Embodiment Construction

[0043] figure 1 The figure shows an example of thermal emission in a graphene field effect transistor and is based on the publication entitled "Thermal emission from large area chemical vapor deposited graphene devices" by I.J. Luxmoore et al. in Applied Physics Letters 103, 131906 (2013). image 3 (a), the contents of which are incorporated herein by reference.

[0044]The graphene field effect transistor includes a graphene monolayer 102 having dimensions of approximately 3.5 mm by 3.5 mm. The left edge of the graphene layer 102 is connected to the drain electrode 104 and the right edge of the graphene layer 102 is connected to the source electrode 106 . Although in figure 1 is not shown, but the device also includes a gate electrode.

[0045] exist figure 1 The heat emission in the device is indicated by cross-shading in , with thinner shading indicating higher heat emission. figure 1 The thermal emission of corresponds to the case where there is zero gate bias and a d...

Abstract

The present invention relates to a transparent heating device comprising: a graphene film fixed to a transparent substrate; a first electrode (205) connected to a first edge of the graphene film; and a second electrode (205) connected to the graphene film. A second electrode (206) at the edge, wherein there is a resistance gradient across the graphene film from the first electrode (205) to the second electrode (206).

Description

technical field [0001] The present disclosure relates to a transparent heating device, and in particular, to a graphene heating device including a graphene film and a method of forming the graphene heating device. Background technique [0002] For certain applications, such as for windshields or rear view mirrors for motor vehicles, it would be desirable to provide a transparent heating device in the form of a transparent element capable of conducting electrical current across its surface. Thus, by applying a voltage to the electrodes at the edges of the transparent element, the transparent element can be heated. In the case of windshields or mirrors, such heating devices can be used to remove and / or prevent frost formation. [0003] Indium tin oxide (ITO) is a material that provides a transparent conductive layer when applied in thin layers. However, ITO has many disadvantages. In particular, it is a relatively brittle material, making it unsuitable for surfaces that may...
