Organic Field-Effect Transistors Based on Small-Molecule Organic Semiconductors Evaporated under Low Vacuum

Basic small-molecule organic electron acceptors and donors such as dicyanoquinonediimine (DCNQI), tetracyanoquinodimethane (TCNQ), and tetramethyltetrathiafulvalene (TMTTF) do not smoothly form thin films by vacuum evaporation owing to the high vapor pressures. The thin films are, however, fabricate...

Description
Summary:Basic small-molecule organic electron acceptors and donors such as dicyanoquinonediimine (DCNQI), tetracyanoquinodimethane (TCNQ), and tetramethyltetrathiafulvalene (TMTTF) do not smoothly form thin films by vacuum evaporation owing to the high vapor pressures. The thin films are, however, fabricated by low-vacuum evaporation, and the resulting organic thin-film transistors have exhibited remarkably improved performance.
