摘要

Multifunctional sensors that can simultaneously detect light and thermal stimuli play an essential role in the research of portable devices and complex arrays of electronics. Lots of effort has been made to realize the simultaneous detection of light and temperature in a standalone device. However, since there is a strong interference of electric signals, accurate simultaneous sensing remains a challenge. Here, a self-powered dual-parameter sensor based on thermo-phototronic effect in Nb-doped SrTiO3 (NSTO) single crystal to achieve decoupled light and temperature sensing is developed. High light- and temperature-sensing sensitivities of 0.201 mu A mW cm(-2) and 16.77 mu A K-1 are realized, respectively. The excellent simultaneous sensing capability may be attributed to effective light-to-electrical and thermal-to-electrical energy conversion in the NSTO crystal. The excellent simultaneous sensing performance of the dual-parameter sensors, together with their ease of fabrication, pushes forward the development of highly sensitive multifunctional sensors.
