“…The I-V curves measured by the C-AFM on the surface of semiconducting materials can be associated with different charge transport processes across the probe-sample interface [40][41][42][45][46][47][48][49][50][51]. V is SCLC in agreement with previously reported data for LMO [25].…”

Percolation-dominated conductivity in a conjugated-polymer-carbon-nanotube composite

We have made electrical measurements on a system using carbon nanotubes as the dopant material. A semiconjugated, organic polymer was mixed with carbon nanotubes to form a wholly organic composite. Composite formation from low to high nanotube concentration increases the conductivity dramatically by ten orders of magnitude, indicative of percolative behavior. Effective mobilities were calculated from the spacecharge regions of the current-voltage characteristics for the 0-8 % mass fractions. After an initial rise these were seen to fall from 1-8 % doping levels as predicted by theory. From the values for conductivity and mobility, an effective carrier density was calculated. This was seen to decrease between 0% and 1%, before rising steadily. ͓S0163-1829͑98͒51536-6͔

“…Generally speaking, structural disjunctions in dislocation cores can disrupt extended wave functions [381], where miso riented molecules serve as trap for excitations [382,383]. Dislocations can hinder electron transport in aromatic solids such as naphthalene, anthracene [384][385][386][387], tetracene (C 18 H 12 ) [388], perylene (C 20 H 12 ) [389], p-terphenyl, p-quaterphenyl (C 6 H 5 C 6 H 4 C 6 H 4 C 6 H 5 ) [390], and phthalocyanine (C 32 H 18 N 8 ) [254,[391][392][393]. Higher trap densities in anthracene correlated with higher dislocation densities when grown from the melt relative to vapor [381].…”

Dislocations in molecular crystals

Dislocations in molecular crystals remain terra incognita. Owing to the complexity of molecular structure, dislocations in molecular crystals can be difficult to understand using only the foundational concepts devised over decades for hard materials. Herein, we review the generation, structure, and physicochemical consequences of dislocations in molecular crystals. Unlike metals, ceramics, and semiconductors, molecular crystals are often characterized by flexible building units of low symmetry, thereby limiting analysis, complicating modeling, and prompting new approaches to elucidate their role in crystallography from growth to mechanics. Such considerations affect applications ranging from plastic electronics and mechanical actuators to the tableting of pharmaceuticals.
