Terahertz Generation in Novel 2‐Amino‐5‐Nitropyridinium L (+) Tartrate Single Crystal

Abstract The Terahertz generation is reported from novel single crystals of 2‐amino‐5‐nitropyridinium L(+) tartrate (ANPT), grown by slow evaporation solution growth technique (SEST), using formic acid as the solvent. The preliminary analysis is conducted for the crystal to understand their structural, chemical, thermal, electrical, and optical behavior. Terahertz time domain spectroscopy (THz‐TDS) is used to extract complex refractive index, dielectric constant, and conductivity of the crystal in Terahertz (THz) frequency. The Terahertz emission studies of the grown crystal is conducted and reported for the first time. ANPT crystal is found to generate THz radiation by optical rectification, with emission amplitude comparable to that of commercially used ZnTe crystals. Thus, these crystals could be a prominent candidate in designing Terahertz devices for future applications.
