Query: Field emission in ultrathin PdSe2 back-gated transistors   We study the electrical transport in back-gate field-effect transistors with
ultrathin palladium diselenide (PdSe2) channel. The devices are normally-on and
exhibit dominant n-type conduction at low pressure. The electron conduction,
combined with the sharp edge and the workfunction decreasing with the number of
layers, opens the way to applications of PdSe2 nanosheets in vacuum
electronics. In this work, we demonstrate field emission from few-layer PdSe2
nanosheets with current up to the uA and turn-on field below 100 V/um, thus
extending the plethora of applications of this recently isolated pentagonal
layered material.
