Efros-Shklovskii variable range hopping in reduced graphene oxide sheets of varying carbon sp2 fraction
Daeha Joung, Saiful I. Khondaker
We investigate the low temperature electron transport properties of chemically reduced graphene oxide (RGO) sheets with different carbon sp2 fractions of 55 to 80 %. We show that i…

Daeha Joung, Virendra Singh, Sanghoon Park +3
This paper has been withdrawn.
Coulomb Blockade and Hopping Conduction in Graphene Quantum Dots Array
Daeha Joung, Lei Zhai, Saiful I. Khondaker
We show that the low temperature electron transport properties of chemically functionalized graphene can be explained as sequential tunneling of charges through a two dimensional a…
Space charge limited conduction with exponential trap distribution in reduced graphene oxide sheets
Daeha Joung, A. Chunder, Lei Zhai +1
We elucidate on the low mobility and charge traps of the chemically reduced graphene oxide (RGO) sheets by measuring and analyzing temperature dependent current-voltage characteris…
High yield fabrication of chemically reduced graphene oxide field effect transistors by dielectrophoresis
Daeha Joung, A. Chunder, Lei Zhai +1
We demonstrate high yield fabrication of field effect transistors (FET) using chemically reduced graphene oxide (RGO) sheets suspended in water assembled via dielectrophoresis. The…
Electronic transport properties of ternary Cd1-xZnxS nanowire network
Daeha Joung, M. Arif, S. Biswas +3
We present electronic transport characteristics of ternary alloy Cd1-xZnxS nanowire networks in the dark and under white light illumination. Compared to the negligible dark current…
