Area of Science:

  • Optoelectronics
  • Materials Science
  • Nanotechnology

Background:

  • Graphene exhibits excellent carrier mobility and broad spectral response, making it suitable for photodetection.
  • High dark current in graphene photodetectors limits room-temperature sensitivity, especially for low-energy photons.
  • Existing graphene photodetectors face challenges in achieving high sensitivity at room temperature.

Purpose of the Study:

  • To develop a novel graphene-based photodetector for sensitive detection of low-energy photons at room temperature.
  • To overcome the limitation of high dark current in graphene photodetectors.
  • To design and investigate asymmetric lattice antennas integrated with graphene monolayers.

Main Methods:

  • Fabrication of asymmetric lattice antennas.
  • Integration of high-quality graphene monolayers with the antennas.
  • Characterization of the photodetector's performance at terahertz frequencies.
  • Measurement of responsivity, response time, and noise equivalent power.

Main Results:

  • The graphene terahertz detector-based microstructure antenna demonstrated a responsivity of 29 V·W-1 at 0.12 THz.
  • A fast response time of 7 μs was achieved.
  • The noise equivalent power was measured to be less than 8.5 pW/Hz1/2.
  • The asymmetric antenna configuration enabled sensitive detection of low-energy photons.

Conclusions:

  • The proposed asymmetric lattice antenna design effectively enhances the sensitivity of graphene photodetectors for low-energy photons.
  • This approach offers a viable strategy for developing high-performance, room-temperature terahertz photodetectors.
  • The findings pave the way for advancements in graphene array-based terahertz imaging and sensing applications.
