions and complete systems.

• Low-Temperature, Highly Efficient Growth of Carbon Nanotubes on Functional Materials by an Oxidative Dehydrogenation Reaction
  Posted by Jin Won Seo
  In many applications like photovoltaics, fuel cells, batteries, or interconnects in integrated circuits carbon nanotubes (CNTs) have the role of charge transport electrodes. The building of such devices requires an in situ growth of CNTs at temperatures where the structure or chemical composition of the functional materials is unaltered. We report that in a chemical vapor deposition process involv

• Structural and electrical properties of fully strained (In,Ga)As field effect transistors with in situ deposited gate stacks
  Posted by Jean-Pierre Locquet
  Metal-oxide-semiconductor field-effect transistors 􏰃MOSFETs􏰂 were fabricated with amorphous Al2O3 and HfO2 / SiOx – Si gate stacks, grown by molecular beam deposition. As and In oxides were observed at the Al2O3/In0.17Ga0.83As interface, whereas no oxides were detected on the Si-passivated In0.17Ga0.83As surface after HfO2 deposition. Traces of As were found in both gate stacks.

• Transition from turbulent to nearly laminar vortex flow in superconductors with periodic pinning
  Posted by Victor Moshchalkov
  We revisit the vortex dynamics in Al thin films containing an artificial periodic array of antidots by means of electrical transport measurements. We clearly identify a turbulent to laminarlike vortex flow transition which manifests itself as a negative differential resistivity.
  
  
  

• Nominal and effective dosimetry of silica nanoparticles in cytotoxicity assays
  Posted by Jin Won Seo
  Because of their small size and large specific surface area (SA), insoluble nanoparticles are almost not affected by the gravitational force and are generally formulated in stable suspensions or sols. This raises, however, a potential difficulty in in vitro assay systems in which cells adhering to the bottom of a culture vessel may not be exposed to the majority of nanoparticles in suspension. J.

• Classification and control of the origin of photoluminescence from Si nanocrystals
  Posted by Andre Stesmans
  Silicon dominates the electronics industry, but its poor optical properties mean that III-V compound semiconductors are preferred for photonics applications. Photoluminescence at visible wavelengths was observed from porous Si at room temperature in 1990, but the origin of these photons (do they arise from highly localized defect states or quantum confinement effects?) has been the subject of inte

• Primary Si-29 hyperfine structure of E
  Posted by Andre Stesmans
  Point defects in fumed similar to 7- nm- sized fumed silica nanoparticles have been studied by X-, K-, and Q- band electron spin resonance ( ESR ) following 10- eV irradiation. The E' defects are monitored as a function of post manufacture heat treatment with the sample brought into contact with " bulk" Si/ SiO2 entities at elevated temperatures in vacuum ( T-an= 1005 - 1205 degrees C ), i. e., th
