This invention is a photon-interactive gaussian surface lens method means that converts incident photons from a single or a plurality of wide band gap semiconductor class light emitting diode dies, into a secondary emission of photons emanating from a composite photon transparent colloidal stationary suspension of quantum dots, high efficiency phosphors, a combination of quantum dots and high efficiency phosphors and nano-particles of metal, silicon or similar semiconductors from the iiib and ivb group of the periodic table and any nano-material and/or micro/nano spheres that responds to rayleigh scattering and/or mie scattering; and a plurality of quantum dots in communication with said nano-particles in said suspension. The patent teaches that utilizing this method means results in improved narrow pass-band of red, green, and blue photon efficiency over phosphor based conversion.

Composition for increasing the lipophobicity of a watch-making component
The present invention describes the highly advantageous properties of a mixture of thiol-perfluoropolyether (pfpe) molecules with perfluorinated bisphosphonic (pf-bp) compounds. This mixture makes it possible in effect to obtain a lipophobic behaviour (also referred to as “epilame” effect) with common watch-making lubricants on all the materials tested, including metals, inter alia gold and alloys thereof, ceramics and semiconductors, and gives the surface treated a good resistance to ageing and to cleaning products..

Method and apparatus for high resolution photon detection based on extraordinary optoconductance (eoc) effects
The inventors disclose a new high performance optical sensor, preferably of nanoscale dimensions, that functions at room temperature based on an extraordinary optoconductance (eoc) phenomenon, and preferably an inverse eoc (i-eoc) phenomenon, in a metal-semiconductor hybrid (msh) structure having a semiconductor/metal interface. Such a design shows efficient photon sensing not exhibited by bare semiconductors.

Semiconductor heterostructure and transistor of hemt type, in particular for low-frequency low-noise cryogenic applications.
A semiconductor heterostructure having: a substrate (ss); a buffer layer (h); a spacer layer (d, e, f); a barrier layer (b, c); and which may also include a cover layer (a) is provided. The barrier layer is doped (ds); and the barrier and spacer layers are made of one or more semiconductors having wider bandgaps than the one or more materials forming the buffer layer, the heterostructure being characterized in that: the barrier layer comprises a first barrier sublayer (c) in contact with the spacer layer, and a second barrier sublayer (b), distant from the spacer layer; and in that the second barrier sublayer has a wider bandgap than the first barrier sublayer.
