The Quantum Interference Effect Transistor
D. M. Cardamone, C. A. Stafford, S. Mazumdar
We propose a new type of molecular transistor, the Quantum Interference Effect Transistor (QuIET), based on tunable current suppression due to quantum interference. We show that an…
Role of Electron--Electron Interactions on Spin Effects in Electron--Hole Recombination in Organic Light Emitting Diodes
Mousumi Das, S. Mazumdar, S. Ramasesha
We extend our theory of electron--hole recombination in organic light emitting diodes to investigate the possibility that high energy singlet and triplet excited states with large…
Electron-electron interaction effects on optical excitations in semiconducting single-walled carbon nanotubes
Hongbo Zhao, Sumit Mazumdar
We report correlated-electron calculations of optically excited states in ten semiconducting single-walled carbon nanotubes with a wide range of diameters. Optical excitation occur…
Comment on "Triplet-to-Singlet Exciton Formation in poly(p-phenylene-vinylene) Light-Emitting Diodes"
S. Mazumdar, Mousumi Das, S. Ramasesha
The low-lying singlet and triplet spectrum in conjugated polymers clearly show that the mechanism proposed by Lin et al. to explain their electric field dependence of singlet to tr…
Rung-singlet charge-ordering in alpha'-NaV2O5
R. T. Clay, S. Mazumdar
We show that the proposed zig--zag charge--ordering model for alpha'--NaV2O5 is incompatible with a single transition that induces both charge--ordering and spin gap. We introduce…
Designing pi-conjugated polymers with light emission in the infrared
S. Mazumdar, S. Dallakyan, M. Chandross
There is currently a great need for solid state lasers that emit in the infrared. Whether or not conjugated polymers that emit in the IR can be synthesized is an interesting theore…
