Article Synopsis
- Terahertz (THz) radiation is crucial for various applications including imaging, sensing, and communication, with future advancements reliant on efficient and simple THz emitters.
- Researchers have demonstrated that using layered transition metal oxides, intense THz radiation can be generated through the transverse thermoelectric effect when exposed to femtosecond laser pulses.
- Experiments with thin films of materials like PdCoO and LaSrCuO highlight the promise of this method for developing versatile and easily integrable THz sources.
High-Temperature Thermoelectricity in LaNiO-LaCuO Heterostructures.
ACS Appl Mater Interfaces
July 2018
Transition metal oxides exhibit a high potential for application in the field of electronic devices, energy storage, and energy conversion. The ability of building these types of materials by atomic layer-by-layer techniques provides a possibility to design novel systems with favored functionalities. In this study, by means of the atomic layer-by-layer oxide molecular beam epitaxy technique, we designed oxide heterostructures consisting of tetragonal KNiF-type insulating LaCuO (LCO) and perovskite-type conductive metallic LaNiO (LNO) layers with different thicknesses to assess the heterostructure-thermoelectric property-relationship at high temperatures.
