摘要：
We proposed a hybrid transfer method for continuous and triangular monolayer MoS2 and experimentally analyzed their excitonic photoluminescence and optoelectrical properties on Au interdigital electrodes. The photoluminescence intensities of both MoS2 on interdigital Au were lower than those of the MoS2 on SiO2/Si, and continuous MoS2 on interdigital Au showed the highest A(-)/A(0) exciton ratio. Furthermore, the formed Au/MoS2/Au devices exhibited light-dependent Schottky-contact characteristics and the I (D)-V (D) hysteresis. The results provide a basis for understanding the photoluminescence and optoelectrical properties of different MoS2-Au contacts for improving the performance of MoS2-based optoelectrical devices.
