how to correct hysteresis in graphene based fets

Hysteresis is a phenomenon that occurs when two variables, such as current and temperature, vary together in a closed loop system. In the case of graphene-based fets, hysteresis can be significant, particularly when attempting to control or measure the output of a device.

In graphene-based devices, hysteresis can arise due to a number of factors, including the presence of impurities or defects in the graphene layer, the composition of the substrate material, and the geometry of the device circuit.
To correct hysteresis in graphene-based fets, it is important to understand the underlying physics behind the phenomenon. Hysteresis occurs because the change in one variable (in this case, current) causes the corresponding change in another variable (temperature), leading to an increase in energy resistance between the two variables. This increase in energy resistance means that a larger amount of electrical power must be applied before the output of the device changes significantly.
To correct hysteresis in graphene-based fets, there are several strategies that can be employed. One approach is to optimize the physical properties of the graphene layer and substrate materials, such as the thickness, aspect ratio, and composition. By adjusting these parameters, it may be possible to reduce the amount of hysteresis that occurs in the device.
Another strategy is to use techniques such as carrier injection or de to increase the density of charge carriers within the graphene sheet. These techniques can help to reduce the amount of energy required for the voltage applied to the device, thereby reducing hysteresis.
Additionally, using the appropriate voltage limits for the device can also help to reduce hysteresis. When the voltage limit is exceeded, the device will not operate at its full potential, which can lead to reduced performance and increased hysteresis.
Finally, optimizing the device geometry can also help to reduce hysteresis. By carefully designing the layout of the device circuit, it may be possible to minimize the area where the current must flow in order to achieve stable operation, which can reduce hysteresis.
