Example of FTIR

 

Broad range Terahertz spectroscopy
 
•Video rate capable and phase sensitive ASOPS system
•FTIR with cryogenic detectors

 

 

 

     Measurements in (a) frequency-domain and (b) in time-doman.
(c) Conductivity calculated from combination of FTIR, ASOPS, and VNA data.

     A self-assembly method is developed of embedding controllable semimetallic nanostructures in a semiconducting matrix in a ErSb/GaSb material system grown by molecular beam epitaxy. The plasmonic properties of the material are characterized and quantified by three polarization-resolved spectroscopy techniques, spanning more than 3 orders of magnitude in frequency from 100 GHz up to 300 THz.
