Enhanced Terahertz Radiation Generation of Photoconductive Antennas Based on Manganese Ferrite Nanoparticles
This paper presents a significant effect of manganese ferrite nanoparticles (MnFe2O4 NPs) on the increase of the surface photoconductivity of semiconductors. Herein, the optical characterization of photo-excited carriers of silicon coated with MnFe2O4 NPs was studied by using THz time-domain spectroscopy (THz-TDs). We observed that silicon coated with MnFe2O4 NPs provided a significantly enhanc...
متن کاملA Broadband THz-TDS System Based on DSTMS Emitter and LTG InGaAs/InAlAs Photoconductive Antenna Detector
We demonstrate a 4-f terahertz time-domain spectroscopy (THz-TDS) system using an organic crystal DSTMS as the THz emitter and a low temperature grown (LTG) InGaAs/InAlAs photoconductive antenna as the receiver. The system covers a frequency range from 0.2 up to 8 THz. The influences of the pump laser power, the probe laser power and the azimuthal angle of the DSTMS crystal on the time-domain T...

15 صفحه اولBroadband THz Generation from Photoconductive Antenna
Since the observation of radiation in the Terahertz (THz) frequency range from photoconductive antennas exited by femtosecond (fs) laser pulses, considerable efforts have been made to understand the mechanism responsible for THz generation, and to develop applications in THz Time-Domain Spectroscopy (THz-TDS). In this paper, the calculation of THz radiation from biased photoconductive antenna i...
