Summary from Kohesio (English machine translation by the source): The fast-evolving THz spectroscopy and imaging technology has a high demand for powerful, compact and low-cost THz-emitting sources. Currently available subTHz sources are extremely expensive and relatively large, and the emission of quantum cascading lasers operating at room temperature, limited to 4 THz, is not sufficiently permeable. Intensive search is being made for new physical phenomena and device designs to increase the radiant power of THz. This research project proposes a new non-coherent THz source capable of generating THz radiation with sufficient power, permeability and resolution. A completely new operating principle is being developed with an optical/electrical stacked THz lamp based on quantum jumps of chargers in parabolic quantum pits with an attached transverse electric field and stimulating jumps on the attached longitudinal electric field. Photon emissions during charger jumps in parabolic quantum pits are the main radiation mechanism of THz. The theoretical phase of the project includes modelling the THz lamp by theoretically calculating the technological parameters and electrical and radiant characteristics. The second stage involves the production of a prototype device using molecular fibre epitaxy and processing of semiconductor derivatives. In the third stage, the electrical and radiological properties of the THz lamp are experimentally examined. The results of the research will be published in 5 scientific works and presented at 2 international scientific conferences. The project will acquire significant theoretical, technological and experimental knowledge and skills in research and production of THz sources. This will make an important contribution to the future development of THz spectroscopy and winding systems, increasing their competitiveness in terms of application.
