발명의 명칭: Graphene device having physical gap
대표도면:
대표독립항:
1. A graphene device comprising:
a source and a drain, formed on a substrate;
a stack structure having a graphene channel formed on the substrate between the source and the drain, a dielectric layer on the graphene channel, and a gate formed on the dielectric layer; and
a high-K spacer made of a dielectric material on the left and right sides of the stack structure,
in which any one or more of the source and the drain are spaced apart from the graphene channel by a physical gap extending in a planar direction,
wherein the physical gap includes a thickness of the high-K spacer and an empty space spaced apart from the graphene channel,
wherein when a voltage lower than the threshold voltage of the device is applied to the gate, the off-current of the device is reduced due to the physical gap, and when a voltage higher than the threshold voltage is applied to the gate, a fringing field is formed by the high-K spacer, so that the energy band of the substrate region under the high K-spacer is inversed and the effective length of the physical gap is reduced to increase the on-current of the device because of a breakdown occurring in the substrate region corresponding to the physical gap.

발명의 명칭: Black organic light-emitting diode device
대표도면:
대표독립항:
1. A black organic light-emitting diode device, comprising:
a glass substrate;
a first metal layer formed on the glass substrate;
a first electrode formed on the first metal layer; an organic light-emitting layer formed on the first electrode;
a second electrode formed on the organic light-emitting layer so as to face the first electrode;
a first interlayer formed on the second electrode;
a second metal layer formed on the first interlayer; and a second interlayer formed on the second metal layer,
wherein thicknesses of the first interlayer and the second interlayer are adjusted so that external light reflected from the first metal layer and the second electrode destructively interferes with light reflected from the second metal layer.
