Spin Valve Effect in ZigZag Graphene Nanoribbons by Defect Engineering
Sankaran Lakshmi, Stephan Roche, Gianaurelio Cuniberti
We report on the possibility for a spin valve effect driven by edge defect engineering of zigzag graphene nanoribbons. Based on a mean-field spin unrestricted Hubbard model, electr…
Negative differential resistance in nanoscale transport in the Coulomb blockade
Prakash Parida, S Lakshmi, Swapan K Pati
Motivated by recent experiments, we have studied transport behavior of coupled quantum dot systems in the Coulomb blockade regime using the master (rate) equation approach. We expl…
Long range electron transfer across -conjugated systems: role of electron correlations
S. Lakshmi, Ayan Datta, Swapan K. Pati
We consider a prototype polyene chain: donor-(bridge)-acceptor. The distance between the donor and the acceptor is varied by increasing the number of bridged atoms and rate of e…
