Abstract

Low-temperature-grown (LTG) semiconductors have been a mandatory for the photo-conductive detection of pulse and continuous-wave THz radiations due to their sub-picosecond carrier lifetime by intentionally incorporated trapping centers. In this work, we present a new approach to achieve the required ultrafast response by manipulating local carrier dynamics in a nanostructure.
