제목 Black Phosphorus Nonvolatile Transistor Memory
초록 In this communication, we fabricated the nano floating gate transistor memories using mechanically−exfoliated few−layer BP channels and gold nanoparticle charge trapping layers. The cross−linked poly−4−vinylphenol (cPVP) and SiO2 were utilized as the tunneling and blocking gate dielectrics, respectively. The hole carriers in the BP channel could be trapped effectively in the AuNPs upon applying negative gate voltages, while the trapped charges in the AuNPs could be detrapped under positive gate voltages. By carefully controlling the number of the trapped/detrapped charges, five−level data storage having sufficient reading margins in the signal could be achieved over three orders of span in the current level. The resulting BP−NFGTMs exhibited excellent memory performances, including a large memory window (58.2 V), stable retention (104 s), and cyclic endurance (200 cycles).
