Abstract:
Photoconductivity and its control in the Terahertz (THz) regime holds the potential to enhance communication systems worldwide. In order to investigate the photoconduction behavior of epitaxial NdNiO3 thin films we employed the technique of Optical Pump THz probe (OPTP) spectroscopy. While the compressively strained film on LaAlO3(100) demonstrates uniform THz photoconductivity without any discernible anisotropy, the tensile strained film on NdGaO3(001) displays anisotropic behavior in THz photoconductivity, accompanied by a reversal in the sign of photoconductivity. Upon modulation of oxygen vacancy levels, the compressively strained film maintains its isotropic photoconductivity, whereas the tensile strained film exhibits modulation in this anisotropic response. This regulated reversal in photoconductivity sign has the potential to stimulate the advancement of a three-state high speed and reliable communication system
