Universal scaling of resistivity in bilayer graphene
Kalon Gopinadhan, Young Jun Shin, Hyunsoo Yang
We report the temperature dependent electrical transport properties of gated bilayer graphene devices. We see a clear evidence of insulating behavior due to electron-hole charge pu…
Shifting of surface plasmon resonance due to electromagnetic coupling between graphene and Au nanoparticles
Jing Niu, Young Jun Shin, Jaesung Son +3
Shifting of the surface plasmon resonance wavelength induced by the variation of the thickness of insulating spacer between single layer graphene and Au nanoparticles is studied. T…
Disorder-free sputtering method on graphene
Xue Peng Qiu, Young Jun Shin, Jing Niu +5
Deposition of various materials onto graphene without causing any disorder is highly desirable for graphene applications. Especially, sputtering is a versatile technique to deposit…
Graphene induced tunability of the surface plasmon resonance
Jing Niu, Young Jun Shin, Youngbin Lee +2
Tunability of the surface plasmon resonance wavelength is demonstrated by varying the thickness of Al2O3 spacer layer inserted between the graphene and nanoparticles. By varying th…
The role of charge traps in inducing hysteresis: capacitance - voltage measurements on top gated bilayer graphene
Gopinadhan Kalon, Young Jun Shin, Viet Giang Truong +2
Understanding the origin of hysteresis in the channel resistance from top gated graphene transistors is important for transistor applications. Capacitance - voltage measurements ac…
Frictional characteristics of exfoliated and epitaxial graphene
Young Jun Shin, Ryan Stromberg, Rick Nay +4
To determine the friction coefficient of graphene, micro-scale scratch tests are conducted on exfoliated and epitaxial graphene at ambient conditions. The experimental results show…
Tunable metal-insulator transitions in bilayer graphene by thermal annealing
Gopinadhan Kalon, Young Jun Shin, Hyunsoo Yang
Tunable and highly reproducible metal-insulator transitions have been observed in bilayer graphene upon thermal annealing at 400 K under high vacuum conditions. Before annealing, t…
