A set of photoconductive antennas based on single-crystal diamonds doped with boron (\u223c1 ppm) is assembled and tested under pumping conditions with ultrashort (<i>\u03c4<\/i><sub>opt<\/sub> \u2248 150 fs) radiation pulses with a wavelength of 800 nm and a pulsed voltage (<i>\u03c4<\/i><sub><i>E<\/i><\/sub> \u2248 10 ns, <i>E<\/i><sub>bias<\/sub> \u2248 10 kV\u00b7cm<sup>\u20131<\/sup>). The performance of the boron-doped emitters is compared with recently implemented nitrogen-doped diamond antennas pumped with 400 nm radiation pulses, since substituted nitrogen requires a much higher quantum energy for single-photon excitation of carriers. The results obtained are another step towards the use of diamond as a material for high-performance photoconductive antennas.<\/div>\n<div><\/div>\n<div class=\"around-button\"><b>Keywords:<\/b> photoconductive antennas, diamond, doping, terahertz sources<\/div>\n<div><\/div>\n<div><b>Received:<\/b> 19.12.2022<br \/>\n<b>Accepted:<\/b> 19.12.2022<\/div>\n","protected":false},"excerpt":{"rendered":"<p>V.
