摘要:
The present invention relates to an electronic device comprising a substrate and at least two electrodes spaced by a nanogap, wherein the at least two electrodes are bridged by at least one nanoparticle and wherein the at least one nanoparticle has an overlap area with the at least two electrodes higher than 2% of the area of the at least one nanoparticle. The present invention also relates to a method of manufacturing of said electronic device and to the use of said electronic device in photodetector, transistor, phototransistor, optical modulator, electrical diode, photovoltaic cell or electroluminescent component.
摘要:
The invention relates to a device that emits light in response to an electrical or luminous excitation, such as light-emitting diodes, displays, and e-readers. Such devices are for example found in displays, televisions, mobile phones, tablet computers, or even desktop computers. The present invention makes it possible to produce a light-emitting device that exhibits a very narrow emission spectrum and, simultaneously, allows perfect control of the wavelength, the directivity and/or the polarization of the emitted light, and thus allows the brightness and the range of displays composed from such devices to be increased. More particularly, the invention relates to a device that emits light in response to the activation of excitation means, this device comprising at least one flattened anisotropic colloidal semiconductor nanocrystal the smallest dimension of which, namely its thickness, is smaller than the two others by a factor of at least 1.5, the intensity and polarization of said emitted light varying as a function of the angle between the emission direction of the light and the normal to the largest surface of the flattened nanocrystal. Various embodiments of these devices are also presented.
摘要:
The invention relates to a method of increasing the thickness of at least one face of an inorganic colloidal sheet. The invention further relates to the homostructured or heterostructured materials resulting from such a method and the applications of said materials. Sheet designates a structure having at least one nanoscale dimension, the thickness, and lateral dimensions larger than the thickness, typically more than 5 times the thickness. Homostructured designates a material having a homogeneous composition in thickness, and heterostructured designates a material having a heterogeneous composition in thickness. More particularly, the invention relates to a method used to deposit at least one monolayer of atoms on at least one inorganic colloidal sheet, said monolayer consisting of atoms of the type of those contained or not contained in said sheet. The use of the material obtained is also presented.
