Intrinsic metallic nature
in conducting polymers
Although doped polyacetylene [PA, conductivity ~ 1000 S/cm], polyaniline (PANI) and polypyrrole
(PPy) [conductivity ~ 100 S/cm] have been
investigated during the 1980’s, hardly any positive temperature coefficient of
resistivity (TCR) was observed. Our early 90’s work on a new type of PANI has
helped to resolve the role of disorder in charge transport, and the subsequent
work on PPy could reveal the positive TCR in these
systems. Furthermore, the facile tuning of the critical regime to metallic and
insulating regimes by pressure and magnetic field has been shown in several conducting
polymers. The novel electrochemically gated transistor studies could show the
evolution of the density of states and conductivity in conducting polymers.
Recently (Nature Mat. 8, 572,
2009) the Luttinger liquid scenario has been demonstrated in a
semiconducting polymer.
Percolation
in fractal networks
The classical percolation
problem has been studied for several years, and the observed percolation
threshold is ~ 16 % volume fraction; however, this value is expected to be
lowered as the aspect ratio of the conducting particle increases. Nevertheless
rarely the percolation threshold is observed below 1 %. In our work on
interpenetrating fractal networks of PANI in insulating polymer matrix,
percolation thresholds as low as 0.1 % was observed, with a large conductivity
(~ 1 mS/cm). This has opened up new frontiers on
conducting polymer nanocomposites.
Anisotropic charge transport in highly
oriented conducting polymers
The intra versus inter
chain charge transport properties, in aligned conducting polymers like polyacetylene and poly-p-phenylenevinylene
(PPV), are quite significant to probe the anisotropic features. These studies
have shown that the transverse versus longitudinal magnetotransport
can determine the nanoscopic scale charge transport
parameters. How the quantum effects, due to the interplay of weak localization
and electron-electron interactions, contribute to the anisotropic magnetoconductance have been revealed from these studies.
Furthermore, determining the temperature dependence of inelastic scattering
length is of considerable importance to identify the charge carrier scattering
mechanisms.
Poly(3,4- ethylenedioxythiophene)-polystyrenesulfonic acid (PEDOT-PSS)
In the initial years of
polymer light emitting diodes (LED), the indium-tin oxide (ITO) –semiconducting
polymer interface was causing severe stability problems. Our pioneering work on
covering the ITO surface by spin coating the aqueous based PEDOT-PSS, and then
the semiconducting polymer on top of the PEDOT-PSS layer has significantly
enhanced the life-time of polymer LEDs and other polymer devices. This work has
received over 250 citations. Since PEDOT-PSS being a complex system, the nanomorphology determines the electrical properties.
Recently this aspect has been thoroughly investigated, and shown that grain
size play a major role in the charge transport properties. This work is
published as an IOP-Select paper.
Metallic state in
disordered quasi-one-dimensional conductors
The metallic state in
conducting polymers and single-walled carbon nanotubes
is studied by dielectric spectroscopy (8-600 GHz). An intriguing correlation
between scattering time (t ) and plasma frequency (wp): t µ wp-1.3 has been observed. Based
on the observed parallels with doped semiconductors, the interchain
coupling t^, plays a role comparable to the doping level, and that the unusual
free-carrier dynamics in the metallic state can be explained by including the
role of t^ in the conventional models. In polymers and nanotubes,
the competition between interchain charge transfer
and localization onto 1D chains plays a role comparable to that of doping
level. The empirical correlation between t and wp for both conducting
polymers and doped semiconductors is an important result of this work. Also,
the phase-sensitive sub-THz data have assisted to resolve the discrepancies in Kramers-Kronig analysis in earlier studies.
THz-time
domain sepectroscopy
Especially, in the case of
conducting polymers, charge carrier dynamics is dominated by the contributions
at low energies, which can be probed only by THz complex dielectric
spectroscopy. Analysis of the complex conductance data in the THz frequency
range directly gives the carrier mobility, density and relaxation time. For
metallic conducting polymers the Drude model is quite
appropriate, and for insulating systems the localization-modified Drude model is used. The low-energy carrier dynamics is
determined by the combination of coherent and incoherent transport channels
between conjugated chain segments. However, the interplay between electronic
correlations and interchain charge transfer is found
to play a major role.
Charge transport in carbon nanotubes
Charge transport in a novel form of transparent single-wall carbon nanotubes (SWNT) shows that the localization-delocalization transition is quite sensitive to the intertube transport. Hopping transport dominates in transparent SWNT network. The transparency of this network can be tuned in a gated device by controlling the doping level. Since transparent SWNT has strong potential for applications in flexible organic / polymer electronic devices, a comparative investigation on the charge transport properties with respect to other transparent electrodes like PEDOT-PSS and conventional ITO indicates that the nanomorphology of SWNT network should improve for optimizing the charge transport properties. In bulk SWNTs, both weak localization and electron-electron interactions are found to play significant role in the low temperature transport. The temperature dependence of inelastic scattering length indicates non-Fermi liquid behavior, especially in case of aligned SWNTs.
