Quantum transport at the Dirac point: Mapping out the minimum conductivity from pristine to disordered graphene
Redwan N. Sajjad, Frank Tseng, K. M. Masum Habib +1
The phase space for graphene's minimum conductivity is mapped out using Landauer theory modified for scattering using Fermi's Golden Rule, as well as the Non-Equil…
Triangular lattice exciton model
Daniel Gunlycke, Frank Tseng
We present a minimalistic equilateral triangular lattice model, from which we derive electron and exciton band structures for semiconducting transition-metal dichalcogenides. With…
Graphene Nanoribbons: from chemistry to circuits
Frank Tseng, Dincer Unluer, Mircea R. Stan +1
The Y-chart is a powerful tool for understanding the relationship between various views (behavioral, structural, physical) of a system, at different levels of abstraction, from hig…
From low-bias mobility to high-bias current saturation: fundamental trade-offs in graphene based transistors
Frank Tseng, Avik W. Ghosh
We describe the fundamental trade-offs in engineering the mobility, current saturation and ON- OFF ratios in graphene transistors. Surprisingly, the trade-offs arise solely from an…
Diluted chirality dependence in edge rough graphene nanoribbon field-effect transistors
Frank Tseng, DIncer Unlcer, Katherine Holcomb +2
We investigate the role of various structural nonidealities on the performance of armchair-edge graphene nanoribbon field effect transistors (GNRFETs). Our results show that edge r…
Monolithically Patterned Wide-Narrow-Wide All-Graphene Devices
Dincer Unluer, Frank Tseng, Avik W. Ghosh +1
We investigate theoretically the performance advantages of all-graphene nanoribbon field-effect transistors (GNRFETs) whose channel and source/drain (contact) regions are patterned…
