Hysteresis and charge trapping in graphene quantum dots

(author unknown)



Hemen Kalita, Harikrishnan V, and Dhanraj B. Shinde et al.

We report current hysteresis in response to applied voltage in graphene quantum dots of average diameter 4.5 ± 0.55 nm, synthesized electrochemically using multiwalled carbon nanotubes. In response to step voltages, transient current decay, characteristic of deep and shallow level charge traps wit ... [Appl. Phys. Lett. 102, 143104 (2013)] published Mon Apr 08, 2013.
