| Popis: | 106 Recently, transition metal dichalcogenides, （TMDc） such as MoS2, WSe2 and other single layer materials of two-dimensional semiconductors have drawn high attentions of the academia due to their great flexibility, high photo-response, high absorption rate and good electronic transmission. This research uses photolithography and lift-off method for fabricating IDT on LiNbO3 substrate. The aluminum electrode was deposited using RF sputter system. In addition, the mechanical exfoliation was used to prepare two-dimensional hetero-structure atomic layer at surface acoustic wave devices. The circuits are connected with frequency spectrum to measure its frequency response. Eventually, the oscillator platform of two-dimensional hetero-structure atomic layer examination is designed according to reflection model. The circuit is initial simulated by high frequency analyze software. The multi-photon excitation microscopy is then analyzing the ''excitation'' of two-dimensional hetero-structure atomic layer excited by acoustic wave. |
