Reconfigurable behavior of CdTe quantum dots at terahertz frequencies employing UV excitation
2017
We report the synthesis and characterization of cadmium-telluride (CdTe) quantum dots (QDs) and their performance at Terahertz frequencies employing THz time-domain spectroscopy (THZ-TDS). The data was analyzed using a combination of Fast Fourier Transform (FFT) and effective medium theory to obtain the optical characteristics of the aforementioned CdTe QDs. Additionally, we performed similar measurements while exposing the QDs to a UV excitation with a wavelength of 302 nm and observed a noticeable variation in both the real and imaginary components in the index of refraction that could prove crucial in the demonstration of reconfigurable devices operating in the THz regime.
