[18p-E311-12] Impact of scaling down the VO2 Mott transistor below material correlation length
Keywords:metal-insulator transition, inhomogeneity, steep slope
An ideal Mott transistor would show a sharp ON/OFF switching due to the metal-insulator transition in the channel material. In practice, however, the switching becomes gradual due to the inhomogeneous transition which is inherent to the metal-insulator transition. In this study, the VO2-channel Mott transistor is scaled down to the inhomogeneous length scale of the metal-insulator transition, and the ultra-sharp switching is obtained by electrostatic gating.
