研究目的
To describe a novel type of long-wavelength radiation detector that measures illumination intensity at room temperature through mechanical transduction, combining low measurement noise, transparency, and flexibility.
研究成果
The study presents a novel, nanoelectromechanical bolometer using 2D materials as absorber and transducer, yielding outstanding thermal sensitivities at room temperature. The device demonstrates superior performance with a thermal responsivity up to -8.581 × 105 V W-1 and a TCR exceeding 133% K-1, opening new routes for producing infrared detectors for wearable applications.
研究不足
The spatial resolution is limited by errors in alignment between the bolometer-edge and the illumination direction and by collimation. The resolution can be optimized by depositing thinner 2D films and further decreasing the thermal conductivity of the substrate.
