▎ 摘　　要

NOVELTY - The method involves preparing an electrode to be tested of a graphene probe. A graphene probe control electrode is prepared. An in-situ electrochemical Raman device is constructed. An original position Raman spectrum of the electrode of the graphene probe is tested. A relation curve is obtained between a peak wave number and an external electric potential when the electrode is controlled by the graphene probes. The relation curve and the reference curve are compared to obtain an original position Fermi level of an electrode. The electrode is provided with a first electrode and a second electrode. USE - The method is useful for detecting opaque photoelectric pole Fermi level. ADVANTAGE - The method can directly measure the photoelectric pole Fermi level which is not easy to measure, which is good for further optimizing the material of the light electrode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a non-transparent photoelectric pole Fermi level detecting system. DESCRIPTION OF DRAWING(S) - The drawing shows a detection schematic diagram of method for detecting opaque photoelectric pole Fermi level (Drawing includes non-English language text).
