Anomalous Random Telegraphy Signal in Suspended Graphene with Oxygen Adsorption [PDF]

open access: yes, 2023
Graphene is a promising material for sensing applications because of its large specific surface area and low noise. In many applications, graphene will inevitably be in contact with oxygen since it is the second most abundant gas in the atmosphere. Therefore, it is of interest to understand how this gas affects the sensor properties.
