Vacuum ultraviolet excitation luminescence spectroscopy of few-layered MoS2

Andras Kis, Daria Krasnozhon, Wei Cao

We report on vacuum ultraviolet (VUV) excited photoluminescence (PL) spectra emitted from a chemical vapor deposited MoS2 few-layered film. The excitation spectrum was recorded by monitoring intensities of PL spectra at similar to 1.9 eV. A strong wide exc ...

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 ...
