Ultra-low doping and local charge variation in graphene measured by Raman: experiment and simulation
Zhuofa Chen, Nathan Ullberg, Mounika Vutukuru +2
Avoiding charge density variations and impurities in graphene is vital for high-quality graphene-based devices. Here, we demonstrate an optical method using Raman 2D peak-split to…
Monitoring the low doping regime in graphene using Raman 2D peak-splits: Comparison of gated Raman and transport measurements
Zhuofa Chen, Nathan Ullberg, Mounika Vutukuru +2
Avoiding charge density fluctuations and impurities in graphene is vital for high-quality graphene-based devices. Traditional characterization methods require device fabrication an…
Modeling and Thermal Metrology of Thermally Isolated MEMS Electrothermal Actuators for Strain Engineering of 2D Materials
Mounika Vutukuru, Jason W. Christopher, Corey Pollock +2
We present electrothermal microelectromechanical (MEMS) actuators as a practical platform for straining 2D materials. The advantages of the electrothermal actuator is its high outp…
