Area of Science:

  • Physics
  • Materials Science
  • Chemistry

Background:

  • Terahertz (THz) wave interactions with samples are often weak, limiting trace sample detection.
  • Metamaterials offer unique electromagnetic properties for enhancing signal interactions.

Purpose of the Study:

  • To design a graphene-metamaterial absorber heterostructure for sensitive trace sample detection in the terahertz band.
  • To improve the sensitivity of metamaterial absorbers for detecting low concentrations of analytes.

Main Methods:

  • Fabrication of a metamaterial absorber using a gold-high resistance silicon-aluminum three-layer structure.
  • Transferring monolayer graphene onto the metamaterial absorber to create a heterostructure.
  • Simulating and measuring the transmission spectrum using terahertz time-domain spectroscopy.

Main Results:

  • The graphene-metamaterial absorber heterostructure exhibited an obvious resonance frequency shift.
  • Detection of josamycin antibiotic solution at a concentration of 0.02 mg/L (0.2 ng mass).
  • Sensitivity was increased by an order of magnitude compared to the metamaterial absorber alone.
  • A relative change in heterostructure reflectivity of up to 40% was achieved.

Conclusions:

  • The developed graphene-metamaterial absorber heterostructure significantly enhances sensitivity for trace sample detection.
  • This provides a new, accurate, and rapid detection method in the terahertz band.
  • The heterostructure shows promise for sensitive detection of antibiotics and other trace substances.
