Application of lock-in amplifier SE1022 in the measurement of self-rolled three-dimensional photothermoelectric detector
This research used three-dimensional self-curling nanotechnology and combined it with thermoelectric functional materials to successfully design and manufacture a new self-curling three-dimensional photothermoelectric detector. The three-dimensional tubular structure significantly enhances light absorption and thermal localization effects, and improves light-heat-electricity conversion efficiency through locally concentrated photothermal energy. This self-curling photothermoelectric detector not only has high sensitivity and wide spectral response range, but also has unique functions such as self-driving, omnidirectional detection and polarization imaging, which indicates its huge application potential in on-chip integrated optoelectronic systems.
