title = "Ferroelectrically gated atomically thin transition-metal dichalcogenides as nonvolatile memory",
abstract = "Ferroelectrically driven nonvolatile memory is demonstrated by interfacing 2D semiconductors and ferroelectric thin films, exhibiting superior memory performance comparable to existing thin-film ferroelectric field-effect transistors. An optical memory effect is also observed with large modulation of photoluminescence tuned by the ferroelectric gating, potentially finding applications in optoelectronics and valleytronics.",

note = "Funding Information: This work was supported by a NSF CAREER Award under the Grant No. DMR-1055938. The 2D materials preparation and processing were partially supported by a NSF grant under the Grant No. DMR-1306601. Y.L. is supported by the NSF-TANMS Center and J.D.C. is supported by a SRC FAME program. C.K. and J.W. conceived the research and designed the experiments. C.K. carried out all the optical and electrical measurements and data analysis. Y.L., J.D.C. and R.R. grew and characterized the PZT films. C.K., Y.C., J.S., D.F., S.L., and H.S.C. prepared the 2D flakes and fabricated the devices collaboratively. A.S. and S.T. synthesized the WSe2 single crystals. The project was supervised by J.W. All the authors discussed results and contributed to writing the manuscript. The authors declare no competing financial interests. The authors thank Dr. Eunpa Kim, Prof. Kai Liu, and Dr. Deyang Chen for useful discussions and appreciate Taegyun Park's assistance in 2D material preparation.
