چکیده
|
We explore the optical and electrical characteristics of monolayer graphene by using pulsed optoelectronic terahertz time-domain spectroscopy in the frequency range of 325-500 ghz based on fast direct measurements of phase and amplitude. we also show that these parameters can,however,be measured with higher resolution using a free space continuous wave measurement technique associated with a vector network analyzer that offers a good dynamic range. all the scattering parameters (both magnitude and phase) are measured simultaneously. the nicholson-ross-weir method is implemented to extract the monolayer graphene parameters at the aforementioned frequency range. © 2014 ehsan dadrasnia,et al.
