A field effect transistor using several atomic layers of molybdenum disulfide (MoS₂) as the channel material was used in the experiment. Irradiating the surface with monochromatic visible light, it is possible to measure the photocurrent spectrum. Experiments were carried out with the aim of performing molecular sensing by analyzing the spectrum when molecules are adsorbed on the MoS₂ surface. In this experiment, we investigated the dependence on the amount of copper naphthalocyanine molecules (CuNPc) adsorbed.
