  • Publication number: 20200286604
    Abstract: A method is disclosed for generating a database to be used to set illumination of an adjustable light source. The method comprising: for a plurality of different users: identifying an individual user; setting a specific light profile of the adjustable light source, the specific light profile comprising information pertaining to a spectral content and/or intensity of light by which the individual user is exposed to; while exposing the individual user for the specific light profile, sensing data pertaining to a health condition and/or a behavior of the individual user; determining a data set linking the specific light profile, genomic data pertaining to the individual user, and the data pertaining to the health condition and/or the behavior of the individual user sensed while exposing the individual user to the specific light profile; and storing the linked data set in a database. A light control system is further provided.

  • Patent number: 8669125
    Abstract: A light emitting diode (LED) structure includes a plurality of devices arranged side by side on a support layer. Each device includes a first conductivity type semiconductor nanowire core and an enclosing second conductivity type semiconductor shell for forming a pn or pin junction that in operation provides an active region for light generation. A first electrode layer extends over the plurality of devices and is in electrical contact with at least a top portion of the devices to connect to the shell. The first electrode layer is at least partly air-bridged between the devices.

  • Publication number: 20120211727
    Abstract: The present invention relates to providing layers of different thickness on vertical and horizontal surfaces (15, 20) of a vertical semiconductor device (1). In particular the invention relates to gate electrodes and the formation of precision layers (28) in semiconductor structures comprising a substrate (10) and an elongated structure (5) essentially standing up from the substrate. According to the method of the invention the vertical geometry of the device (1) is utilized in combination with either anisotropic desposition or anisotropic removal of deposited material to form vertical or horizontal layers of very high precision.

  • Patent number: 8063450
    Abstract: The present invention relates to vertical nanowire transistors with a wrap-gated geometry. The threshold voltage of the vertical nanowire transistors is controlled by the diameter of the nanowire, the doping of the nanowire, the introduction of segments of heterostructures in the nanowire, the doping in shell-structures surrounding the nanowire, tailoring the work function of the gate stack, by strain engineering, by control of the dielectrica or the choice of nanowire material. Transistors with varying threshold voltages are provided on the same substrate, which enables the design of advanced circuits utilizing the shifts in the threshold voltages, similar to the directly coupled field logic.
