The key according to UCSB professor of electrical and computer engineering Kaustav Banerjee who led this research is Mos2's band gap the characteristic of a material that determines its electrical conductivity.
but nonzero band gap and can be switched between conductive and insulated states controllably. The larger the band gap the better its ability to switch states and to insulate leakage current in an insulated state.
Mos2's wide band gap allows current to travel but also prevents leakage and results in more sensitive and accurate readings.
While graphene has attracted wide interest as a biosensor due to its two-dimensional nature that allows excellent electrostatic control of the transistor channel by the gate
and high surface-to-volume ratio the sensitivity of a graphene field-effect transistor (FET) biosensor is restricted fundamentally by the zero band gap of graphene that results in increased leakage current leading to reduced sensitivity explained Banerjee
despite graphene's excellent characteristics its performance is limited by its zero band gap. Electrons travel freely across a graphene FETENCE it cannot be switched offhich in this case results in current leakages and higher potential for inaccuracies.
or by introducing defects in the graphene layerr using bilayer graphene stacked in a certain pattern that allows band gap opening upon application of a vertical electric fieldor better control and detection of current.
They have a relatively large and uniform band gap (1. 2-1. 8 ev depending on the number of layers) that significantly reduces the leakage current
and at the same time possess band gap they are not suitable for low-cost mass production due to their process complexities she said.
great electrostatics due to their ultra-thin body scalability (due to large band gap) as well as patternability due to their planar nature that is essential for high-volume manufacturing said Banerjee.

graphene has no band gap. Stepping stones to a Unique Statea material band gap is fundamental to determining its electrical conductivity.
Imagine two river crossings, one with tightly-packed stepping-stones, and the other with large gaps between stones.
A band gap is much the same; the smaller the gap the more efficiently the current can move across the material and the stronger the current.
Graphene has a band gap of zero in its natural state, however, and so acts like a conductor;
The one big difference between the two is BP natural band gap allowing the material to switch its electrical current on and off.
