Abstract
Official abstract text for this publication.
Provided are a photosensor and a method of operating the same. The photosensor includes a lower electrode, a semiconductor layer, a 2-dimensional material layer, and an upper electrode. Photocurrent generated due to externally radiated light may be operated in a multiple detection mode including a lateral detection mode and a vertical detection mode. The upper electrode may include a plurality of electrode elements, which may be formed of the same conductive material or different conductive materials.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operating a photosensor for light detection, the photosensor comprising a lower electrode, a semiconductor layer formed on the lower electrode, a 2-dimensional material layer formed on the semiconductor layer, and an upper electrode that contacts the 2-dimensional material layer, the 2-dimensional material layer having one continuous layer of a 2-dimensional material, and the upper electrode including at least two electrode elements, each of the electrode elements being in contact with the one continuous layer of the 2-dimensional material, the electrode elements being spaced apart from one another in a lateral direction on the one continuous layer, the method comprising: detecting light radiated to the 2-dimensional material layer, in a multiple detection mode wherein the multiple detection mode includes a lateral detection mode and a vertical detection mode, wherein the upper electrode includes a plurality of electrode elements, wherein the lateral detection mode includes measuring photocurrent generated due to light radiated to the 2-dimensional material layer, using the electrode elements of the upper electrode, and wherein the vertical detection mode includes measuring photocurrent generated due to light radiated to the 2-dimensional material layer by using the upper electrode and the lower electrode. 2. The method of claim 1 , wherein the lateral detection mode and the vertical detection mode are alternately executed. 3. The method of claim 1 , wherein the upper electrode includes a first upper electrode and a second upper electrode, each of which is in contact with the 2-dimensional material layer, and wherein the photocurrent generated due to the light radiated to the 2-dimensional material layer is measured using the first upper electrode and the second upper electrode.
