“…NIPG) which in turn make threedimensional continuous conduction paths. 21 T induced I-V characteristics (Fig. 6a) are noted and revealed for 50, 75, 100, and 150 K. Despite this, above 150 K NIPG shows a symmetrical Ohmic nature, with depletion of T, reversible nonlinearity is amplied anomalously, where around zero bias a zero current plateau appears signifying saturation of NIPG resistance owing to self-heating effect.…”

A straightforward novel synthetic approach of manganese ferrite encapsulated poly [3,4-(ethylenedioxy) thiophene] nanocomposite decorated on a graphene layer (NIPG) is engineered assisted by dodecyl benzene sulphonic acid as surfactant. NIPG is characterized by Raman, TG, SEM, EDX, AFM, TEM etc. The temperature-induced (50 to 300 K) I-V characteristics and conductivity are scrutinized for NIPG and the structure-property relationship for electrical transport is also demonstrated. Varying loading of manganese ferrite nanoparticle and graphene significantly improve the order of conductivity even in a low temperature regime due to development of charge carriers such as polaron, bipolaron etc. in the band structure. An anomalous 3D Mott variable range hopping mechanism provides a complete framework to comprehend transport in NIPG. 12 841 3553; Tel: +27 12 841 7845 † Electronic supplementary information (ESI) available.

The optoelectronic and charge transport properties of eight linearly fused Napthadithiophene (NDT) molecules with different electron‐withdrawing (EWG) and electron‐donating (EDG) substituents are studied using the density functional theory (DFT) methods. The effect of the substitution of EWG and EDG on the molecular structure, frontier molecular orbitals, ionization energy, electron affinity, reorganization energy, crystal packing, and charge carrier mobility are studied. The crystal structure simulation method is used to optimize the possible crystal packing arrangements for the studied molecules. The energy and distribution of electron density on the frontier molecular orbitals are strongly influenced by the substitution of EWG and EDG, thereby changes in the absorption spectrum and charge transport properties. The unsubstituted NDT molecule possesses a maximum hole mobility of 2.8 cm2 V−1 s−1, which is due to the strong intermolecular interactions. Therefore, the NDT molecule can be used as a p‐type semiconducting material. Among the studied molecules, the CCH‐substituted NDT molecule, NDT‐CCH, possesses a higher electron mobility of 1.13 cm2 V−1 s−1. The C2H5‐substituted NDT molecule, NDT‐C2H5, possesses ambipolar behavior with mobility of 4.77 × 10−2 cm2 V−1 s−1 and 1.70 × 10−2 cm2 V−1 s−1 for hole and electron, respectively.
