Abstract
A remarkable anisotropic thermochemical hole burning (THB) phenomenon was observed on TTF−TCNQ charge-transfer complex when using a STM tip to write information bits on its single-crystal surface. Such an anisotropy of hole formation was found to be closely related to the anisotropic thermal conducting property of TTF−TCNQ crystal, strongly supporting a nanometer scale thermochemical reaction mechanism. The high thermal conductivity of TTF−TCNQ leads to a very weak dependence of hole size on the pulse duration within a certain time scale, which was never observed with ammonium−TCNQ complexes. Comparative studies using isotropic thermal conducting TEA(TCNQ)2 complex and theoretical analyses were performed for elucidating the unique hole burning properties of TTF−TCNQ complex. The thermal gravimetry combined with mass spectrometry (TG−MS) of TTF−TCNQ was also done for a detailed understanding of the thermochemical decomposition reaction.
