Can 2D-Nanocrystals Extend the Lifetime of Floating-Gate Transistor Based Nonvolatile Memory?

Andras Kis, Simone Bertolazzi, Wei Cao

Conventional floating-gate (FG) transistors (made with Si/poly-Si) that form the building blocks of the widely employed nonvolatile flash memory technology face severe scaling challenges beyond the 12-nm node. In this paper, for the first time, a comprehen ...

Nonvolatile Memory Cells Based on MoS2/graphene heterostructures

Andras Kis, Simone Bertolazzi, Daria Krasnozhon

Memory cells are an important building block of digital electronics. We combine here the unique electronic properties of semiconducting monolayer MoS2 with the high conductivity of graphene to build a 2D heterostructure capable of information storage. MoS2 ...

Stretching and Breaking of Ultrathin MoS2

Andras Kis, Jacopo Brivio, Simone Bertolazzi

We report on measurements of the stiffness and breaking strength of monolayer MoS2, a new semiconducting analogue of graphene. Single and bilayer MoS2 is exfoliated from bulk and transferred to a substrate containing an array of microfabricated circular ho ...
