title: Field emission from nanorod crystalline films of a strong organic electron donor, tetrathiotetracene.
abstract: A strong electron donor, tetrathiotetracene (TTT), with low ionization potential (6.27 eV), low electron affinity (1.10 eV), high conductivity (up to 10(-5) S/m) and good thermal stability (melting point approximately 375 degrees C) was introduced into field emitters. Nanorod crystalline films of TTT were synthesized by vacuum deposition depending on the strong pi--pi interaction between TTT molecules. The nanorod films exhibited excellent field emission properties with a turn-on field of 11.1-11.3 V/microm, a maximum current density of 5.0-7.1 mA/cm2 at an applied field of 25 V//microm, which indicated great potential for field emission application of the strong organic electron donor, TTT.
