Thermoelectric materials are widely used in science and technology because of their huge application prospects in many aspects such as clean energy, photoelectron detection, etc. The latest theoretical progress and the discovery of several new materials provide new opportunities for applications. A class of new materials are based on strongly correlated electronic systems, and the classic example is transitional metal oxides, which have not previously been valued in terms of thermoelectric materials. We will discuss a few recent advances that focus on the growth of the inclinometer In this case, the generation of thermoelectric voltage is based on the Seebeck effect of anisotropy.When the light radiation irradiates the surface of the film, the temperature difference between the upper and lower surfaces of the film causes a lateral potential difference, which can be used for light, Thermal Radiation Detection. We demonstrate that these detectors are very energy-efficient due to their unique advantages, broad spectral response, fast time response, and the absence of bias or bias currents. We also discuss several typical materials Performance
