 This research used a laser terahertz emission microscopy, LTM, to explore the nature of the carrier dynamics in a multi-layered crystalline by 2T3, tellurium, teheutectic composite. It found that the t-hertz emission electric fields at the by 2T3, teh interface were polarized perpendicular to the interface, which indicated the direction of the electric field between the two components. Additionally, it discovered a strong t-hertz emission with an electric field polarized parallel to the interface in the tehe region. This phenomenon could be explained by considering the effective mass of electrons and holes. The results of this study suggest that the eutectic heterostructure may be useful for developing novel thermoelectric and photovoltaic devices.
