Ambipolar charge transport in quasi-free-standing monolayer graphene on SiC obtained by gold intercalation
Kyung Ho Kim, Hans He, Claudia Struzzi +6
We present a study of quasi-free-standing monolayer graphene obtained by intercalation of Au atoms at the interface between the carbon buffer layer (Bu-L) and the silicon-terminate…
Uniform doping of graphene close to the charge neutrality point by polymer-assisted spontaneous assembly of molecular dopants
Hans He, Kyung Ho Kim, Andrey Danilov +12
Tuning the charge carrier density of two-dimensional (2D) materials by incorporating dopants into the crystal lattice is a challenging task. An attractive alternative is the surfac…
Random telegraph noise in metallic single-walled carbon nanotubes
Hyun-Jong Chung, Tae Woo Uhm, Sung Won Kim +5
We have investigated random telegraph noise (RTN) observed in individual metallic carbon nanotubes (CNTs). Mean lifetimes in high- and low-current states, shigh and slow, have been…
Photocurrent Imaging of p-n Junctions and Local Defects in Ambipolar Carbon Nanotube Transistors
Y. H. Ahn, Wei Tsen, Bio Kim +2
We use scanning photocurrent microscopy (SPCM) to investigate the properties of internal p-n junctions as well as local defects in ambipolar carbon nanotube (CNT) transistors. Our…
