WebFeb 9, 2024 · Carriers quickly condense into excitons. In QRs, electrons within the shell contribute to a significant photoconductivity, which is reduced after electron localization within the core, followed by exciton condensation. Despite the modest localization, core electrons show a negligible contribution to the QR photoconductivity. Web1. Introduction to Terahertz Photoconductive Antennas. Terahertz (THz) is the name given to the region of the electromagnetic spectrum lying between the microwave band (< 100 GHz) and the far infrared band (> 10 THz). 1 This region is often referred to as “the last frontier” for electromagnetic waves, since historically there has been comparatively little work …

WebPhotoconductivity is the increase in electrical conductivity of a material that takes place when the material is illuminated with infrared, visible, or ultraviolet light. The absorption of light is a quantum process in which electrons are excited to higher energy levels. Ordinarily, the excited electrons are more mobile than unexcited electrons. http://outreach.phys.uh.edu/index_files/PPT/Florida_state/conductivity.pdf
