Abstract: The thermochemical hole burning properties of two different charge transfer complexes,DEA(TCNQ)2 and TEA(TCNQ)2,were studied in this work.It shows that the data writing on DEA(TCNQ)2 needs a larger threshold voltage compared with TEA(TCNQ)2,and that the DEA(TCNQ)2 gives a smaller hole size and a higher depth/diameter ratio,demonstrating the possibility of optimizing the storage performance with a suitable molecular design.

Key words: STM, Data storage, Thermochemical Hole Burning, Storage material
