Abstract

The invention provides a two-dimensional Te nanosheet flexible transparent near-infrared photoelectric detector and a preparation method thereof. The two-dimensional Te nanosheet flexible transparent near-infrared photoelectric detector comprises a flexible substrate, a transparent electrode and two-dimensional Te nanosheets; the transparent electrode is located on the flexible substrate, and the material of the transparent electrode is MXene-Ti3C2Tx; the two-dimensional Te nanosheets are erected on the positive electrode and the negative electrode of the transparent electrode and are communicated with the positive electrode and the negative electrode of the transparent electrode. The electrode is made of the two-dimensional material and can be in better contact with the two-dimensional active material, so that the device has lower dark current, and the current is more stable along with time change in the whole test process.
