Abstract: A method of providing an electric device with a vertical component and the device itself are disclosed. The electric device may be a transistor device, such as a FET device, with a vertical channel, such as a gate around transistor, or double-gate transistor First an elongate structure, such as a nanowire is provided to a substrate. Subsequently, a first conductive layer separated from the substrate and from the elongate structure by a dielectric layer is provided. Further, a second conductive layer being separated from the first conductive layer by a separation layer is being provided in contact with at least a top section of the elongate structure.

Abstract: The invention relates to an optical information recording medium and methods and devices to record and read information thereto and thereof. The optical information recording medium comprises luminescent nano-elements. The nano-element species differ in at least one luminescence wavelength. Therefore, a specific luminescence signal is obtained in accordance with the nano-element species irradited by a reading light beam. Methods and devices to record and read information by using such optical information recording media are also described.

Abstract: The compound nanotubes of InP or another II-VI or III-V material show a very large blueshift. Thus, devices with photoluminescent and electroluminescent effects in the visible range of the electromagnetic spectrum are provided by the inclusion of such nanotubes.
