We discuss experimental and theoretical studies of the generation of the third terahertz
(THz) frequency harmonic in thin films of Bi2Se3 and Bi2-xSbxTe3-ySey (BSTS) topological …

Emission of THz radiation from air breakdown at focused ultra-short fs-laser pulses (800
nm/35 fs) was investigated for the 3D spatio-temporal control where two pre-pulses are used …

Abstract Antimony telluride (Sb 2 Te 3) thin films were deposited on to non-and conductive-
glass substrates‒borosilicate (BRS), indium-doped tin oxide (ITO), and fluorine-doped tin …

Terahertz third-harmonic generation in topological insulators based on bismuth and
antimony chalcogenides has been experimentally investigated. It has been found that the …

The design of multiband antennas is useful for providing multiple resonance frequencies
required for multiple application scenarios. However, there is a scarcity of compactsized …

The demand for ultrahigh-speed, lightweight, low-cost, and defect-tolerant electronic devices
drives the industry to switch to terahertz (THz) technologies. The use of two-dimensional …

Topological insulators made of bismuth chalcogenides are promising materials for sources
and converters of terahertz radiation. The operation of a topological insulator nanofilm …

Nonlinear optics, which emerged in the early 60s of the 20th century, immediately after the
invention of powerful lasers, had a significant influence on the formation of modern …

In this work, we present the first experimental observation of the enhanced THz radiation in
plasmonic photoconductive antenna (PCA) based on Bi_2-xSb_xSe_yTe_3-y topological …
