Knowledge Society and the Knowledge Gap
Knowledge has been widely recognised by economists as the most important factor of production in a “new economy”. The production and utilisation of knowledge is therefore essential for development. Some countries, Malaysia among others, have embarked on an ambitious plan to use knowledge as a base for economic development, by-passing earlier stages of industrialisation. Some commentators have, ...
متن کاملStrongly enhanced molecular fluorescence inside a nanoscale waveguide gap.
We experimentally demonstrate dramatically enhanced light-matter interaction for molecules placed inside the nanometer scale gap of a plasmonic waveguide. We observe spontaneous emission rate enhancements of up to about 60 times due to strong optical localization in two dimensions. This rate enhancement is a nonresonant nature of the plasmonic waveguide under study overcoming the fundamental ba...
متن کاملHubbard gap modulation in vanadium dioxide nanoscale tunnel junctions.
We locally investigate the electronic transport through individual tunnel junctions containing a 10 nm thin film of vanadium dioxide (VO2) across its thermally induced phase transition. The insulator-to-metal phase transition in the VO2 film collapses the Hubbard gap (experimentally determined to be 0.4 ± 0.07 V), leading to several orders of magnitude change in tunnel conductance. We quantitat...
متن کاملApplication of narrow band-gap materials in nanoscale spin filters
We develop a simple analytical model to study the influence of different material systems on the operation of a quantum-point-contact spin filter. Such a device has been predicted to allow for local control of the spin polarization in a semiconductor, and for direct electrical detection of the induced spin polarization. Narrow band-gap semiconductors, such as InAs and InSb, are predicted to exh...
متن کاملClosing the AI Knowledge Gap
AI researchers employ not only the scientific method, but also methodology from mathematics and engineering. However, the use of the scientific method – specifically hypothesis testing – in AI is typically conducted in service of engineering objectives. Growing interest in topics such as fairness and algorithmic bias show that engineering-focused questions only comprise a subset of the importan...
