Vertically stacked multiple MoS2 channels are required for the performance matching. Resistive switching (RS) of a Ti/MoS2 /p+-Si structure showing high ON/OFF ratio of 106 is demonstrated firstly by highly Si-compatible process. Surface modification is the key to formation of uniform and smooth stacked MoS2 multiple channels and to enhanced resistive switching endurance. This scheme can be applied to CMOS-based bipolar RRAM 1T1R or 2T1R without increasing the cell size. Our work offers a new pathway with high feasibility of integrated 2D materials and Si FETs into CMOS to enabling 3D embedded logics and memories for future computing systems. ? 2020 IEEE. |
