What is gtl?

GTL, or Graphene Transfer Length, is a critical parameter in characterizing the performance of graphene-based electronic devices. It represents the length over which the current density decays exponentially from the contact edge into the graphene channel. A shorter GTL generally indicates better electrical contact between the metal electrode and the graphene, leading to improved device performance. Several factors influence the GTL, including the contact resistance, graphene's intrinsic conductivity, and the gate voltage. Understanding and minimizing GTL is crucial for optimizing graphene-based transistors, sensors, and other electronic components.

Key aspects to consider:

• Definition: The distance over which current decays exponentially from the metal-graphene contact.
• Importance: Indicates the quality of the electrical contact; shorter GTL is preferred.
• Influencing Factors: This includes Contact%20Resistance, Graphene%20Conductivity, and applied gate voltage.
• Applications: Optimizing graphene-based Transistors and Sensors.
