Confinement Highlights the Different Electrical Transport Mechanisms Prevailing in Conducting Polymers
Sukanya Das, Anil Kumar, K. S. Narayan
We study the differences in electrical charge transport dynamics of the conductivity enhancement of poly(3,4-ethylenedioxythiophene) (PEDOT) derivatives under geometrical confineme…
Studies of long-lived photogenerated carriers in low band gap polymer photodiodes
M. Bag, K. S. Narayan
Defects in low-bandgap polymer based photodetectors play a critical role in determining switching characteristics in the near infra-red spectral-regime relevant to communication wa…
Large photoresponse of Cu:TCNQ nanowire arrays formed as aligned nanobridges
Rabaya Basori, K. Das, Prashant Kumar +2
We report for the first time a large photoresponse in an array of charge transfer complex Cu:TCNQ nanowires (average diameter 30 nm) fabricated as a nanobridge device. The device s…
Polarization fluctuation dominated electrical transport processes of polymer based ferroelectric-field-effect transistors
Satyaprasad P. Senanayak, S. Guha, K. S. Narayan
Ferroelectric field-effect transistors (FE-FETs) consisting of tunable dielectric layers are utilized to investigate interfacial transport processes. Large changes in the dielectri…
Universality in Intensity Modulated Photocurrent in Bulk-Heterojunction Polymer Solar Cells
Monojit Bag, K. S. Narayan
We observe a universal feature in the frequency dependence of intensity modulated photocurrent Iph based on studies of a variety of efficient bulk-heterojunction polymer solar cell…
Nonexponetial relaxation of photoinduced conductance in organic field effect transistor
Soumya Dutta, K. S. Narayan
We report detailed studies of the slow relaxation of the photoinduced excess charge carriers in organic metal-insulator-semiconductor field effect transistors consisting of poly(3-…
Polarization-dependent discharge in fibers of semiconducting ladder-type polymer
N. Kumar, K. S. Narayan
We report results on polarization-dependent photoinduced discharge in oriented fibers and films of ladder-type, electron-transporting polymer poly (benzimidazobenzophenanthroline),…
